such exteriial characters as its elongated linear entire leaflets, taseicled 

 tubers, conspicuous involucels, prominent calyx-teeth, conical stylopodiuin, 

 and long recurved styles. Its nearest alliance Is to PimpineUa, from 

 which it differs, not only in most of the characters just noted, but also in 

 the concavity of the seed-face. The broad concavity of the seed-face, as 

 well as its comparative shallowness, is one of the marked cha'actersof 

 this genus, and separates it not only from certain allied genera, but also 

 from some specif s which have been confused with it. This cannot include 

 the Mexican forms I'eferred to it.
