COLONEL MONRO'S MONOGRAPH OF THE RAMBUSACE^i:. 91 



"Flowers usually imperfect; I can sec no ripe seeds forming." In all tlic other spe- 

 cimens which I have seen from Buitenzorg and Kew (where the plants flowered in 

 Octohcr 1SG2), the G stamina are quite perfect, and the spicula is regular in all respects. 

 Lt is very closely allied to B. tuldu. I have observed in the living plants that the terminal 

 leaf of the branch is not as glaucous as the remainder of the leaves on the same branch.

This species, unless the following, P. nutans, should prove to lie a mountain form of it, 

 appears to be principally confined to the plains of Bengal and the nearly adjoining pro- 

 vinces ; but I am unable to distinguish specifically the specimens collected by Wallich 

 in 1827 in the teak-forests of Martaban, and contained in his herbarium No. 5027. The 

 section, however, of the stem which is attached to these specimens is much more solid
