West Troricat Arrica. Angola, Gossweiler. 
The spikelets which are sessile on the short spike terminating 
the primary axis persist after the glomerules have fallen off. 
I have examined a number of these but have not found any grain 
although there is always an ovary present. I assume from this, 
thereforé, that they are usually, if not always, sterile.
