mose. Flowers as large as in L. hirsutus. Upper lip of the calyx cleft at
the apex; the lower entire, scarcely longer.” Agardh.—The description of
Agardh is drawn from a specimen cultivated in the garden of the London
Horticultural. Society. Not having compared the two, we are uncertain
whether it be the same with the fragment of L. argenteus preserved in Mr.
Lambert’s herbarium ; nor are we well satisfied that the succeeding species
is distinct from it.
28. L. ornatus (Dougl.) : tall, silvery-sericeous; leaflets 7-11, obovate-
linear, silky on both sides, half the length of the petiole ; stipules subulate ;
flowers verticillate in an elongated raceme, the whorls distant; bracts lanceolate,
acuminate, scarcely longer than the pedicels, caducous ; calyx bracteo-
late ; vexillum silky-pubescent. Agardh.—Dougl.! in hot. reg. t. 1216;

Near the source of the Oregon ; also at Kettle Falls, and in the vallies of
the Spokan River, Douglas! (v. sp. in herl. Lindl.)—Stem 1-3 feet high.
Leaflets clothed with a close appressed hirsute silvery pubescence. Upper
lip of the calyx cleft at the apex ; the lower a little longer, obtuse, nearly entire.
Corolla blue, as large as in L. perennis, twice the length of the calyx.
—We doubt if the succeeding species .be sufficiently distinct from this,
in which the leaflets are sometimes about the length of the petiole.
29. L. leucopsis (Agardh) : silky-tomentose with whitish hairs ; leaflets
7-9, lanceolate, as long as the petiole; stipules subulate, short; flowers
somewhat verticillate in a rather dense raceme ; bracts very caducous ; calyx
bracteolate ; vexillum silky-pubescent on the outside ; legumes tomentose.—

Oregon, Douglas ! (v. sp. in herb. Lindl.)—Stem tall, branching, whitish
with a very dense tomentum. Upper lip of the calyx 2-toothed ; the lower
entire, about the length of the upper. Corolla blue, larger than in L. perennis.
Legume 4-seeded. Agardh.
30. L. albicaulis (Dougl.) : tall, puberulent ; stem somewhat persistent;
leaflets 7-9, oblanceolate, mucronate, minutely silky-puberulent on both
sides; about the length of the petiole; stipules minute, caducous; flowers
somewhat verticillate or scattered, in a long dense raceme ; bracts subulate,
deciduous, about the length of the downy pedicels ; calyx silky ; the lips
elongated, nearly equal, the upper 2-cleft at the tip ; keel elongated, falcate,
glabrous.—HooJc.! Jl. Bor.-Am. 1. p. 165 ; Agardh! 1. c. p. 29. L. falci-
fer, Nutt.! mss.
Oregon, about Fort Vancouver, common, Douglas! Nuttall!—A large
showy species, with a long raceme of purple flowers, well distinguished by
its long curved keel. Mr. Nuttall’s specimens wholly agree with those of
Douglas ; but the bracts are by no means persistent, as described by
Agardh, &c.
31. L. Sabinii (Dougl.) : stem tall, striate, nearly glabrous ; leaflets 8-11,
lanceolate, silky on both sides with fulvous hairs, rather longer than the petiole
; stipules long and setaceous; flowers somewhat verticillate in a dense
thick raceme ; bracts subulate, equalling the ©bracteolate calyx ; keel ciliate.

On the Blue Mountains, Oregon ; and on the dividing ridge of the Rocky
Mountains, near the confines of perpetual snow, Douglas ! (v. sp. in herb.
Lindl.)—SufTruticose ? Pedicels long. Calyx villous with -yellow silky
hairs; the upper lip gibbous at the base, 2-toothed at the apex. Corolla yellow.
Legumes very silky-villous.—This is said to be a very beautiful species. 32
32. L. sulphurous (Dougl.): stem erect, sulcate, silky; leaflets 13-15,

narrowly lanceolate, densely sericeous on both sides, shorter than the petiole;
stipules subulate, short; flowers somewhat verticillate in a dense thick raceme
; calyx ebracteolate ; keel glabrous. Agardh.—Hook. Jl. Bar.-Am. 1.

' On the Blue Mountains of Oregon, and near the source of Clarke’s River,
Douglas ! (v. sp. in herb. Lindl.)—This is said to resemble the foregoing, but
is a much slenderer and smaller plant, the leaflets (whitish) narrower and
more numerous, the flowers smaller and of a pale sulphur-color. Calyx
very silky.
33. L. sericeus (Pursh): silky-villous; leaflets 7-9, lanceolate, narrowed
at the base, rather longer than the petiole ; stipules minute, setaceous ; flowers
somewhat verticillate in an elongated raceme ; bracts about the length of
the flower-buds ; calyx bracteolate ; corolla glabrous. Agardh.—Pursh. Jl.

Banks of the Kooskoosky River, Lewis. Oregon ? Douglas ! On the
Flat-Head River and in the Rocky Mountains, Nuttall! Also in California?
—Corolla rose-color or pale purple, according to Pursh; blue, according to
Nuttall.—Fischer and Meyer remark that the L. sericeus of Eschscholtz is
the same with their L. arboreus /?. odoratissimus, which is probably L. rivu-
laris ; while they refer the L. sericeus of Hooker and Arnott to L. Chamissonis,
Esch.' We have not the means of ascertaining by comparison whether
the Californian species has been correctly referred to L. sericeus of Pursh.
34. L. caspitosus (Nutt. ! mss.) : “ dwarf, nearly'stemless, silky-hirsute ;
leaflets 5—7, oblong-lanceolate, attenuate at the base, much shorter than the
petiole ; spike sessile, densely-flowered, much shorter than the leaves ; bracts
setaceous, deciduous; calyx bracteolate, the upper lip 2-parted, the lower
obscurely 3-toothed; legume villous, 3-4-seeded.
“ In the grassy vallies of the Rocky Mountains, on the Sweet Water of the
Platte and the Colorado of the West.—Plant 3—4 inches high, forming small
csespitose tufts. Stipules adnate, subulate. Flowers small, nearly sessile,
pale blue. Nuttall.”—Allied to L. aridus, Dougl., but the flowers are smaller,
the keel naked, &c. It also resembles L. pusillus.
35. L. aridus (Dougl.) : very silky-hirsute with fulvous hairs ; stem low
much branched from the base ; leaflets 7, oblong-lanceolate, about one-third
the length of the petiole ; flowers in a conical very dense spike ; bracts subulate,
rather persistent, shorter than the bracteolate calyx ; vexillum glabrous •
keel lanuginous-ciliate ; legumes villous. Agardh.—Dougl. ! in bot. res. t.

Dry sandy deserts of the Oregon, from the Great Falls to the sources of
the Missouri, Douglas ! (v. sp. in herb. Lindl.)—Stem scarcely a foot high.
Stipules subulate. Flowers irregularly verticillate, on short pedicels rose-
eolor. Upper lip of the calyx 2-cleft, the lower entire. Corolla about one-
third longer than the calyx. Agardh.
, leucophyllus (Lindl.) : densely villous with a fulvous silky tomentum
; stem elongated; leaflets 7-9, linear-lanceolate or lanceolate-oblong'
acuminate, shorter than the petiole ; flowers crowded in an elongated very
dense subsessile spike ; bracts somewhat persistent, shorter than the expanded
