and quite decumbent; the stem is thick, hollow, striate and pubescent; the leaflets about

with a raceme of 15—25, purplish-blue flowers; shortly pedicellate, with a small bract 
at the base of the pedicel; calyx short, villous, with subulate teeth; vexillum and wings 
shorter than the keel: joints of the legume 3—4, nearly orbicular. 
"Prof. Torrey in Stansbury’s Report, p. 385, mentions H. Mackensii, (undoubtedly the 
same plant,) as found on Promontory Range of the Great Salt Lake. Mrs. Carrington’s 
plant appears so luxuriant and tender, that it will likely prove in cultivation a very valu- 
able food for cattle, as the generality of the sainfoins are. Great Salt Lake City, June Ist. 
Lupinus decumbens. Var. argophyllus, Gray, Pl. Fendl.,p.37. The whole plant clothed 
with short silvery hairs; leaves on long petioles; leaflets 6-—8, lanceolate acute, shghtly 
mucronate; peduncles longer than the leaves; raceme elongated; flowers rather small, 
» rose color mixed with purple. Mrs. Carrington. 
L. albicaulis, Dougl. in Torr. & Gr. fl. 1., p. 378. L. falcifer, Nutt. A larger species
