and roundish. Legume turgid, the valves ventricose-inflated. Seeds usually
several, compressed, reniform.—Herbaceous or shrubby plants. Leaves
simple or palmately compound. Flowers racemose, usually yellow. Brac-
teoles usually 1-2 at the base of the calyx.
The few North American species of this large genus are herbaceous, with sim.
pie leaves, few-flowered racemes opposite the leaves, and much inflated several-
seeded legumes, which turn blackish when fully ripe.
1. C. sagittalis (Linn.): annual, hairy; stem erect, branching; leaves
oval or oblong-lanceolate, scarcely petioled; stipules united and decurrent on
the stem, obversely sagittate ; peduncles rather short, about 3-flowered ; corolla
rather shorter than the calyx ; legume scarcely stipitate— Linn. ! spec.

Dry sandy banks and roadsides, Connecticut! and New York ! to_ Florida
! Louisiana! and Arkansas ! common. May-July.—Stem4 -8 inches,
or sometimes a foot or more in height, hirsute. Leaves 1-2 inches long, varying
from oval to lanceolate, pubescent with long soft hairs. Stipules of
nearly all, but especially of the upper leaves, large, the free portion triangular-
lanceolate ; occasionally the stipules are wholly wanting. Seeds_ small,
sinning, at length becoming loose and rattling in the parchment-like inflated
legume.—JRdttlebox.
2. C. Purshii (DC.) : perennial, minutely hirsute with short and stiff
much appressed hairs, or at length almost glabrous ; stems branching, erect;
leaves linear or linear-oblong, nearly sessile ; stipules narrowly decurrent,
the free portion subulate ; peduncles felongated, 3—7-flowered; corolla as long
as the calyx.—EC. 1. c. ? C. laevigata, Pursh l. c. ? not of Lain. C. par-
viflora, Pursh, l. c. ; Ell. l. c. ; EC. 1. c., not of Roth.
“ In damp or shady soils,” S. Carolina ! to Alabama ! Florida and Louisiana
! April-July.—Stem '8-18 inches high. Leaves 2-3 inches long,
linear and very narrow ; the lower ones shorter and broader, oblaiiceolate or
oblong, acute at the base. Peduncles often 6-8 inches in length. Flowers
about the size of those of the preceding .species.—The C. parviflora of Roth,
judging from his description, must be something different from this species,
and more probably belongs to C. sagittalis. This is, however, the C. parviflora
of Pursh (who has slightly altered the character of Willdenow), and of E lliott.
As to C. laevigata, Pursh, as well as the figure cited from Plukenet, we
are in doubt whether they do not belong to C. sagittalis : but the character of
C. Purshii is most probably drawn from the present species. The plant is
decidedly perennial. Should C. sagittalis prove to be sometimes perennial,
as is perhaps the case, no important character would remain to distinguish
the present species.
3. C. avails (Pursh) : perennial, hairy; stem's branching from_ the base,
diffuse, decumbent; leaves oval or elliptic, on very short but distinct petioles
; stipules small, those at the base of the branches usually larger and
decurrent, the others minute and subulate or often wanting; peduncles
elongated, 3-6-flowered; corolla as long as the calyx ; legume shortly stipitate.—

In dry barren soils, N. Carolina ! to Florida! and Louisiana! May-
July.—Root fusiform, long. Leaves about an inch long, roundish-oval, pubescent
with rather soft appressed hairs. Peduncles sometimes 6-10 inches
in length. Flowers rather larger than in C. sagittalis ; from which the species
is wholly distinct.

gen. Lupin. (1835.)
Calyx deeply bilabiate, often 2-bracteolate ; the upper lip 2-cleft or
toothed, or rarely entire ; the lower entire or 3-toothed. Yexillum with the
sides reflexed : wings foveolate-plicate towards the base, united at the summit
: keel falcate, acuminate. Stamens monadelphous ; the sheath entire :
alternate filaments longer: the 5 anthers opposite the sepals oblong and earlier
matured ; those- opposite the petals roundish or reniform and later. Stigma
bearded. Legume coriaceous, somewhat oblong, more or less compressed,
often torulose or intercepted with cellular partitions. Cotyledons fleshy.—
Herbaceous or rarely shrubby plants. Leaves palmately 5-15-foliolate, or
rarely reduced to. a single leaflet. Stipules either free or adnate to the
petiole. Flowers in terminal racemes or spikes.—Lupine.
§ 1* Annual: leaflets several: legumes more or less interrupted or constricted
between the seeds, dehiscent the following year.
* Legumes intercepted with cellular partitions between the seeds : cotyledons
thick and- large, sessile or nearly so in germination : primordial leaves
evident in the seed, opposite. Agardh.
+ Stem somewhat naked : spike elongated, with numerous flowers in regular
whorls : seeds elliptical, compressed, smooth. Agardh.
1 ■ L. Menziesii (Agardh) : flowers verticellate in a very long spike, pedicellate
; the pedicels about the length of the somewhat setaceous persistent
bracts ; calyx without bracteoles, the lips entire ; the . upper one scarious,
about half the length of the lower herbaceous one. Agardh ! sun. gen. Lupin.

2. L. miciocarpus (Suns) : flowers verticillate. in an elongated spike,
nearly sessile ; bracts subulate, persistent; about the length of the somewhat
2-cleft upper lip of the ebracteolate calyx, and about half the length of the 3-
toothed lower lip. Agardh— Sims, hot. mag. t. 2413 ; EC. prodr. 2. p. 408 ;

California, Eouglas /—This species is a native of Chili, and Agardh remarks
that he cannot distinguish the Californian specimens, except that the
flowers are perhaps a little smaller and the petioles longer. Leaves clustered
at the base of the stem. Stem about a foot high, and with the petioles and
lower surface of the leaves, a little villous. Calyx densely villous. Corolla
purplish-blue : vexillum yellowish in the centre, with purple spots. L egume
2-seeded.

sile ; bracts persistent, reflexed, about the length of the corolla ; calyx
