 and leaf-nerves beneath. Mishnri Hills in tipper Assam, Griffith.

 cular, peltate. Fruit very small, in dense cylindric rarely globose spikes, 

 sessile.

 pubescent in P. sylvaticum.

Stems creeping below ; " young shoots downy, branches prostrate or creeping with 

 broad leaves, flowering shoots erect/' Roxb. Lower leaves 2-3 in., often rounded- 

 ovate, acuminate, 7-nerved, sinus rounded but narrow, basal lobes equal ; petiole 

 1-3 in. ; upper leaves much narrower, with often unequal basal lobes. Male spikes 

 1-3 in. ; female -| in. Fruit about T 'g in. diam. The Malabar plant referred to 

 P. sarmentosum by Miquel (Lond. Jouru. Bot. 1. c.), and a Malacca one so named by 

 him, seem to me undistinguishable from P. longum, and I doubt sarmentosum being 

 a distinct species. Of the Mergui P. sarmentosum (Fl. Ind. Bat.) I have seen no 

 specimens. Wallich's P. sarmentosum (No. 6641) has broader upper leaves, and is 

 perhaps the true plant. He is the authority for referring Hunter's P. latifolium 

 to it.

A slender bush, climbing below with free spreading slender branches. Leaves 

 2-5 by 1-2 fu., variable in breadth, sometimes narrowed to a minutely cordate base ; 

 petiole of upper leaves ^-^ in., of lower rarely ^ in. Male spikes slender, 2-3 in., 

 x?lothed with peltate bracts; stamens 2-4 ; female 3 in., cylindric, longer than their 

 peduncle. Fruit T '. 2 in. diam. The branches are frequently warted as in P. brachy- 

 stachyum, to which this is most closely allied.
