Rydberg: Studies on the Rocky Mountain flora 327 



Perennial with a stout caudex; leaves basal, runcinate, more or 

 less glandular-hirsutulous, thick, 6-8 cm. long, oblanceolate in 

 outline; scape 1-1.5 dm. long, glandular-hirsutulous; sepals ob- 

 long, 8 mm. long, saccate at the base; petals 15-18 mm. long, 

 purplish; claws long, exceeding the sepals; blades obovate; fruit- 

 ing pedicels 8-15 mm. long, ascending; pod erect, glandular-his- 

 pidulous, 3-4 cm. long, 6-7 mm. wide, acute at both ends, slightly 

 constricted between the seeds, these broadly winged, 3-4 mm. 

 wide. 



This is characterized by its deeply lobed leaves, the hispidulous 

 pubescence, the broad hispidulous pod, and the longer narrow 

 petals with slender claws.

Smelowskia lobata sp. nov. 



A densely cespitose perennial; earlier basal leaves cuneate or 

 oblanceolate, merely lobed, with oblong divisions or even some 

 of the earliest entire; the rest of the leaves pinnatifid, densely 

 white stellate-fioccose; stem i dm. high or less; sepals densely 

 villous, 3 mm. long, ovate, acute; petals white, clawed; blades 

 rounded-obovate; pod glabrous, about 56 mm. long, oblanceolate, 

 tapering at the base; style very short. 



This species has the pubescence of 5. ovata, but the pod is taper- 

 ing at the base. It has whiter and longer pubescence than ^S". 

 americana, and the pod is much shorter. It differs from both in 

 the shape of the earlier leaves.

 This has been confused with D. andina Nutt. and D. densiflora 

 Nutt., but it is easily distinguished by the lea^■es. They are 

 scarcely stellate-pubescent, merely strongly ciliate on the margins 

 and with an incurved tip. In the other two species the leaves
