Sound! to Oregon! and California: also around the shores of the Great
Lakes! and along the rivers, &c. to the shores of the Arctic Sea (Richardson).
May-July.—The whole plant has a somewhat glaucous aspect, and
much the habit of a Pea. The leaflets (often scattered) are commonly from
1J to 2 inches in length, and £-1 inch wide, with reticulated veins ; in shady
situations the stem is more slender, less leafy, and the leaflets rather smaller.
Stipules usually toothed below, cordate-hastate, the lower angle or lobe acute,
often more or less inequilateral. Peduncles 6-10-flowered. Flowers large
and showy, purple; the wings and keel paler. Lower segment of the calyx
linear, a little narrower, and slightly exceeding the lateral ones. The specimens
from Arctic America are smaller and fewer-flowered.—Our specimen
of L. pisiformis from Altaic Siberia, communicated by Prof. Fischer, differs
from our various forms of the plant above described in having a narrowly
winged stem, much larger and semisagittate stipules, and somewhat ovate-
oblong leaflets. We perceive no other difference of any importance; but, as
these may be expected to prove nearly constant, we have thought it best to
retain the specific name of Bigelow for the present, since our plant is doubtless
the same as the Pisum maritimum of the North of Europe.
3. L. polyphyllus (Nutt.! mss.): “ glabrous; stem nearly erect; angled,
leaflets 5-8 pairs, oval-oblong, obtusish, the tendrils very short; stipules as
large as the leaflets, semicordate, angularly crenate at the base, sometimes
acuminate; peduncles 7-10-flowered; shorter than the leavessegments of
the calyx hairy on the margin, the two upper ones triangular and much
shorter than the lanceolate lateral ones, the inferior one subulate-setaceous,
rather longest; corolla purple ; legume smooth, acuminated, long and flat.
“ ji. angles of the stem acute ; stipules broadly semisagittate.
“ Forests of the Oregon to the se a ; in shady places.—Stem about 2 feet
high. Leaflets 1J inch long, and half an inch or more wide. Flowers rather
large.—Considerably allied to L. pulchellus of Altai, but with more flowers
on the peduncle.” Yw££.lb-This plant is probably included by Hooker
among the “more lax and flaccid forms of L. pisiformis "apparently inhabiting
woody d is tr ic ts a n d we should incline to take the same view of i t ;
but the setaceous inferior segment of the calyx, and the rather shorter superior
teeth will perhaps prove a constant distinction.
4. L. venosus (Muhl.) : glabrous or somewhat pubescent; stem erect or
reclined, strongly 4-angled ; leaflets 5-7 pairs, ovate-oblong or broadly ovate-
elliptical, obtuse; stipules very small, lanceolate or oval, semisagittate (the
deflexedlobe about as long as the superior portion) ; peduncles many- (8-16-)
flowered, rather shorter than the leaves; calyx pubescent or nearly glabrous;
the 2 upper segments very broad and short (not half the length of the lateral
ones) ; corolla purple ; legumes linear-oblong, compressed.—Muhl. in Willd.

katchawan, (Richardson, Drummond) to the shore of Lake Superior, Dr.
Houghton! and Illinois, ex Nuttall: also N. W. Coast and California, ex
Hooker. &. Bushy woods of the Oregon, Nuttall! June—July. Stem about
3-4-angled and striate, 2-3 feet high. Petioles channelled above. Leaflets
in a. & y. about 1J-2 inches long; in 0. larger, somewhat conspicuously reticulate
veined above when old. Flowers smaller than in the two preceding
species, racemose, crowded. Lateral segments of the calyx triangular-lanceolate,
a little shorter than the somewhat narrower lower segment; the
upper ones broadly triangular and extremely short.—A widely diffused species,
if we are correct in joining with it the L. decaphyllus of Hooker, &e ,
readily distinguished by its very small stipules, These are however a little
variable in the ordinary form, even in the same specimen; the upper ones
being often larger and broader.
5. L. ochroleucus (Hook.): glabrous, pale and a little glaucous; stem slender;
leaflets about 3 pairs, broadly oval or ovate; stipules semicordate;
smaller than the leaflets, entire or obtusely toothed below ; peduncles 7-10-
flowered, shorter than the leaves; calyx somewhat truncate above ; the upper
segments broadly triangular, scarcely half the length of the oblong lateral
ones; the lower lanceolate and a little longest; corolla yellowish-white; legumes
linear-oblong, compressed, glabrous.—Hook.! fl. Bor .-Am. 1. p. 159 ;

Shady hill-sides and banks of streams &c., from the Arctic circle, Dr.
Richardson! (Bear Lake) to the Western and Northern part of New-
York! and New Jersey! June-July—A smaller and more delicate plant
than the preceding, straggling or somewhat climbing. Leaflets 1-14 inch
in length, thin and membranaceous. Stipules either rounded at the base, or
with an acute angle, somewhat variable in siz e; the lower ones considerably
smaller than the leaflets ; the uppermost often nearly their size, particularly
in the subarctic forms. In the latter, also, the peduncles are nearly as long
as the leaves. Segments of the calyx minutely hairy on the margin. Flowers
about as large as in L. venosus.
6. L. myrtifolius (Muhl.) : glabrous ; stem slender, acutely quadrangular
and often slightly winged ; leaflets 2-3 pairs, oval-elliptical or oblong, obtuse
at each end; stipules ovate-semisagittate, smaller than the leaflets, nearly
entire; peduncles 3- 6-flowered, longer than the leaves ; upper segments of
tire calyx broad and shortest, the others triangular-lanceolate; corolla pale
purple (the wings and keel, whitish); legumes (immature) oblong-linear,
compressed, glabrous.—Muhl. in Willd. sp. 3. p. 1091; Pursh, ft. 2. p. 471;

July-Aug.—More or less climbing. Stem 2 -4 feet long. Flowers the
size of the preceding.—We have drawn up the character from the ordinary
and well-marked forms of this species; but we have varieties which so nearly
approach to L. palustris that we are unable to point out any certain and constant
mark of distinction. The leaflets are ordinarily an inch and a half in
length and about half an inch wide, veiny, and rather rigid. The stipules
are extremely variable in size, being sometimes half the size of the leaflets,
but often (especially the lowermost) very small: their base is sometimes
rounded and sometimes acute. We have not seen the ripe fruit.
7. L. palustris (Linn.): mostly glabrous ; stems somewhat erect, winged;
leaflets 3 pairs, oblong-laneeolate, obtusish, mucronate, rather rigid; stipules
very small, lanceolate, semisagittate, acuminate, the deflexed lobe also acumi
