This is а pretty species which I cannot identify with any other I have seen, and 
which I consequently describe as new, but with some diffidence. I have received speci- 
mens from J. W. Oliver, collected from plants cultivated at Bernardmyo and called by 
the Shans ‘ Mai-pang-piik’ which I think belong also to this species. The culms are 
used for walking sticks,

Arborescent, or shrubby, or rarely climbing bamboos, sometimes thorny, sometimes of 
large size; a few species gregarious. Culms from a thick rhizome, usually ceespitose, occa- 
sionally stoloniferous from long underground shoots.  Culm-sheafhs various, the sheath 
usually broad and the imperfect blade broad, triangular in shape. Leaves small to moderate- 
sized, rarely large, linear or oblong-lanceolate, acuminate, shortly petiolate; Jeaf-sheaths 
variously auricled, Inflorescence more usually a large leafless compound panicle bearing 
spikelets in heads in spicate branchlets; sometimes in leafy panicles or paniculate spikes, 
and oceas onally short. Spikelets with 1 or many fertile flowers usually supported by
