_ Y Stanleya arcuata sp. nov. 
Perennial with a ligneous caudex, 4-10 dm. high, perfectly 
glabrous ; stem light green and shining, in age straw-colored : leaves 
entire or the lower with short and broad lobes, lanceolate, long- 
petioled, thick, 5—12 cm. long ; pedicels rather short, in fruit, about 
1 cm. long: sepals yellow, linear about 15 mm. long; petals yel- 
low ; blades 7-8 mm. long, broadly elliptic, almost as long as or at 
least two thirds as long as the claw : pods 7-10 cm. long, strongly 
arcuate, and spreading. 
This species is nearest related to S. cntegrifolia, but is taller, 
more shrubby, with narrower leaves and broader petals. S. pin- 
nata (Pursh) Britton, with which both have been confused, has 
hairy leaves, most of which are deeply pinnatifid, and the blades 
of its petals are linear oblong and only one third or one half as 
long asthe claws. S. avcuata grows in dry regions from Wyoming 
to Nevada and south to Colorado and Arizona; probably also in 
California.

‘ Stanleya canescens sp. nov. 
Stout perennial .5—1 m. high; stem light green, finely puberu- 
lent or glabrate, terete : leaves grayish puberulent, the upper entire 
and oblanceolate, 5~7 cm. long; the lower pinnatifid with oblong 
lateral lobes and a large oval or elliptic end-lobe: raceme dense, 
pedicels short, in fruit 1 cm. or less long, divergent : sepals linear, 
about 12 mm. long ; blades of the yellow petals linear-oblong, about 
half as long as the claw: pods arcuate, spreading, 5-7 cm. long- 
This is nearest related to the preceding, differing in the puberu= | 
lent leaves, which are shorter and broader and more inclined tobe | 
pinnatifid.
