Zoll. & Moritzi by its smaller inflores- cence, larger more globose ovaries, more conspicuously flat-topped interpistillar staminodes, smaller appen- dix, its erect fruiting peduncle, tough primary veins, the leaves have less cordate base, numerous and closely spaced ( Hay and Yuzammi 2000).

Distribution and ecology. Widespread. Facultatively rheophytic on rocks in streams and on forest floor. ca. 300–1500 m elev.
