The four last collections are very similar: the more northern specimens 
rather constantly differ by having stouter petioles and rachises, and rigid leaves 
often pubescent on the under surface especially when young. Moreover, some 
of the spikes are leaf-bearing, until it becomes difficult to discriminate between 
them and leafy branches with axillary glomerules. Similar collections may have 
been the basis for the crediting to the Philippines, by Villar, of P. curgenteus 
(Forst.) Wedd. P. repandus has great external similarity to Oreocnide trinerms 
(Wedd.) Miq., but is easily distinguished by the inflorescence and flowers.

This is very definitely a woody vine; the Philippine plants identified as P. 
repandus have either this habit, or are at most low, greatly branching shrubs. 
The tendency of the leaves of Philippine P. repandus is to be wider than as 
described for that species, they measuring 5.7 to 10.5 cm long, 3 to 5.8 cm wide, 
and being nearly, uniform in shape are regularly about twice as long as wide. 
Those of P. succulentus, on the other hand, are from 6.5 to 12.5 cm long, 1.5 to 
3 cm wide, four times as long as wide: immature leaves showing the same 
proportions have been omitted in the measurements of both species; in both, 
also, much smaller leaves are present on the spikes. The nerves of the leaves of 
P. succulentus, on one or both sides, more often extend to the base of the acumen, 
in some eases even into it, less often they vanish before reaching it. The stipules 
are slightly longer than in P. repandus, about 5 mm, and are not so deeply cut, 
about half-way to the base, but the margin of difference is slight. The spikes 
are more often solitary, but sometimes fascicled.
