Common St. John's-wort.

About a foot or eighteen inches high ; flowers as in all the
following species, yellow. This plant has become a most pes-
tiferous weed, every where throughout the Union. It is ac-
cused of injuring horses. Introduced originally from Europe.
In fields, and by road and fence sides, every where unfortu-
nately, abundant. Perennial. From June till August.

2. H. erect, very smooth ; leaves oblong ; pani-
cle naked, dichotomous; all the forks one-flow-
ered; styles coalescing, capsule globose. — Mich.

H. sphserocarpuin, Mich. ?

About ten or twelve inches high. Flowers pale-yellow,
small. This plant may not be the H. sphserocarpum of Mich.,
but it comes very near it; and for the present I have thought^
with Mr. Nuttall, that it had best be referred to that species.
On the borders of a ditch, surrounding a meadow on the east
side of the road to Woodbury, near the " canseivay" abun-
dant. I have found it no where else. It has also been found in
Jersey, by Mr. Collins. Perennial. June, July.

3. H. erect; stem four-angled, leaves oblong,
acute, narrowly sessile; panicle terminal, di-
chotomous; branches divaricate, with the flow-
ers arranged on them distantly alternate;

H. denticulatum, Walt.

Stem erect, simple ; from a span to twelve inches high,
four sided. Leaves from a quarter to a half-inch long-, and lit-
tle better than an eighth of an inch broad ; oblong-acute and
very closely sessile or semi-amplexicaule. Flowers the size of
those of No. 1, and of a fine fulvous or copper-colour. Up the
Delaware, eight miles from Philadelphia, rare ; Mr. Collins.
Perennial. June, July.

4. H. stem erect, ancipital immediately below each aiipressum.
pair of leaves, roundish towards the root. Leaves
opposite, closely sessile; lanceolate-obtuse, fine-
ly punctated with pellucid dots ; leaves of the
brandies numerous, crowded, sub-linear, ob-
tuse. Cymes crowded with small acute leaves;
flowers terminal and axillary, monogynous, pe-
tals obtuse, entire. Capsules sub-conoid. B.

Hypericum, No. 6. Bart. Prod. Fl. Phil. p. 74.

A very elegant species, from one foot to two and an half
feet high. The branches are divaricating, slender, appresssed
and frequently inflexed or curved downward, and crowded
with numerous leaves much narrower than the stem leaves,
less obtuse, and even inclining to acute. From the axills of the
stem leaves proceeds a cluster of five or six sub-linear obtuse
leaves, which appear to arise from abortive branches. The
flowers are yellow, about the size of those of No. 7. I disco-
vered this new species, about four years since, in a rich, wet,
or swampy meadow on the lower edge of Landsdown grounds,
.close to the Schuylkill, and not far above Breck's island. It
grows there in profusion, but I have not found it elsewhere.
It stands in my Prodromus, (No. 6.) without a name, not being
certain at the time I published that work, that it was unde-
scribed, although I could not find it to fit any of the described
species. Mr. Collins has also found this plant in this neigh-
bourhood. Perennial. July.

lanceolate calix. — Willd.

H. quinquenervium, Walt. Sp. PI. 3. p. 1456.

H. mutilum, Willd. Sp. PI. 3. p. 1471.

This species resembles No. 4, somewhat, particularly in the
size of the flowers ; but may easily be known by its leaves,
which are twice or thrice as broad as those of No. 4, and it
never has red capsules. In wet grassy places, and in company
with No. 4; also very common. Perennial. July till August.

, torymbosum, 7. H. erect, glabrous, dotted with black; stem te-
rete, branched; leaves amplcxicaule, oblong-

thickly flowered, calicine segments lanceolate-
acute. — Willd, and Fursh.

H. maculatum, Walt.

H. punctatum, Lamark.

Black spotted St. John's-wort.

About fourteen inches high; resembles No. 1, exceedingly,
but may be easily known from it by the numerous black punc-

Five-leaved Anemone.

A very delicate and handsome species, about six or seven
inches high, bearing a single blossom-red flower. This plant

Sacred-bean of India, Egyptian-bean.

There is not surely in North America any plant comparable
to this for grandeur, simplicity and beauty. Truly may it be
styled as I have elsewhere called it, the Queen of American
Floicevs. I regret to say that it is not as abundant in our vici-
nity as it was five years ago. This may be an accidental or
temporary decrease, owing to a disturbance of the site where
it grows. The leaves are perfectly round and centrally peltate.
They are from a foot to eighteen inches in diameter, of a rich
velvety -green above, and very pale underneath, They are sup-
ported by petioles from two, to three and a half feet in lengtli.
The flowers are pale-yellow, globose, and about three or four
inches in diameter, supported by petioles or a scape, a yard in
length, frequently muricate towards the upper part. From
this circumstance, together with an accurate examination of
a fine Chinese painting of the India species, which differed in
nothing from our plant, except in the rose-coloured flower,
Iconsideredthe two species as identical, and accordingly added
the synonyms which stand in my Prodromus. Another years*
examination of our plant has not given me reason to alter my
opinion on this subject, nor can 1 conceive that a mere differ-
ence in colour of the flowers should be considered sufficient
to establish the difference. Walter says his Nelumbo had
white flowers: so that even in our own country, a discrepancy
occurs here. I am glad to find that Mr. Nuttall has als» noticed
in his work, that the u peduncles are partly muricate."

of ground on the low wet margins of the Delaware, just above

dentally introduced in that neighbourhood, where at least it is

Does this plant differ from the one below, which I have quot-
ed on the authority of Mr. Nuttall ? The plant intended by me
referred to the above name, was considered by Dr. Muhlenberg
the Kalmii, and without any doubt. Mr. Nuttall makes this
different ; and as the plant has not flowered since I have seen

M0NADELPH1A, PENTANDRIA. 61

his work, I have consequently no opportunity of* examining
more accurately. The plant described by Mr. Nuttall as gra-
cilis, is the one so common in Jersey, and is the same intend-
ed by me in the present head. It appears to be Willdenow's
Kalmii, as it certainly is Muhlenberg's.

mostly hirsute; stem leaves remote, sessile,
scarcely ever exceeding an inch in length. Stem
filiform, often somewhat flexuous, but erect.

than a variety of P. alba, for I have met with hundreds of spe-

stantly presenting the same aspect and characters, and found it
in company with P. alba, which latter is always a much larger
plant, frequently attaining a height of six feet. On the border

Poor Robert's Plantane,

From eighteen inches to two feet high. Flowers (rays) pale-
purple. I have understood through Mr. Heckevvelder, (who
described the plant minutely) that this is one of the vegeta-
ble cures among the Indians, for the bite of the. rattle-snake.
Hence perhaps the name by which it stands in the herbarium
of Sir Joseph Banks, as quoted above. Though the name
Poor Robert's Plantane is sometimes applied to Hieracium ve-
nosum, yet the plant now under notice is much more com-
monly recognized by that appellation. As its congener Erige-
ron Philadelphicum, and E. heterophyllum are possessed of
active medicinal virtues, it is not unlikely that the remediate
powers attributed to this species by the Indians, are worthy
of attention. In shady woods and especially on hills, common.
Perennial. June, July.

Sweet Scabious. Various-leaved Flea-bane.

This species resembles Xo. 2, somewhat, in flowers and
habit. It differs however, strikingly, in its leaves, especially
the lower and radical ones. The general likeness of one to
the other, has caused them to be collected promiscuously for
medicinal purposes; thus accidentally leading me to ascertain
that this species is medicinal, like the preceding. (See Veg.
Mat. Med. U. S.) About three feet high. Flowers purplish
(rays). In cultivated fields with Xo. 2, but not so abundant.
Along water-courses, among grass ; frequent. Biennial. June,

all the grades of stature from two or three inches up to four
feet, I am rather inclined to suspect that it is a polymorphous
plant, assuming- all those different sizes and shapes, from the
influence of situation, soil, 8cc. It appears to be possessed of
medicinal properties. (See a paper in the Transactions of the
New-York Physico-Medical Society, by Dr. De Puy, vol. 1, p.

American Vallisneiia. Tape-grass, Channel-weed,
Duck-grass,

A very singular and interesting- aquatic plant, hardly more,
as Pursh correctly remarks, than a local variety of V. spiralis.
The peduncles of the female flower are always, more or less
spiral, particularly in deep water. Leaves three or five feet
long, and equal in breadth all their length — little more than
a quarter of an inch broad. In the Schuylkill, Delaware, and
ditches below the Navy -yard, common and abundant. This
plant grows in great abundance in the Susquehanna, and con-
stitutes the principal food of the Anas Vallisneria of Wilson,
(Anas ferina) or canvass-back duck ; and it is said to give the
food of that fowl its peculiar delicate flavour. Loose leaves,
peduncles and flowers of this plant, are frequently found
floating on the Delaware near the shores and among boats.

TETRANDRIA, MONOGYNIA.

To the genus Plantago,No. 80. vol. 1. p. 88, add
the following species :

4. Plantago hybrida; leaves subulate-linear, entire,
rigidly acute, shorter than the scape, not wool-
ly at the base; scape terete, slender, slightly
pubescent; spike long and slender, cylindrical,
rather loose; spikelets below, remote; bractes
acute. B.

Plantago maritima, Bart. Prod. Fl. Ph.

Root annual. Plant from two to three inches high, leaves
very numerous, about one inch long in mature specimens, often
not exceeding1 half an inch, destitute of any thing like wooli-
Jiess at the base. Scape slender, longer than the leaves, round
and slightly pubescent under a lens. Spike cylindrical, not ex-
ceeding one-eighth of an inch in diameter, from half an inch to
two inches long, and of a green and sienna colour, not deep
brown or blackish, as in the European and American speci-
mens of P. maritima. Scapes nearly as numerous as the leaves.
This species, which is decidedly distinct from the P. maritima,
I found four years ago, in the exsiccated canal on the road to
Lemon-hill, close to the high gravel banks. I there found it
two years in succession, and on transplanting it into my gar-

ADDENDA. 215

den it produced seeds which came up the succeeding- spring.
The mature specimens preserved the characters of the plant
as given above. I have before me a specimen of Plantago ma-
ritima, collected in Scotland by Dr. Edward Barton, and a
specimen of the same species collected in New England,
which I received from Mr. R. Griffiths, jr. These two plants
differ from each other some little, but as the P. maritina is said
to be a polymorphous species, the discrepancy is not of much
account. But from both the plant I have called hybrida above,
is strikingly and specifically distinct. Mr. Collins informs me
he has found specimens of the hybrida, in the same locality I
have identified above. Flowers in April, May.
