A very distinct species originally described as Jatropha pungens, by Forskil, 
from specimens collected in Arabia, where it has again been met with by Deflers. 
In De. Prodromus, Miiller has separated the Arabian from the African plant ; 
while maintaining the former as a valid species, Miiller has referred the latter to 
f. mitis, Hochst. The Arabian and the African plants are, however, indistin- 
guishable; on the other hand, in addition to many morphological differences, 
f. cordifolia is easily distinguished from 7’. mitis in being moncecious not dicecious, 
and in being urticant not bland. The variety distinguished by Pax differs from the 
typical plant, much as 7’. brevipes, Pax, differs from 7. Benthami, Baker.
