varies quite as mucli as that species does. The diagnoses given above serve to dis- 

 tinguish them, especially the small size of the spikdets of A. oiliata, its annual baDU 

 and the large size of the tuhercles on which the far more copious rigid hnstw 

 are inserted. Roxburgh describes it as perennial and scandent, with stems mnny lees 

 long, rooting at the nodes, but Hackel has pointed ont that Roxburgh's^ descrip- 

 tion is that of an annual •, and as I have seen it growing in Bengal, it is raiue 

 a scrambler amongst bushes than scandcnt in a strict sense. The stems are a 



often erect with a geniculate base. „ \Fp^
