This species was identified by Mr. Clarke with the Indian 
plant he had previously described as S. supinus, var. uninodis, 
but it very conspicuously differs from that plant not only in 
stature, habit and general appearance, but also in structural 
details. And both this and the Indian plant distinctly differ 
from the Egyptian Isolepis uninodis, Delile, with which Mr. Clarke 
has supposed them to be identical; for besides the difference in 
locality and appearance, the Egyptian plant differs in having 
only two stigmas.

This is very similar in general appearance to the Abyssinian 
plant described above as S. confusus, N. E. Brown, but differs 
from that by the presence of long setae under the nut, the very 
short style and the smooth angles of the nut.
