RYDBERG: STUDIES ON THE: RocKy MounTAIN FLora 289 
line, 3-10 cm. long, twice pinnatifid, densely pubescent ; primary 
divisions of the lower leaves ovate and obtuse ; those of the upper 
lanceolaté and acute; secondary divisions oblong acute or obtuse, 
often few-toothed : inflorescence usually much branched ; pedicels 
in fruit 8-12 mm. long : sepals yellowish, 1-15 mm. long, oblong ; 
petals bright yellow, spatulate, about 2 mm. long: pod (in the 
specimens seen not fully developed) over 1 cm. long and less than 
I mm. wide: seeds uniserial. 
This is perhaps nearest related to S. incisa (Engelm.) Greene ; 
but differs in the dense viscid pubescence of the stem, the pubescent 
leaves and deeper divided primary segments. It grows among 
rocks and on grassy slopes.

~ Sophia leptophylla sp. nov. 
Stems 5-7 dm. high, sparingly glandular: leaves very thin, 
dark green, only once pinnate; segments of the lowest leaves 
rounded ; those of the middle lanceolate and somewhat incised ; 
the upper segments entire : pedicels slender, in fruit 5-8 mm. long, 
spreading : petals bright yellow, about 1.5 mm. long: pod linear, 
- 8-10 mm, long, much less than 1 mm. wide, torulose, spreading, 
arcuate, curved up, uniserial. 
This is nearest related to S. incisa (Engelm.) Greene, but differs 
in the less incised leaves and horizontal curved pod. It grows at 
an altitude of about 2000 m.
