Sandy deserts, from the Great Falls of the Oregon to the sources of the
Missouri, Douglas ! Mr. Wyeth.—A very fine stout species, every part (save
the petals) clothed with compact very soft fulvous hairs ; the leaflets 2 inches
or more in length. Stipules subulate, longer than the bracts. Spike the
most dense of all the species, cylindrical, subsessile ; the flowers subsessile,
somewhat alternate. Upper lip of the calyx 2-cleft; the lower entire, very
obtuse. Corolla white, tinged with pink, rather longer than the calyx.—
This species, Dr. Lindley remarks, should rank next to L. alopecuroides, a
native of the Andes.
37. L. plumosus (Dougl.): densely villous with a silvery silky tomentum;
stem elongated; leaflets [5-7] lanceolate, rather longer than the petiole ;
flowers in an elongated dense spike ; bracts subulate-filiform, twice as long
as the flowers, caducous; calyx bracteolate ; vexillum silky-pubescent externally
; legumes glabrous. Agardh.—Dougl. ! in hot. reg. t. 1217 ,• Hoolc.

“ In North California, lat. 45°, growing in gravelly soil, at the source of
the Wallawallah River, near the Blue Mountains.” Douglas! (v. sp. in
herb. Lindl. Sf cult.)—Differs from the preceding in the more silvery downy
covering of the stem and leaves, the larger flowers in a much less crowded
spike, and in the much longer shaggy bracts, which give the unexpanded
portion of the raceme a comose appearance, &e. The leaflets are sometimes
as few as 3. Flowers white or rose-color.—In the dried specimens this species
seems quite distinct from D. leucophyllus, under which name it is, we
suspect, sometimes cultivated, as our specimens from the garden of the London
Horticultural Society are thus labelled. Indeed this name is more applicable
to this than to the former species, in which the down of the leaves,
as well as of the stem &c., is usually fulvous.
* * * Shrubby : stems decumbent or ascending, ligneous.
38. L. albifrons (Benth.): shrubby, decumbent, very densely silvery-
sericeous ; leaflets 7-9, obovate-euneiform, shorter than the petiole ; stipules
subulate ; flowers verticillate, with the whorls rather distant; bracts lanceolate,
acuminate ; calyx bracteolate ; the upper lip 2-cleft; the lower entire ;
corolla nearly glabrous. Agardh.—Benth. ! in hort. trans. 1. c. p. 410 ;

California, Douglas ! Nuttall!—Stems 8-12 inches long, very leafy below.
Leaflets obtuse, mucronulate. Peduncle elongated. Lips of the calyx
nearly equal. Corolla rather -large, blue : keel ciliate. Legumes silky,
4-5-seeded.
39. L. holosericeus (Nutt.! mss.): frutescent ? “ silvery-canesoent, low,
decumbent; leaflets 5-9, lanceolate, acute, narrowed at the base, arcuate,
densely silky-canescent and silvery on both sides, mostly shorter than the
petiole; stipules subulate; flowers verticillate or somewhat scattered, approximate,
small, on short pedicels; bracts lanceolate, shorter than the flowers
; calyx bracteolate ; the upper lip- slightly 2-cleft, the lower nearly the
same length and entire ; legumes silky, 3-4-seeded.”
Islands and gravelly banks of the Wahlamet, Nuttall!—Stem 6-8 inches
high, leafy, branching. Leaflets of the upper leaves as long as the petiole.
Flowers about half the size of those of L. albifrons, bright blue. Very
nearly allied to the preceding species, but with a marked difference in the
leaflets and size of the flowers : it does not agree with the more elongated
variety of that species with smaller flowers, mentioned by Agardh ; and it is
still more different from L. Douglasii. 40
40. L. Douglasii (Agardh): shrubby, densely silky and fulvous ; leaflets
oblong-lanceolate,, silky on both sides, attenuate at both ends, shorter than
the petiole ; stipules long, setaceous ; flowers irregularly verticillate ; bracts
subulate-filiform, longer than the flowers, caducous ; calyx bracteolate ; the
upper lip, almost 2-parted, the lower 3-toothed ; corolla nearly glabrous.

California, Douglas ! (v. sp. in herb. Lindl.)—The locality is omitted by
Agardh.
41. L. jlexuosus (Lindl.) : shrubby, ascending, silvery and silky ; stem very
flexuous ; leaflets obovate-oblong, silky on both sides, shorter than the petiole ;
stipules setaceous, minute (-'flowers in distant somewhat regular whorls;
bracts lanceolate, acuminate, longer than the flower buds, caducous ; calyx
bracteolate ; the upper lip somewhat 2-cleft, the lower entire ; vexillum
slightly sericeous. Agardh! 1. c. p. 34.
Oregon, Douglas! (v. sp. in kerb. Lindl.)—Flowers smaller than in L.
perennis, blue : keel ciliate.
42. L. littoralis (Dougl.) : shrubby, decumbent, silvery-sericeous; stem
filiform;'leaflets elongated-obovate, silky on both sides, shorter than the petiole
; flowers somewhat scattered ; calyx ebracteolate, both lips nearly entire
; corolla glabrous ; legumes 10-12-seeded. Agardh.—Dougl. ! in hot.

Rocky shores of Orégon from Cape Mendocino to Puget Sound, Douglas!
(v. sp. in herb. Lindl.)—Flowers pedicellate, purple ; the vexillum yellow
in the middle, with purple spots. Legumes nearly l i inch long.—The
granulated roots are farinaceous, and are used by the Chenook Indians as an
article of food, under the name of “ Somuchtan.” Dougl.
43. L. macrocarpus (Hook. & Arn.) : suffruticose, leafy ; leaves on short
petioles ; leaflets about 7, lanceolate, very obtuse, attenuate at the base, glabrous
above, silky with appressed hairs beneath ; raceme many-flowered ;
flowers (very large) rarely verticillate ; calyx, pedicels, and rachis silky ; legumes
linear-oblong, tumid, hirsute, 8-10-seeded. Hook. Sf Arn. hot.
Beechey, p. 138.
St., Francisco, California, Menzies.—“ This does not correspond with any
described species, nor with any found by Mr. Douglas. The lower part of
the stem is decidedly shrubby, the leaves and legumes large in proportion to
the size of the plant,, [and the flowers] apparently yellow when recent. Perhaps,
in habit, its nearest affinity is with L. littoralis, Dougl. ; but the leaves
are, in that plant, silky on both sides, the flowers differently colored, and the
legumes not half the size.” Hook. Sf Arn.
44. L. decumbens (Torr.) : suffruticose, rather decumbent, minutely silky-
pubescent ; leaflets about 7, oblong-lanceolate, glabrous above, somewhat
silky beneath, about the length of the petiole ; stipules subulate-setaceous,
minute ; racemes few-flowered ; the flowers scattered or somewhat verticillate,
on short pedicels ; calyx bracteolate ; the lips a little unequal, entire ;
legumes silky, 3-4-seeded.— Torr.,! in arm■ lyc. New York, 2. p. 191.
On the southern branches of the Arkansas, Dr. James !—Stems cæspitose.
Flowers smaller than in L. perennis, purple. Legumes about an inch
long.
