this species and Pseudechinolaena polystachya Stapf (Echinolaena 
polystachya H.B. & K.), but in the former the back of the fruit 
is apparently adaxial and the lower glume is small and not 
herbaceous. The specimens quoted are scanty and in poor 
condition, but when better material is available it will show 
whether this affinity is true or only superficial, or whether the 
species is perhaps worthy of distinct generic rank. The nearest 
ally, Panicum numaeénse Bal. (in Bull. Soc. Bot. Fr. xix. 325, 
1872) from New Caledonia, may prove to be identical with it 
when more complete specimens of each species have been 
examined.
