rugosely reticulated, basal auricle sometimes incurved and overlapping the petiole, at 
others absent, nerves impressed above ; petiole -3 in., slender. Female spike young, 
Jin. long; peduncle as long hoary.—An obscure but very distinct plant, of which 
the specimens are insufficient. Miquel unites with it Wallich’s 6651 A (P. Chuvya, 
Hunter ?), which is a Siam plant collected by Finlayson and is quite different, having 
glabrous leaves; it is in too imperfect a state for determination. Cas. De Candolle 
quotes Chavica Arnottiana, Miguel, and Wall. Cat. 6651 A, B, under his P. Arnot- 
tianum, but describes from Wall. Cat. 6650 E, F, wbich are unquestionably P. Chaba. 
I do not know where Phuranbari, Hamilton’s habitat, is.

ing spike globose very shortly peduncled. P. vasculosum, Wall. Cat. 6660.

A much-branched twiggy shrub, 5-6 ft. high; branches terete, woody. Leaves 
membranous, rarely coriaceous, 3-7 by 1-31 in. nerves strong beneath, nervules 
transverse ; petiole slender, 1—3 in.; young leaves in Kumaon specimens are rounded- 
cordate. Male spikes only seen on Nilghiri specimens, 2-3 in., slender, drooping ; 
bracts minute, peltate; stamens 2; anthers reniform, cells confluent, dehiscing across 
the tip. Female spikes 4-} in. diam., rachis pubescent. Fruit 4, in. diam. ; stigmas 3, 
very minute.—Only to be distinguished from P. peepuloides by thé globose fruiting 
spikes, having like it the frequently warted branches. Amongst a host of speci- 
mens I have not one collected as male in the Himalaya, and suspect that the males are 
mixed up with those of P: peepuloides, khasianum and nepalense, which are often 
undistinguishable in young foliage. " i
