380 LEGUMINOS^. Lupinus. 



Sandy deserts, from the Great Falls of the Oregon to the sources of the 

 Missouri, Doufrlas ! Mr. Wijeth. — A very fine stout species, every part (save 

 the petals) clothed with compact very soft fidvous hairs ; the leaflets 2 inches 

 or more in length. Stipules subulate, longer than the bracts. Spike the 

 most den-se 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 whh 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 ex- 

 ternally ; legumes glabrous. Agardh. — Davgi. ! in hot. reg. t. 1217 ; Hook. 

 I. c. ; Agarc/h ! I. c. p. 32. 



" In North California, lat. 45°, growing in gravelly soil, at the source of 

 the Wallawallali River, near the Blue Mountains." Douglas ' (v. sp. in 

 herb. Lindl. cy 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, &c. The leaflets are sometimes 

 as few as 3. Flowers white or rose-color. — In the dried specimens this spe- 

 cies seems quite distinct from L. leucophyllus, under which name it is, we 

 suspect, sometimes cultivated, as our specimens from the garden of the Lon- 

 don Horticultural Society are thus labelled. Indeed tliis name is more ap- 

 plicable to this tlian 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. alhifrons (Benth.) : shrubby, decumbent, very densely silvery- 

 sericeous ; leaflets 7-9, obovate-cuneiibrm, sliorter than the jietiole ; stipules 

 subulate ; flowers verticillate, with the whorls rather distant ; bracts lanceo- 

 late, acuminate ; calyx bracteolate ; the upper lip 2-cleft ; the lower entire ; 

 corolla nearly glabrous. Agardh. — Benth. ! in hort. trans, i. c. f. 410 ; 

 Lindl. ! hot. reg. t. 1642; Agardh! I. c. p. 33. 



California, Douglas ! Nuttall ! — Stems 8-12 inches long, very leafy below. 

 Leaflets obtuse, mucronulale. Pedurfcle elongated. Lips of the calyx 

 nearly equal. Corolla rather large, blue : keel ciliate. Legumes silky, 

 4-5-seeded. 



39. L. holosericeiis (Nutt. ! mss.) : frutescent ? " silvery-canescent, low, 

 decumbent ; leaflets 5-9, lanceolate, acute, narrowed at the base, arcuate, 

 densely silky-canescenl and silvery on both sides, mostly shorter than the 

 petiole ; stipules subulate ; flowers verticillate or somewhat scattered, ap- 

 proximate, small, on short pedicels; bracts lanceolate, shorter than the flow- 

 prs *, 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 indies 

 high, leafy, branching. Leaflets of the upper leaves as long as the petiole. 

 Flowers about lialf the size of those of L. alhifrons, 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 

 etill more different frona L. Douglasii. 



40. L. Douglasii (Agardh) : shrubby, densely silky and fulvous ; leaflets
