160 RypperG: Srupres oN THE Rocky Mounrain FLorA 
leaf-blades and smaller flowers. It resembles still more the Euro- 
pean P. Pyrenaicum, which has larger petals, 1-2 cm. long, sta- 
mens much exceeding the ovary and spherical flower-buds.

Argemone rotundata 
Stem stout, densely and strongly bristly, but otherwise gla- 
brous : leaves oval in outline ; the cauline ones sessile and broadly 
auricled, bristly, especially on the veins and margins, round-lobed : 
flowers short-pedicelled or subsessile : calyx very bristly ; its horns 
erect or slightly spreading, bristly : petals white, fully 4 cm. long: 
pod ovoid, very bristly. 
This has been mistaken for A. /ispida Gray but is perhaps 
nearer related to A. intermedia and A. platyceras. From A. hispida 
-it is easily distinguished by the absence of a finer indumentum and 
by the round-lobed leaves. The latter character also distinguishes 
it from the other two species mentioned. It is also much more 
bristly than the two. It grows at an altitude of 1500-1800 m.

v Bicuculla occidentalis 
Perennial with a very short rootstock bearing numerous tubers : 
scape and leaves perfectly glabrous; petioles of about 1.5 dm. 
long ; blades twice ternate ; the divisions twice pinnately divided 
or cleft into linear-oblong lobes, 1-2 cm. long, 3-5 mm. wide: . 
scape about 3 dm. high: raceme simple: sepals oval, about 5 mm. 
long: petals pink ; the outer about 1 cm. long; their spurs en 
12 mm., divergent, forming with each other an angle of 90° °F 
more; crest of the inner petals prominent ; capsule fusiform, with 
the style about 1.5 cm. long. 
This is nearest related to B. cucullaria, and has been confused 
with it, but has coarser foliage, more diverging and longer spUr, 
more prominent crest on the inner petals and the underground parts 
more gruinose and not scaly. Its range includes parts of Oe 
Washington and eastern Idaho, and it grows on shaded hillsides.
