Francisco Mountains, 1871; Willow Spring, Ariz., Loew (1115); Rocky 
Caiion, Ariz., Rothrock (285). An apparently variable species of some- 
what uncertain limits. 
Lupryus FPARVIFLORUS, Nutt.—In the Sierra Nevada and northward to 
the Columbia, and also in the Wahsatch Mountains, where it was collected 
in 1871. 
Lupinus Laxirtorus, Dougl—From Washington Territory to Nevada 
and Utah; in the Wahsatch, 1871. 
LUPINUS ARGENTEUS, Pursh. ‘Perera. herbaceous, with short ap- 
pressed silky pubescence, the numerous stems rather low, leafy, much 
branched, often decumbent at base: leaflets 5 to 8, narrowly oblanceolate, 
smooth above or nearly so, equalling the short petioles: racemes nearly 
sessile, short: flowers small, blue or whitish, on slender, usually short 
pedicels: calyx broad, somewhat gibbous: petals naked or nearly so: pods 
3—5-seeded.—Oregon to Montana; at Mosquito Pass, Colo., Wolf (196). 
Var. DECUMBENS, Watson, /. c. 532, rather stout, with denser racemes, 
and var. ARGOPHYLLA, Watson, /. c., more silky-pubescent, and nearly equally 
so on both sides of the leaves, the flowers larger, and the calyx decidedly 
spurred, are both very common in the Rocky Mountains from Montana to 
New Mexico. The first was collected near Gray’s Peak by Wolf (197, 
202), at Rancheria Springs, Ariz., Loew (199), and at Sulphur Springs, 
Southern Arizona, Rothrock (543), the latter specimens closely approach-

the Sierra Nevada from Oregon to Southern Nevada and Utah, where it 
was collected in 1871. 
Lupinus LeEucopHyLius, Dougl—From Oregon to Utah and New 
Mexico; collected in the Wahsatch in 1871. 
Lupinus caspitosus, Nutt.—Perennial, dwarf, the stems very short and
