LupiNUS POLYPHYLLus, Lindl. (?) Specimens from Dr. Anderson (46) 

 near Carson City, Dr. Torrey, (83 and 83 a, ) from Washoe and Donner Lakes, 

 and from Burke in Southern Idaho, may belong to this species, but are more 

 probably distinct. Stems slender, 1-2° high, branching, sparingly pubes- 

 cent; leaflets 7-9, oblanceolate, about equaling the petioles, (2-3' long, 

 4-6" wide,) acute, glabrous above, subpubescent beneath; racemes loose, 

 6-12' long; bracts setaceous, hairy; flowers subverticiUate ; lips of the 

 calyx nearly equal in length, somewhat silky, nearly entire ; petals equal, 

 5" long, the keel nearly semicircular; legumes rufous-hairy, 7-9-seeded, 

 16" long, 3-4" broad. 



LupiNus 1.AXIFL0EUS, Dougl. Stem minutely silky-puberulent ; leaflets 

 7-9, (rarely 11,) linear-oblong, rather obtuse and mucronate, silky-pubescent 

 both sides ; flowers scattered or a little verticillate, in a loose elongated raceme ; 

 upper lip of calyx saccate at base, minutely 2-toothed at the apex, the lower 

 entire ; legumes silky, 2-5-seeded.^Stems 2° high; flowers blue or ochroleu- 

 cous. According exactly with authentic specimens in Herb. Gray. It appears 

 to have been collected only in the mountains of Oregon. Found in the East 

 Humboldt Mountains, Nevada ; 7,500 feet altitude ; July. (226) 



LupiNTJS AEGEN.TEUS, Pursh. (Including L. laxiflorus, Yav.foliosus, T. & Gr.) 

 Distinguished from the last only by the less saccate calyx and the somewhat 

 smoother or even glabrous upper surface of the leaflets. Some of the speci- 

 mens are of this character, but others seem to unite the two species, and leave 

 httle doubt that they must be reduced to one. Clover Mountains, Nevada, 

 and Wahsatch Mountains, Utah; 5,000 feet altitude. (227.) 



LtrpiNUS fLexuosus, Lindl. "Shrubby" (I), ascending, silvery-silky; 

 stems veryflexuous; leaflets obovate-oblong, shorter than the petiole; flowers 

 in distant, somewhat regular whorls ; upper hp of calyx somewhat 2-cleft, the 

 lower entire ; banner slightly silky ; keel cihate. — The plants accord with 

 authentic specimens in Herb. Gray, but are not at all shrubby, and more 

 frequently rather villous than silky. It is the most prevalent lupine of 

 Nevada, the early spring forms frequently very villous ; stems 1-2° high, 

 flowers blue, occasionally ochroleucous. Reported only from Oregon. 

 Frequent in the valleys and mountains of Nevada; 5-9,000 feet altitude; 

 April-August. (228.)
