The East Indian species which Nees von Esenbeck considered 
identical with Vahl's Barleria bispinosa is quite distinct from 
the Abyssinian specimens, which are certainly Vahl's plant. 
The East Indian species has greater affinities with B. buxifolia, 
Linn. than with B. bispinosa, Vahl. As I consider the East 
Indian and Ceylon plants, named by Nees von Esenbeck B. 
bispinosa and B. spina Ceylanica, to be one species, I propose to 
adopt the latter specific name, while I retain B. bispinosa, Vahl, 
for the Abyssinian and Arabian plant.
