The specimens from Loanda resemble those from Madagascar, 

 having rather tall elongated shoots, with a large dift'use panicle. 

 Those from Mossamedes are, as we might expect from their 

 psammophilous habit, low-growing, with a number of shorter 

 decumbent shoots spreading from the rooting nodes of the 

 rhizome ; the panicle is also much smaller and very dense. 



Var. brevispiculum Rendle var. nov. 



Distinguished by its smaller and more delicate inflorescence, 

 smaller spikelets, and invariably truncate barren glumes.
