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 I1-1.5 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 
eid 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. 
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-floccose; stem 1 dm. high or less; sepals densely 
villous, 3 mm. long, ovate, acute; petals white, clawed; blades 
rounded-obovate; pod glabrous, about 5-6 mm. long, oblanceolate, 
tapering at the base; style very short. 
This species has the pubescence of .S. ovata, but the pod is taper- 
ing at the base. It has whiter and longer pubescence than 5. 
americana, and the pod is much shorter. It differs from both in 
the shape of the earlier leaves.
