on adaxial surface, with round to ovate scales with apiculate or caudate apices, center obscure brown, margins pale brown, fimbriate to ciliate; midribs and secondary veins not visible; sori oblong, with orbicular, peltate scales similar to those in the lamina; spores bilateral, abortive, prominently verrucate.

above, densely pubescent beneath.
Shrubs 1-5 m tall, stems green, glabrous or glabrescent
when young, pale gray and glabrous and minutely lenticellate at maturity.
7-5 cm, inconspicuously and sparsely white-lepidote near the apex to glabrescent
