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 Londort- 

 Horticultural Society. Not having compared the two, wc are uncertain 

 whether it be the same with the fragment of L. argenteus preserved in Mr. 

 Lambert's herlnirinm ; nor are we well satisfied that the succeeding species 

 is distinct from it. 



28. L. ornalus (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 lanceo- 

 late, acuminate, scarcely longer than the pedicels, caducous ; calyx bracteo- 

 ■late ; vexillum silky-pubescent. Agardh. — Dougl. ! in hut. 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 herh. 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 en- 

 tire. 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 ; legimies tomentose. — 

 Agardh ! I. c. p. 29. 



Oregon, Douglas ! (v. sp. in herh. Lindl.) — Stem tall, branching, whitish 

 with a very dense tomeutum. Upper lip of the calyx 2-toothed ; the lower 

 entire, about the length of tlie upper. Corolla blue, larger than in L. peren- 

 nis. Legume 4-seeded. Agardh. 



30. L. alhicaulis (Dougl.) : fall, 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.— ifooA;. .' fl. Bor.-Am. 1. x>- 165 ; Agardh! I. c. p.^2Q. L. falci-

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 pe- 

 tiole ; stipules long and setaceous ; flowers somewhat verticillate in a dense 

 thick raceme ; bracts subulate, equalUug the ebracteolate 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 herh. 

 Lindl.) — Suftruticose ? Pedicels long. Calyx villous with yellow sUky 

 hairs ; the upper lip gibbous at the base, 2-toothed at the apex. Corolla yel- 

 low. Legumes very silky-villous. — This is said to be a very beautiful species.
