Boott has called this “ C. ethiopica” and has noted that the spikes are all 
male at the base. In the true C. ethiopica of Schkuhr (the South Africa plant) 
the terminal spike is wholly male; and what is of more importance the lower spikes 
are not male at the base. In the C, ethiopica of Schkuhr, the female glumes are 
definitely bristle-tipped and longer than the utricle. 
Whether the present tropical plant be esteemed a species or only a variety of 
C. ethiopica, it is geographically sevarable,
