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 Caulanthus, 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. 
Chlorocrambe hastata (S. Wats.) Rydb. 
Caulanthus hastatus S. Wats. Bot. King’s Expl. 28. 1871. 
Sophia magna sp. nov. 
Annual ; stem branched, 5~ro 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 
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.

Slender annual ; stems 2-4 dm. high, slightly stellate or glab- 
rate ; leaves pinnatifid or bipinnatifid with linear or oblong divisions,

light-yellow, Spatulate, 1.5 mm, long ; fruiting pedicels ascending, 
4-6 mm. long; pods clavate, 5-8 mm. long, glabrous, slightly
