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 Cau/anthus, 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 15-20 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 S. intermedia and S /filipes, but differs 
from both in the broad segments of the basal leaves. In habit it 
therefore resembles S. zzcisa, but has an evidently clavate pod. It 
has the conspicuous flowers of S. filipes, but the terminal segment 
of the leaves is not elongated. It was first mistaken for S. brachy- 
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 biabeet "> 
slightly stellate or glabrate ; sepals oblong, 1 mm. long; pet / é 
light-yellow, spatulate, 1.5 mm. long ; fruiting pedicels nace 
4-6 mm. long; pods clavate, 5-8 mm. long, glabrous, slightly 
_ over I mm. thick ; style minute. : 
‘his species is probably nearest related to S. intermedia, but .
