Type, sheet no. 252762 in the herbarium of the U. S. National 
Museum. 
The sheet bears the determination “J. seroténa R. & S.,” 
but that is according to Choisy a species of Quamoclit (Q. mu- 
fica), and the original description of /. sevotzna describes the 
pedicels as shorter than the leaves, which is not the case in the 
species here described.
