FROM a small blank-book of Lewis's,[1] which he had
also used when an army paymaster in 1800. These
notes were apparently written during the winter of
1803–04, at River Dubois. The book also contains meteorological
data, which will be given post.—Ed.]

The Kickapoo calls a certain water plant with a large Circular floating
leaf found in the ponds and marshes in the neighbourhood of Kaskaskias
and Cahokia, Po-kish'-a-co-mah', of the root of this plant the
Indians prepare an agreeable dish, the root when taken in it's green
state is from 8 to 14 inches in circumpherence is dryed by being
exposed to the sun and air or at other times with a slow fire or smoke
of the chimnies, it shrinks much in drying. The root of this plant
grows in a horrizontal direction near the surface of the rich loam or
mud which forms the bottoms of their ponds or morasses, generall[y]
three, sometimes four or more of these roots are attatced together by a
small root or string of a hearder substance of a foot or six inches in
length, the root of the plant thus annually progresses shooting out a
root from a bud at the extremity of the root of the presceeding years
groath, this in the course of the summer p[r]oduces a new root prepared
with a bud for the progression of the next season, also one leaf
and one seed stalk the stem of the former supporting or reather attatched
to a large green circular leaf 18 inches to two feet in diameter which
fl[o]ats while green usually on the serface of the water, the sta[l]k is
propotioned to the debth of the water, and of a celindrical form, is an
inch and a half in circumpherence at or near it's junction of the root
thence regularly tapering to the leaf where it is perhaps not more than
an inch, the large fibers of the leaf project from the extremity of the
stalk in every direction at right angles from it to the circumpherence of
the leaf like rays from the center, there are from twelve to eighteen of
those fibers. the leaf is nearly a circle smoth on both sides and even
and regular on it's edges near the same part of the root from which the
leaf stalk project the seed stalk dose also it is about the same size and
form of it but usually a foot longer standing erect and bearing it[s]

blossum above the surface of the water which I am informed is of a
white colour.

The seed vessel or matrix is the form of a depressed cone the small
extremity of which is attatc[h]ed to the uper end of the stalk; before it
has attained it's groath it resembles an inverted cone but when grown
the base obtains a preponderancy and inclining downwards rests it's
edge against the stalk the base is a perfect circular plain from eighteen
to twenty inches in circumpherence in it's succulent state, and from two
to three inches in hight. the surface of the cone when dryed by the
sun and air after being exposed to the frost is purforated with two circular
ranges of globular holes from twenty to 30 in number arond one
which forms the center placed at the distance of from an eighth to
1/4 of an inch assunder, each of those cells contains an oval nut of a light
brown colour much resembling a small white oak acorn smothe extreemly
heard, and containing a white cernal of an agreeable flavor;
these the native[s] frequently eat either in this state or roasted; they frequently
eat them also in their succulent state the bear feed on the leaves
of this plant in the spring and summer in the autumn and winter the
Swan, geese, brant, ducks and other acquatic fowls feed on the root,
the cone is brown, pithy and extreemly light, and when seperated from the
stalk flots on the suface of the water with its base down. the Indians
procure it and prepare it for food in the following manner—they enter
the ponds where it grows, barefooted in autumn, and feel for it among
the mud which being soft and the root large and near the surface they
readily find it they easily draw it up it having no fiborus or colateral
roots to attatch it firmly to the mud they wash and scrape a thin bleack
rind off it and cut it croswise into pieces of an inch in length when it
is prepared for the pot it is of a fine white colour boils to a pulp and
makes an agreeable soupe in which way it is usually dressed by the natives
when they wish to preserve it for any length of time they cut it
in pieces in the manner before discribed string it on bark or leather
throngs of a convenient length and hang it to dry in the sun, or expose
it to the smoke of their chimnies, when thus dryed it will keep for several
years, it is esteemed as nutricius as the pumpkin or squash and is
not very dissimilar in taste The Chipiways or sateaus call this plant
Wab-bis-sa-pin or Swan-root The ferench or Canadians know it by two
names the Pois de Shicoriat or Graine de Volais. the roots of this
plant are from one foot to eighteen inches in length.

The common wild pittatoe also form another article of food in savage
life this they boil untill the skin leaves the pulp easily which it will do
in the course of a few minutes the outer rind which is of a dark brown


139

Page 139
coulour is then sc[r]aped off the pulp is of a white coulour, the pettatoe
thus prepared is exposed on a scaffold to the sun or a slow fire untill it
is thoroughly dryed, or at other times strung upon throngs of leather or
bark and hung in the roofs of their lodges where by the influence of the
fire and smoke it becomes th[o]roughly dryed, they are then prepared
for use, and will keep perfectly sound many years, these they boil with
meat or pound and make an agreeable bread of this pittaitoee may
be used in it's green or undryed state without danger provided it be well
roasted or boiled it produces a vine which runs to a considerable length
usually intwining itself about the neighbouring bushes and weeds, the
vine is somewhat branched, and in it[s] progress at the distance of 2 1/2
inches it puts forth one leaf stem at right angles with the vine, which is furnished with two par of ovate leaves and turminated by one of a
similar shape, these are of a pale green colour not indented on their
edges, reather a rough appearance, the vine is small and green except
near the ground where it sometime[s] assumes a redish hue. the fruit
is connected by a small liggament at both ends extending for many yards
in length and attatching together in some instances six eight or more of
these pittaitoes. it's root is pereniel the vine annual.

There is also another root found in ma[r] shey land or ponds which
is much used by the Kickapoos Chipaways and many other nations as
an article of food it is called by the Chipeways Moc-cup-pin this in
it's unprepared state is not only disagreeable to the taste but even dangerous
to be taken even in a small quantity; in this state it acts as a
powerfull aemetic. a small quantity will kill a hog yet prepared by the
Indians it makes not only an agreeable but a nutricious food. I have
not seen the plant and can therefore only discribe it from Information
the leaf is said to be broad and to float on the water the root is from
10 to 12 inches in length and about 2/3ds. as much in thickness it has
a rough black skin, the pulp is white and of a mealy substance when
properly prepared the preparation is this—having collected a parsel of
these roots you cut and split a sufficient parsel of wood which is set on
end as the coliers commence the base of their coal pitts, the [l]engths of
these sticks of wood being as nearly the same as you can conveniently
cut them and about 4 feet in length thus forming when put together an
even surface at top on this is thrown soft earth of from two to 3
Inches in debth the roots are laid on this and earth thrown over the
whole forming the Colliers kiln complete. fire is then communicated
to the wood beneath and it is suffered to burn slowly for several days
untill the wood is exausted or they concieve their roots are sufficiently
cooked they then take them out scrape them & cut them into slices

crosswise of half an inch thick and laying them on a scaffold of small
sticks build small fires under them and dry them untill they become perfectly
firm thus prepared they are fit for uce and will keep for years if
not exposed to wet. they are either boiled to a pulp in their soupe or
less boiled eat them with bears oil or venison and bears flesh they
sometimes pound it and make a bread of it.[2]

A List of specimines of plants collected by me on the Mississippi and
Missouri rivers contain such observations on the vegitable kingdom
spread to our view in this rich country as they have occurred to my
mind. or as the several subjects have presented themselves to my
view.

    No. 1.

  • a species of Cress taken at St. Louis May 10th. 1804. it is
    common in the open grown[d]s on the Mississippi bottoms, appears in
    the uncultivated parts of the lots gardens and orchards, the seed come
    to maturity by the 10h. of May in most instances.

  • No. 2.

  • was taken on the 22ed. of May 1804 on the bank of the Missouri
    about 8 miles above St. Charles it is common in the botom lands—rises
    to the hight of two feet, and rarely puts forth more than two stalks from
    the same root and most commonly only one it's root is spiral.

  • No. 3.

  • Was taken on the 23rd. of May 1804, near the mouth of the
    Osage Woman's creek, it is a srub and resembles much in growth the
    bladder scenna, it rises to [the] hight of eight or ten feet and is an inhabitant
    of a moist rich coil. usually the verge of the river bank. it
    is a handsome Shrub

  • No. 4.

  • Was taken at a small Village North side of the Missouri
    called Sharetton on the 25th. of May 1804. this is the last settlement
    on the Missouri; and consists of ten or twelve families mostly hunters.
    this specimine is the seed of the Cottonwood which is so abundant in


    143

    Page 143
    this country, it has now arrived at maturity and the wind when blowing
    strong drives it through the air to a great distance being supported by a
    parrishoot of this cottonlike substance which gives the name to the tree
    in some seasons it is so abundant as to be troublesome to the traveler.
    this tree arrives at great sise, grows extreemly quick the wood is of a
    white colour, soft spungey and light, perogues are most usually made
    of these trees, the wood is not durable nor do I know any other valuable
    purpose which it can answer except that just mentioned. this tree
    forms a great majority of the timber bordering the rivers Missouri and
    Mississippi; it extends itself throughout the extensive bottom lands of
    these streams and seases to appear when the land rises into hills when
    these rivers form new lands on their borders or Islands in their
    st[r]eams, which they are per[pe]tually doing, the sweet willow is the
    first tree or shrub which usually makes it's appearance, this continues
    one two or three years and is then supplanted by the Cottonwood which
    invariably succeedes it. this tree resembles much in it's air and appearance
    that beatifull and celibrated tree the Lombardy poplar; and more
    particularly so when in its young state; the young plants grow very
    close untill they have attained the age of four or five years, a proportion
    of them then begin to dye and the forrest opens and gives place to
    sundry other shrubs and plants which will be noticed in their proper
    places.

  • No. 5.

  • was taken on the 27th. of May 1804, near the mouth of the
    Gasconade; it is a species of cress which grows very abundantly alonge
    the river beach in many places; my men make use of it and find it a
    very pleasant whol[e] some sallad.

  • No. 6.

  • Was taken on the 27th. of May 1804, near the mouth of the
    Gasconade; it is a species of rope or kail, it grows on the beach of the
    river, when young my men used it [as] a boiled green and found [it]
    healthy and pleasant.

  • No. 7.

  • was found on the 27th. of May 1804, near the water side about
    10 miles below the mouth of the Gasconade, it rises to the hight of three
    feet and puts forth many large suculent branched stalks from the same
    root, this plant is a stranger to me.

  • No. 8.

  • Was taken the 29th. of May 1804, below the mouth of the
    Osage Rivr. this plant is known in Kentuckey and many other parts
    of this western country by the name of the yellow root. it is a sovereighn
    remidy for a disorder common in this quarter called the soar
    eyes this complaint is common it is a violent inflamation of the eyes
    attended with high fevers and headach, and is extreemly distressing, and
    frequently attended with the loss of sight. this root affords a speady


    144

    Page 144
    and efficasieus remidy for this disorder prepared & used in the following
    manner.—let the roots be geathered washed and carefully dryed in
    the shade; brake them in pieces of half an inch in length and put them
    in a bottle or viol, taking care to fill the vessel about two thirds full of
    the dryed root, then fill the vessell with could water, rain water is preferable;
    let it remain about six hours shaking it occasionally and it will
    be fit for use; the water must remain with the root and be applyed to
    the eyes frequently by weting a piece of fine linin [and] touching them
    gently with it. this root is a fine aromatic bitter, and a strong asstringent;
    it is probable that it might be applyed in many cases as a medicene
    with good effect, but I have not learnt that any experiment has been
    made by an inward application. it makes an excellent mouth water,
    and a good outward applycation for wounds or inflamations of every kind.
    native of rich bottom lands on the rivers.

  • No. 9.

  • Was taken on the 30th. of May 1804, below the mouth of the
    Osage river; it rises from 18 Inches to 2 feet in hight; is a beautifull
    green plant found most generally on the sides of rich hills in the forrest
    it's radix is fiberous.

  • No. 10.

  • This plant was taken the 1st. of June at the mouth of the
    Osage river; it is known in this country by the name of the wild ginger,
    it resembles that plant somewhat in both taste and effect, it is a strong
    stomatic stimelent, and freequently used in sperits with bitter herbs. it
    is common throughout the rich lands in the Western country.

  • No. 11.

  • Was taken the 3rd. of June above the mouth of the Osage
    river; it is the groath of high dry open praries; rises to the hight of 18
    inches or two feet puts forth many stems from the same root; the
    radix is fiborous; the Indians frequently use the fruit of this plant to
    alay their thirst as they pass through these extensive dry praries common
    to many parts of the country bordering on the Missouri; it resembles
    much the Indigo in the appearance of it's growth. it bears it's fruit
    much like the indigo, a stem projects about three inches from the main
    stem at an angle of about 20 degrees, and bears from [two] to four
    podds, which in their succulent and unripe state as at this season of the
    year are about the size of a pullet's egg, somewhat flattened on two
    sides; the matrix is formed in two lobes and the seed are like pees and
    attatched to the matrix in the same manner, single and adhering to the
    center the pulp is crisp & clear and tasts very much like the hull of a
    gardin pee. when ripe the fruit is of a fine red coulour and sweet flavor.
    it dose not ripen untill the middle of June.

  • No. 12.

  • 1st. of august 1804, one of our hunters brought us a bough
    of the purple courant, which is frequently cultivated in the Atlantic


    145

    Page 145
    states; the fruit was ripe; I presume it is a native of North America
    here it grows generally in the praries but is not very abundant. No. 12
    is a specimine of it's leaves.

  • No. 13.

  • The narrow leaf willow taken on the 14th. of June. this
    tree is male and female, the female bearing it[s] seed in a small pod
    (small ova form) of three lobes, or devisions these pods are attatched
    to a stem which projects from the small boughs, and are from thirty to
    fifty in number, about this season they begin to ripen, when the pods
    burst and a great number of small seeds each furnished with a parrishoot
    of a cottonlike substance are discharged from those cels. they
    readily float in the air and are driven by the wind to a great distance,
    they are so abundant at some times as to be disagreeable to the traveller.
    the male plant has a sucession of it's flowers, commencing to
    bloom about the 1st. of June and continuing untill the 1st. of August,
    they are a small tausel of a half, or 3/4 of an inch in length, round, and
    tapering to the extremity, puting frort[h] from it's sides an infinite
    number of small stamens of a brown colour. it's leaves are numerous
    narrow, slightly indented, of a yellowish green, on the uper side, and
    whiteish green underneath, pointed, being widest in the middle which
    rarely exceeds 1/8th of an inch, it is smoth, tho' not glossey.

    This tree is invariably the first which makes it's appearance on the
    newly made Lands on the borders of the Mississippi and Missouri, and
    seems to contribute much towards facilitating the operation of raisin[g]
    this ground still higher; they grow remarkably close and in some
    instances so much so that they form a thicket almost impenetrable the
    points of land which are forming allways become eddies when overflown
    in high water these willows obstruct the force of the water and
    makes it more still which causes the mud and sand to be deposited in
    greater quantities; the willow is not attal imbarrassed or injured by this
    inundation, but puts forth an innumerable quantity of small fibrous
    roots from every part of its trunk near the surface of the water which
    further serve to collect the mud, if there happens not to be a sufficient
    quantity of mud depossited in the one season to cover the trunk of the
    willow as high as these capillery roots when the water subsides they
    fall down and rest on the trunk of the tree and conceal it for 18 or 20
    Inches; these capillery roots now perish and the willow puts forth
    other roots at the surface of the ground which enter it and furnish the
    tree with it's wanted nutriment this willow never rises to any considerable
    size, it is seldom seen larger than a mans arm, and scarcely
    ever rises higher than 25 feet. the wood is white light and tough, and
    is generally used by the watermen for setting poles in preference to any


    146

    Page 146
    thing else. as the willow incre[a]ses in size and the land gets higher
    by the annu[a]l inundations of the river, the weeker plants decline dye
    and give place to the cottonwood which is it's ordinary successor, and
    these last in their turn also thin themselves as they become larger in a
    similar manner and leave the ground open for the admission of other
    forest trees and under brush. these willow bars form a pleasant beacon
    to the navigator at that season when the banks of the river are tumbling
    in, as they [are] seldom high and rearly falling in but on the contrary
    most usually increasing.

  • No. 14.

  • The wide leaf willow or that species which I believe to be
    common to most parts of the Atlantic States. it grows in similar situations
    to that discribed with rispect to the narrow leaf willow, but is
    never found in such abundance, it arrives to greater size some times to
    forty feet in hight and eighteen inches in diameter, the leave is smoth
    ovate, pointed, finely indented, a pale green on the upper side and of
    a whiteis[h] green or silver colour underneath. like the narrow leaf
    willow the leaf is widest in the middle where it is from one inch to 3/4
    wide. it bears it's seed in the manner discribed of the other and the
    plants ar[e] likewise male and female.

  • No. 15.

  • Was taken on the 20th. of July, a bieniel plant, an inhabitant
    of the open praries or plains, high situations, where the grass is
    low. the flower is a pale purple colour small form a kind of button
    of a long cone like form which terminate[s] it's branches which are
    numerous. it grows abo[u]t 2 1/2 or three feet high. it is a stranger
    to me. the leaves are small and narrow, and divided into three on a
    stem

  • No. 16.

  • this is much the same as No. 15. with this difference that
    the blume of the conic tausel are white in stead of purple and it's leaves
    single fewer and longer.

  • No. 17.

  • Taken on the 27th. of July, the appearance of the bush is
    much like the privy and about the same hight it grows about the
    borders of the open praries it's leaf is a deep green, ovate 1 1/2 to 1 1/4
    inches long 1/2 inch wide finely indented plan[t] piennial. the buries
    or fruit a small round bury of a deep perple coulour nearly black, has
    three seed formed like the third part of a globe split by the meeting of
    two plains at it's axcis. I do not know whether birds eat them or not.
    they look handsome but tast insipid, this is a groath with which I
    am not acquainted.

  • No. 18.

  • was taken 30th. July grows in the praries in high situations,
    it's radix is pe[r]ennial, it grows about three 1/2 or 4 feet high it has
    a long top root is but little branced, it's colateral brances are short


    147

    Page 147
    and furnished with many leaf stems which are garnished by a great
    number of small leaves which are attatch[ed] by pairs on either side
    and resemble some of the sensative bryers, tho I could not discover that
    this plant partook of that quality. it's flower is of a gloubelar form
    composed of a number of fibers of a yellowish white, and produces as a
    fruit a bunch of little pees which are all bent edgeways into the form
    of a semicircle and so closely connected and compressed as to form a
    globular figure of a curious appearance.

  • No. 19.

  • Taken at the old village of the little Osages; the seed were
    now ripe; it grew in great abundance in the prarie from five to six feet
    high; it gave the plain much the appearance of an extensive timothy
    meadow ready for the sythe, the small birds feed on the seed which are
    very abundant resembling in size shape and colour those of the flax;
    when ripe they fall very easily from the stem. the leaf of this grass
    dose not decline or wither as many others do at the time the seed ripens
    but still continues succulent and green. it continues throughout the
    summer to put up a succession of young succors which in turn bear a
    large quantity of seed: this succession of crops continues throughout
    the season without the declining or withering of the stalk or leaves of
    the mother plant. the horses were very fond of this grass and I am disposed
    to believe that it would make a valuable grass for culture. this
    grass is common in the praries or bottom lands as high as the river
    Platte and perhaps further it is a fine sweet grass and I am confident
    would make good hay.

  • No. 20.

  • A specemine of wild Rye taken on the 27th. of July, this
    grass is common to all the low praries above the Cancez river. it rises
    to the hight of six feet and upwards and resembles the rye extreemly in
    appearance the geese and ducks feed on it when young, as they do
    also on the grain when ripe in September and October it produces
    much grain tho of an inferior quality compared with cultivated rye.

  • No. 21.

  • is another species of the wild rye it dose not grow as tall as
    No. 20. neither does it like that species confine itself so much to the
    open ground; it is sometimes found in the timbered land. the grain it
    produces is [n]either so large or so abundant as the former.

  • No's. 22, 23, 24 & 25,

  • Are various species of grasses which appear
    in the praries, No. 23. is the most common of any other grass, it rises
    to the hight of from 4 to 8 feet and never bears any flower or seed that
    I ever observed and suppose therefore that it must propegate by means
    of the root: common to all praries in this country.

  • No. 26.

  • Taken on the 2ed. of August in the p[r]arie at the Cuncil
    bluff. it is a species of honeysuccle and the tube of the flour is very


    148

    Page 148
    small and short they smell precisely like the English Honeysuccle so
    much admired in our gardens; this is a shrub and dose not run or vine.
    the vining honesuccle which bears a red flour is also common to the
    Illinois and is found as high up the Missoury as the mouth of the
    Kancez river above which I have not observed it. this species of shrub

stalk, tho' they increas in numbers. The indians cultivate it in the
following manner they prepare hills at the distance of about 2 1/2 feet
from each other, and leavel the top nearly leaving it somewhat convex.
in those hills they sew the seed as early in the spring as the climate will
permit them to prepare the earth say latter end of April; they keep the
hills clear of weeds and grass by plucking it from among the stalks of
tobacco with their fingers and sometimes allso thin the stalks of
tobacco by plucking up the weaker stalks tho they leave many stalks
to grow on each hill. when the tobacco begins to form it's seed poods
it is then ready for the knife when a great portion from each hill is cut
and hung on sticks untill it is nearly dry when they form them into
carrots of the thickness of a mans arm role them closely with willow
bark and hang them in the smoke of their lodges to dry. in forming
the carrot they put the butts or lower parts of the stalks together.
where the tobacco is cultivated with a view to make carrots the stalks
are so thick that they do not attain a thickness at the largest part of the
stern greater than that of a small quill. They esteem much more the
corroller dryed for the purpose of smoking and for this purpose leave
some plant [s] more widely seperated from each other in which situation
they produce a greater abundance of flowers & seed they begin to
blume in the month of [blank space in MS.] and continue untill the
first frost; during the full blume of the flower they pluck the corrollar
together with the flower and discarding the latter suffer the former to
dry in the shade when perfectly dryed it resembles at first view the
green tea and in that state it is smoked by the indians and I found it
very pleasent. it dose not affect the nerves in the same manner that
the tobacco cultivated in the U'S. dose. The smaller species of this
plant differs but little from this just discribed. it is cultivated in the
same manner and bears a flower like the other only smaller. the only
difference is the form of the leaf, which is larger say 4 times the size
and ovate they dry this on sticks and use it in that manner it is

☞it is worthy of remark that the recares never use sperituous
liquors.
Mr. Tibeau informed me that on a certain occasion he offered
one of their considerate men a dram of sperits, telling him it's virtues
the other replyed that he had been informed of it's effects and did not
like to make himself a fool unless he was paid to do so that if Mr. T.
wished to laugh at him & would give him a knife or breech-coloth or
something of that kind he would take a glass but not otherwise.

This plant is known in Kentucky & many other parts of the Western
Country by the name of the yellow root. It is said to be a sovereign
remedy in a disorder common to the Inhabitants of the Country where
found, usually termed sore eyes—frequently attended with high fever
& sometimes terminates in the loss of sight, always gives great pain &
continues for a length of time in most cases. The preparation &
application of the root is as follows—having procured a quantity of
the roots, wash them clean & suffer them to dry in the Shade, break
them with the fingers as fine as you conveniently can, put them in a glass
vessel, taking care to fill it about 2/3 with the Broken root, then add
rain or river water until the Vessel is filled, shake it frequently & it will
be fit for use in the course of 6 hours. The Water must not be decanted
but remaining with the root is to be frequently applied by wetting
a piece of fine linnen and touching thee Eyes gently with it. This
root has a fine aromatic bitter taste, it is probable that it might be
applied internally in many cases with good effect, but I have not learnt.
that any experiments have yet been made with it in that way. It
makes an excellent mouth water & is an excellent outward application
in cases of wounds or local application of any kind. It is the Growth
of rich bottom lands.

Fort Mandan March 5, 1805.

This specimen of a plant [H.] common to the praries in this quarter
was presented to me by Mr. Hugh heney a gentleman of rispectability
and information who has resided many years among the natives of this
country from whom he obtained the knowledge of its virtues. Mr.
Haney informed me that he had used the root of this plant frequently
with the most happy effect in cases of the bite of the mad wolf or dog
and also for the bite of the rattle snake he assured me that he had
made a great number of experiments on various subjects of men horses
and dogs particularly in the case of madness where the symptoms were
in some instances far advanced and had never witnessed it's failing to
produce the desired effect. the method of using it is by external application,
to half an ounce of the root finely pulverized, add as much water
as is necessary to reduce it to the consistency of a common poltice and
apply it to the bitten parts, renewing the dressing once in twelve hours.
in cases of the bite of the mad dog where the wound has healed before
the symptoms of madness appear, the bitten part must be lacerated or


158

Page 158
sca[r]efyed before the application is made. the application had always
better be made as early as possible after the injury has been sustained.

I have sent herewith a few pounds of this root, in order that experiments
may be made by some skillful person under the direction of the
P[h]ilosophical society of Philadelphia.

I have the honor to bewith much rispect,
Your Ob't Servt.

"Po-kish-a-co-mah" is unmistakably the native nelumbium, Nelumbo lutea.
The "wild pittatoe" is probably Ipomœa pandurata, though the leaf description is
very misleading. "Moc-cup-pin" is probably Nymphœea reniformis, also sometimes
called Nymphœea tuberosa or Castalia tuberosa.—William Trelease, director of
Missouri Botanical Garden, St. Louis.

[3]

Dr. Trelease furnishes us with the following memoranda on the plants and trees
named in the following list:

"Prickly pear" is an Opuntia—probably 0. Missouriensis, from its geographical position.

Several species of oak less than 480 miles from the mouth of the Missouri River would undoubtedly
be, besides the red oak noted (Quercus rubra, or more probably Q. Scbneckii),Q. velutina (sometimes
called Q. tinctoria), Q. Marylandica (sometimes called Q. nigra), Q. imbricaria, Q. alba,
Q. minor
(sometimes called Q. stettata), Q. macrocarpa and Q. platanoides (sometimes called
Q.bicolor).

"Iron wood" may refer to Carpinus Caroliniana or to Ostrya Virginica.

"Popaw" is Asimina triloba.

"Arrow wood," though this sometimes has been applied to the Osage orange, probably refers to
Viburnum dentatum or V. molle.

"Green Bryar" is probably Smilax rotundifolia.

"Pacan" is Carya olivaeformis, sometimes known as Hicoria pecan.

"Grapes of the small kind" are probably Vitis riparia.

The "White oak" is Quercus alba, but, from the locality (1370 miles from the mouth of the
river), I should think that the Burt oak, Q. macrocarpa, might be referred to here; or, more probably,
the common oak of the Rocky Mountain region, Q Garryaria, or some one of the forms
segregated from this.

"Shoemate" is Rhus, and possibly may be R. typhana, also sometimes called R. hirta.

[4]

The following identifications of plants and trees named in Lewis's list are furnished
by Dr. Trelease :

    1.

  • "Cress" is a species of Nasturtium, probably N. obtusum, sessiliflorum, or sinuatum,
    sometimes called Roripa.

  • 3.

  • Probably is the hop tree, Ptelea trifoliata.

  • 4.

  • "Cottonwood" is Populus monilifera, sometimes called P. deltoides. The trans-Missouri
    cottonwood is a variety of this sometimes called var. occidentalis and sometimes var. intermedia.

  • 5.

  • "Cress" is probably a species of Nasturtium.

  • 6.

  • "Kail," possibly Brassica Sinafistrum.

  • 8.

  • "Yellow root "may be Hydrastis Canadensis.

  • 10.

  • "Wild ginger" is a species of Asarum, perhaps A. Canadense, or more likely, A.
    reflexum
    .

  • 11.

  • Seems to be Astragalus Mexicanus.

  • 12.

  • "Purple courant" is probably Ribes floridum.

  • 13.

  • "Narrow leaf willow "is Salix longifolia.

  • 14.

  • "Wide leaf willow," from the pale under surface of the leaf, is pretty clearly Salix
    amygdaloides
    .

  • 15 and 16

  • may possibly be, respectively, Petalostemon violaceus and P. candidus, also known
    sometimes as Kuhnistera purpurea and K. candida.

  • 17.

  • From the description of the fruit would seem to be a Rhamnus, and it might possibly be
    R. alnifolia, though the leaves are very small for that.

  • 18.

  • Is Desmanthus brachylobus.

  • 26.

  • Is probably Lonicera Sullivantii.

  • 27.

  • Is probably another wild potato, Ipomœa leptophylla; though I am surprised that, if so,
    he did not learn from the Indians that its root was used by them.

  • 29.

  • Is probably Cassia Cbamaecrista.

  • 30.

  • "Wild sage" may possibly have been Salvia Pitcheri.

  • 31.

  • "Sand rush "is Equisetum arvense.

  • 32.

  • Is Gutierrezia Euthamiae.

  • 33.

  • Is Arctostaphylos Uva-ursi.

  • 40.

  • Is Grindelia squarrosa.

  • 104.

  • Is Juniperus sabina procumbens.

  • 105 and 106,

  • "Tobacco," are Nicotiana quadrivalvis.

Stewardson Brown, assistant to the curators, in charge of the herbarium of the
Botanical Section of the Academy of Natural Sciences of Philadelphia, furnishes us
with the following note upon the herbarium of Lewis and Clark :

The importance of the results of the Lewis and Clark expedition to American
botany may be appreciated when we consider what a large proportion of the plants
brought back by these pioneers were of species then unknown to science. The work
of identifying the material appears to have been entrusted to Frederick Pursh, a young
botanist, who at the time of the return of the expedition, was in Philadelphia, having
come there from Dresden several years previous for the purpose of making as thorough
a study as possible of the flora of this country; in this he achieved considerable success
—largely, it would appear, through the munificence of Dr. Benjamin Smith
Barton, then professor of botany at the University of Pennsylvania, under whose
patronage much of Pursh's work was made possible.

In 1814. Pursh published (in London) the first edition of his Flora America Septentrionalis,
two octavo volumes, of 725 pages of text and 24 plates, which contained
descriptions of the plants under consideration. Speaking of these in the preface of his
work, after a brief reference to his having made the acquaintance of Meriwether
Lewis, Pursh says : "A small but highly interesting collection of dried plants was
put into my hands by this gentleman in order to describe and figure those thought
new, for the purpose of inserting them in the account of his Travels which he was
then engaged in preparing for the press. . . . The collection of plants just spoken
of was made during the rapid return of the expedition from the Pacific Ocean to the
United States. A much more extensive one, made on the slow ascent toward the
Rocky Mountains and the chain of the Northern Andes, had unfortunately been lost,
by being deposited among other things, at the foot of those mountains. The loss of
this collection is the more to be regretted when I consider that the small collection
communicated to me, consisting of about one hundred and fifty-five specimens, contained
not above a dozen plants known to me to be natives of North America—the
rest being either entirely new or little known, and among them at least six distinct and
new genera. This may give an idea of the discerning eye of their collector, who had
but little practical knowledge of the Flora of North America. . . . The descriptions
of these plants so far as the specimens were perfect I have inserted in the present work,
in their respective places distinguishing them by the words 'v. s. in Herb. Lewis.'"
Here he refers in his descriptions to one hundred and twenty-three (123) species which
he ascribes as above, the majority of which he considered to be new to science.

For many years the bulk of these plants were entirely lost to the botanical world,
it being assumed that Pursh had taken them with him for further study when he went
to England in 1811, and had subsequently left them with his friend and benefactor,
Mr. A. B. Lambert, vice-president of the Linnean Society, under whose roof the task
of completing the work on his Flora was accomplished.

Whatever the facts in the case may be, it is certain that a number of plants marked
as coming from Lambert's herbarium and representing the type specimens of many of
the species described by Pursh in his Flora (among which are seven of the plants
received by him from Lewis) now form a part of the herbarium of the Academy of
Natural Sciences of Philadelphia; but in what manner they came into the possession
of that institution, the early records fail to show. It is not improbable, however,
that they were purchased abroad, and presented to the Academy by some early
benefactor.

These few specimens were supposed to constitute all that existed of the one hundred
and fifty-five specimens referred to by Pursh, until, in making room for improvements
at the American Philosophical Society about six years ago, were revealed among
other botanical collections in their possession several bundles of plants, the labels of
which bore a handwriting which proved to be that of Pursh; and this, together with
the data there contained, identified the plants without doubt as the missing specimens
of Lewis and Clark.

During the more than three-quarters of a century while they had been hidden from
the light of day, the beetles had not been altogether idle; and in a few cases the specimens
had been entirely reduced to dust, nothing remaining to aid in identification
except the labels, while in other cases only fragments were left. Generally, however,
they were in fair condition, and now form a part of the herbarium of the Academy of
Natural Sciences, having been placed there on deposit by the Philosophical Society
shortly after their discovery. As might be expected, Pursh in his work of identification
had fallen into some errors, as a subsequent critical study of the collection by
Messrs, Robinson and Greenman of the Gray Herbarium demonstated; but nevertheless
fully one-half of the one hundred and twenty-three species referred to by Pursh
in the text of his Flora, stand as such to-day.

The collection has also been found to contain, in addition to these, a number of
species not recognized by Pursh as distinct, but which have proven to be the earliest
collections of many of the species of subsequent authors. That some of these, although
clearly quite new to Pursh, may have remained undescribed from what he
considered a lack of sufficiently perfect material, seems probable, as the following
quotation would indicate : "Here I cannot refrain from drawing the attention of
future botanists traveling in those regions to two highly interesting plants of which I
have only seen imperfect specimens. The first is what Mr. Lewis in his journal calls
the 'Osage Apple or Arrow wood of the Missouri.' "This plant is without doubt
the osage orange (Toxylon pomiferum, Raf.), a specimen of which, with no label, is
contained in the collection. Pursh, in continuation of the paragraph above quoted,
describes at considerable length the characteristics of the tree—or, as he terms it,
shrub—dwelling on its importance to the Indians in the making of arrows. He further
refers to specimens grown at Philadelphia from seed brought back by Lewis, considering
it in all respects a most desirable acquisition as an ornamental shrub; and yet,
with all this, he fails to give it a name. Three years after the date of the publication
of Pursh's Flora, the plant was described by Rafinesque under the name designated
above, he possibly drawing his descriptions largely from the specimens which originated
from Lewis's seed, planted twelve years before. Whether or not this be true
there seems but little doubt that the first information regarding the plant came
through Lewis.

The collection, as preserved in the Herbarium of the Academy of Natural Sciences
to-day, consists of specimens of one hundred and seventy-three recognizable species,
mostly in fair condition; these include fifty-five of Pursh's types recognized as species
at the present time, with thirty-eight additional ones, now for various reasons not considered
tenable. The number lacks but fifteen of the species referred to by Pursh as
contained in the Lewis Herbarium; of these, some may be included among the existing
specimens but, if so, are not recognizable from their descriptions.

In Pursh's Flora he describes but five new genera; of this number four are based
upon the plants received by him from Lewis, all of the specimens still existing in fairly
good condition.

Of these, three still retain the names conferred upon them by Pursh, two in honor
of the heads of the expedition—represented each by a single species : Lewisia rediviva
(Pursh Fl. 368), and Clarkia pulchella (Pursh Fl. 260, with an excellent figure);
and the third Calochortus, the genus of a handsome group of liliaceous plants confined
to the Western United States and Mexico.

The name selected by Pursh for the fourth new genus represented in the collection
had, unfortunately, been proposed as early as 1775 by Aublet for another plant,
which necessitated a new name. The discrepancy was noted by De Candolle, who
in 1817 in the transactions of the Linnean Society, the original medium of publication
of Pursh's new genera, renamed the genus in honor of Pursh, The species collected
by Lewis, which is represented by an excellent specimen, now bears the name of
Purshia tridentata (Pursh), D. C.

This Barton list is evidently made out from specimens collected when the numbers in the preceding
list were entered in Lewis's note-book, and agrees with this up to 40. Numbers 104 to 107 of
the Lewis list (p. 149, ante) are evidently to be matched off by lower numbers in the Barton list.
