436 Rydberg : Rocky Mountain flora 



base, linear-oblong, at last curved, greenish. Pod slender, some- 

 what torulose, short-stipitate and short-styled ; stigma minute, 

 entire. 



The plant referred here has been included in Canlantlnis, but 

 the type of that genus, C. crassicaulis, and its allies have an urn- 

 shaped, more or less closed calyx ; linear, oblong, or spatulate 

 petals, which have practically no claws, are thin and membranous 

 except the upper third or fourth, which is thicker, brownish or 

 purplish, curved and crisp ; and a conspicuous, two-cleft stigma.

Sophia magna sp. nov. 



Annual ; stem branched, 5-10 dm. high, sparingly stellate- 

 puberulent or glabrous, stout ; basal leaves twice to thrice pin- 

 natifid, 1—2 dm. long, nearly glabrous ; segments obovate, often 

 toothed ; stem-leaves similar but with narrower segments ; sepals 

 yellow, 2 mm. long, oblong ; petals spatulate, nearly 3 mm. long, 

 rather light-yellow ; pedicels in fruit i 5—20 mm. long, ascending ; 

 pod glabrous, more or less clavate, 12—15 mm. long, 1.5-2 mm. 

 thick ; seeds more or less in two rows. 



This species is related to 5. intermedia and S Jilipes, but differs 

 from both in the broad segments of the basal leaves. In habit it 

 therefore resembles J^. incisa, but has an evidently clavate pod. It 

 has the conspicuous flowers of S. Jilipes, but the terminal segment 

 of the leaves is not elongated. It was first mistaken for S. hracJiy- 

 carpa ; but the style is evident although short. It grown on river- 

 bluffs at an attitude of 1500—2500 m.

Sophia Nelsonii sp. nov. 



Slender annual ; stems 2—4 dm. high, slightly stellate or glab- 

 rate ; leaves pinnatifid or bipinnatifid with linear or oblong divisions, 

 slightly stellate or glabrate ; sepals oblong, i mm. long ; petals 

 light-yellow, spatulate, 1.5 mm. long ; fruiting pedicels ascending, 

 4-6 mm. long ; pods clavate, 5—8 mm. long, glabrous, slightly 

 over I mm. thick ; style minute. 



This species is probably nearest related to 5'. intennedia, but
