RyDBERG: Rocky MOUNTAIN FLORA 45 
cm. long, sparingly silky, short-strigose ; raceme 2-4 cm. long; 
bracts subulate, shorter than the buds ; calyx gibbous, silky with 
ers. It has also the peculiar hue and pubescence of that species, 
but it is a much smaller plant and of a different habit. The latter 
will place it near Z. Lyallu. It is an alpine plant growing at an 
altitude of 3000 m.

Lupinus scaposus 
Annual, with sessile clasping cotyledons ; stem branched at the 
base, I~1.5 cm, high, sparingly ciliate ; stipules lanceolate, acumi- 
Nate ; petioles 3-5 cm. long, ciliate, slender; leaflets about 7, 
Spatulate, 1 cm. long, sparingly silky-hirsute on both sides or 
glabrous above ; peduncles longer than the leaves, ciliate ; raceme 
Short, 1-4 cm. long ; bracts lanceolate, short; calyx ciliate, the 
lower lip broadly lanceolate, entire, 5 mm. long, the upper 2-cleft, 
ovate ; corolla purplish, 6 mm. long, paler at the base; banner 
Shorter than the wings ; legume ciliate, 1 cm. long, 6 mm. wide, 
2-seeded. 
In habit mostly resembling L. drevicaulis but more evidently 
caulescent, with longer peduncles. The most distinctive char- 
acters, however, are the different calyx and its entire lower lip. 
This associates it with J. pusillus, from which it differs in the long 
Peduncles and smaller flowers.
