Barren specimens of what is probably the same species were 

 collected by Dr. Coppinger on Cerf Island, Providence Reef, 

 North of Madagascar. They exhibit the same mode of growth, 

 but the leaf-blades are much less rigid, narrowed towards the 

 base, always quite glabrous and up to 3'5 cm. by 5-7 mm. The 

 tufts are 5-7 cm. high. The affinity with B. ramosa is quite 

 clear and one might consider the species described here as an 

 extremely stunted condition of it if it were not for the smaller, 

 narrower, and very smooth spikelets and their mure reduced 

 lower floret.
