gregariously and in small clumps. The following species of most authors are here 

 united. The two first scarcely differ, the last seems more nearly a separate 

 species and the remarkable rachis justifies its admission as a variety. — Further B. 

 arundinacea shows two distinct varieties of habit, a tall handsome large stemmed 

 one of the valleys of the Circars and hills of S. In(Ua (often cult, elsewhere) ; and nn 

 almost dwarf gregarious thick branched very thorny small-stemmed one 20 tt. high 

 (probably Roxburgh's B. spinosa) which grows gregariously in the low hills and 

 laterite downs of Orissa, Ganjam, Lower Bengal and Burma. 



B. AKUXDiNACEA; rachis of infl. very glabrous shining hard, spikelets few long 



6-12-fld., rachilla evident hirsute, leaves smooth, sheath hairy. a « AH 



B. SPINOSA, rachis striate hard not shining, spikelets many shorter 4-b.fla., 



rachilla obscure, leaves glabrous above hairy beneath, sheath hairy, then subglabrons. 

 B. ORiENTALis ; rachis glaucous green angled almost soft, spikelets membranous 



5-8-fid., leaf-sheath hairy with white cilia, petiole hairy.
