Var. (1) Much more silvery and silky tlian usual, and with the racemes 

 nearly sessile ; approximating to the next and also much resembling what has 

 been called L. decumbens, Var. argophylla. Grass Valley and Regan's VaEey, 

 Western Nevada ; 5,000 feet altitude; June. (229.) 



LupiNUS MEIONANTHUS, Gray. Proc. Amer. Acad. 6. 522. Silvery- 

 canescent throughout ; stems ascending from a perennial root ; leaflets 5-9, 

 oblanceolate, obtuse; stipules small, setaceous ; bracts shorter than the calyx ; 

 flowers very small, (scarcely 3" long,) verticillate, in a crowded spike-like 

 raceme ; calyx longer than the pedicel, bractless, lips nearly entire, about equal 

 to the glabrous corolla ; keel with a broad obtuse apex, inflexed, cihate ; 

 legumes {l-V long) ovate, silky, 1-2-seeded. Near Carson City, (Anderson.) 



Var. (?) HETERANTHUS. Flowcrs somewhat larger, with the calyx gib- 

 bous or even spurred at base, and the lobes more elongated; legumes oblong, 

 3-5-seeded. Of exactly the habit of the last, with stems 1° high, the 

 racemes nearly sessile, and scarcely exceeding the leaves. Collected by 

 Anderson (92 and 232) and also by Dr. Torrey (88) in the same region with 

 the last, near Carson City. It would seem probable that this is the ordinary 

 form of the species, the other being but an abnormally small-flowered variety. 

 Washoe and West Humboldt Mountains, Nevada; 7,000 feet altitude; July- 

 September. (230.) 



LupiNUS CALCAKATUS, Kell. Proc. Cal. Acad. 2. 195, t. 60. Erect, 8-10' 

 high, silky-pubescent throughout, leafy; leaflets 7-10, linear-lanceolate, acute, 

 mucronate ; stipules ovate, acuminate, persistent ; flowers in a rather close and 

 short raceme ; bracts subulate, deciduous ; calyx deeply spurred at base, mi- 

 nutely bracteolate, the upper lip short, 2-toothed, white, the lower larger, 

 entire, acute ; banner and wings somewhat pubescent externally, and the keel 

 ciliate ; pods hairy, 4-seeded. — Flowers white, the spur exceeding the pedi- 

 cels. California (1891 Brewer) and near Carson City, (30 and 31 Anderson.) 



Lupmus LEUCOPSis, Agardh. Silky-tomentose, with whitish hairs ; leaflets 

 7-9, lanceolate, equaling the upper petioles; flowers somewhat verticillate in a 

 rather dense raceme ; vexillum silky-pubescent externally ; calyx-lobes nearly 

 equal, the upper 2-toothed ; legumes tomentose, 4-seeded. — Whole plant sil- 

 very, 2° high ; flowers light blue or ochroleucous. Collected by Douglas in 

 Oregon. In the Wahsatch, Utah; 6,000 feet altitude. (231.) 



Var. (?). Differing from the last in its somewhat broader leaflets, less
