3 to 4 mm in diamete /up to 5 mm apart, stigmas Bot inch:Jed in these 
measurements: pistillate perianth about 1 mm long, more, or less pubes- 
cent, conforming to the shape of the ovary and adnate to it, the apex 
very shortly and obscureivv 4- or 5-lobed ; stigma 3 to 4 mm long, densely 
pubescent except at the extreme base, deciduous. "^ 
A woody vine, ^vide y branching, the branches terete )r toward the 
apex obscurely obtusely angled, the bark brown, glabre cent near the 
base, elsewhere densely covered with short white audofen^ginous pubes-

out system, the former 3 to 16 mm long, pubescent like tne branchcb, the 
lamina coriaceous, rigid, oval or narrowly oval, 4.2 to 12 cm long, 24 to 
67 mm wide, the base Varying from acute to subcordate, the margins 
entire or subentire, th.. apex merely rounded or shorts acuminate, 3- 
nerved, the nerves extending at least four-fifths of the length of the 
lamina, often almost to its apex, with numerous anastoi:^ - 'ng veins 
connecting the costa and the nerves, conspicuous on the under '^surface, 
but with only one or two primary veins and they near the apex, the 
reticulations slightly pubescent and brownish in color, forming a strong

Closely allied to P. argenteus (Forst.) Wedd., differing in' the habit," .he 
shape, apex, and somewhat in the pubescence of the leaves, and the fr ^ci<.led 
spikes. It is curious that three out of our pix species should be scahde. : 'iroas 
of the eight enumerated by Weddell only P. rotundifolius (Poir.) V\ . '. >om 
Mauritius, is so described; also, that w''ile we have two closely allied species 
with free stipules, the only other that api o.iches them should also be the uiosest 
to them in other characters.
