 2-valved. 



Bikukulla formosa (Andr.) Coville. Rootstocks thickish, creeping, the 

 leaves and scapes arising at the tips of the branches; leaves two or three times 

 ternate, 20-30 cm. broad, the ultimate segments pinnately incised into narrow 

 lobes, glaucous beneath; scapes exceeding the leaves; flowers bracted in 

 panicles; corolla rose-colored, cordate with short rounded spurs, the outer 

 petals with ovate spreading tips.

 keeled; stamens 6, in two sets, opposite the outer petals; pla- 

 centae 2; style entire, dilated or lobed; capsule oblong or linear, 

 2-valved. 



Capnoides scouleri (Hook.) Kuntze. Perennial from thickened roots; 

 stems scaly at base; basal leaves very large, pinnately decompound, the ulti- 

 mate segments oblong, obtuse, entire or the terminal ones 3-lobed, 3-5 cm. 

 long, glaucous beneath, blackening in drying; flowering stems with 1-3 smaller 

 leaves; flowers pale pink, in a loose raceme; corolla 2—3 cm. long, the spurs
