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.
