RANUNCULACEAE (CROWFOOT FAMILY) 167 
curarin, has been extracted from both 
these species. (Fig. 113.) 
The plant springs from a cluster of 
thickish, oblong tubers, fringed with fine 
feeding rootlets. Stem simple, slender, 
often bent or flexuous, both it and the 
foliage finely hairy; the lower leaves 
have long petioles, slightly dilated at 
base, and are deeply five-parted, the 
segments again twice or thrice divided; 
the upper leaves are small, oftenest of 
three nearly linear segments. Raceme 
terminal, slender, the flowers few, on 
long, nearly erect pedicels; they are large 
and showy, deep violet-blue, the sepals 
and the spurs nearly equal in length, 
bearded outside; the two upper petals 
are yellowish but are distinguishable 
from D. bicolor because they are not 
net-veined. Follicles three, widely re- 
curving at maturity, the seeds black and 
winged on the outer angles. 
Means of control the same as for Del- 
phinium bicolor.

somewhat kidney-shaped at base, the segments wedge-shaped and 
deeply cut and lobed at the tips. Racemes large and loose, often
