RvDBERG : Studies on the Rocky Mountain Flora 244 



brous, 8-12 mm. long : peduncles very slender, about 5 cm. long: 

 inflorescence cymose, but often reduced to 2-3 flowers ; pedicels 

 sparingly strigose : sepals 4—5 mm. long, oblong : petals yellow, 

 6-7 mm. long: pod cylindric with a conical apex, 12—15 ninn. 

 long, 2.5-3 nim. wide, glabrous. 



This is nearest related to 0. cymosa Small and O. Brittoiiiac, 

 but differs from the former in the blunter sepals, the appressed 

 pubescence of the pedicels and the glabrous pod, and from the 

 latter in the simpler habit, the longer glabrous pod and paler and 

 larger leaves. It grows in grassy valleys at an altitude of 1800— 

 2500 m.

Lupinus Scheuberae sp. nov. 



Perennial ; stem 4—6 dm. high, sparingly strigose or almost 

 glabrous, slender : petioles of basal leaves about i dm. long ; leaf- 

 lets 7—8, oblanceolate, 5-7 cm. long, acute and mucronate, green, 

 glabrous above, sparingly appressed pubescent beneath ; stipules 

 lanceolate, attenuate ; stem leaves similar but shorter petioled : 

 racemes i — 1.5 dm. long, not dense; bracts lanceolate, 7—8 mm. 

 long, deciduous : flowers 10-12 mm. long: calyx densely white 

 silvery puberulent, strongly gibbous above ; lower lip lanceolate, 

 fully twice as long as the triangular-ovate upper lip : corolla dark 

 purple but lighter and almost white towards the base ; banner 

 slightly longer than the wings, silky puberulent on the middle of the 

 back : pod densely white silky with appressed hairs, 2-4-seeded. 



This is nearest related to L. psaidoparviflonis, but differs in the 

 somewhat larger flowers, the strictly appressed white pubescence 

 on the calyx and pedicels, the gibbous, but not spurred calyx, and 

 the broad and short upper lip of the latter. It grows in woods at 

 an altitude of 2,000-2,400 mm.
