This is a most interesting addition to the flora. As is well known, the 
genus Guadua differs but little from Bambusa, the chief character being 
in the broad wings to the keels of the palea. These are very well shown 
in Mr. Piper's specimen and in consequence I have described it under 
Guadua, a genus which hitherto has only been known as American. My 
only doubts are in the absence of lodicules and in the more Dendro calamus- 
like ovary. ^ Perhaps when ripe, or at any rate, more advanced, fruit 
is obtained it may be necessary to alter its position and genus and it is 
to be hoped that before long better specimens, including culm-sheaths, 
older spikelets, and the caryopsis may be obtainable.
