Epiphytic, rupestral or terrestrial ferns. Rhizomes long-creeping, terete or slightly dorsiventrally flattened, either lacking cavities or with hollow spaces inside or below often associated with ants, lacking sclerenchyma strands, pruinose or not, scaly or without scales or nearly so and spiny, sometimes also glandular hairy. Rhizome scales peltate, clathrate and occasionally marginally hyaline, orbicular to narrowly ovate, squarrose or appressed. Fronds monomorphic or occasionally dimorphic, articulated on short phyllopodia along the rhizome. Laminae undivided, variously lobed, or deeply 1-pinnatifid, herbaceous to coriaceous, glabrous. Veins reticulate, in type 5a or 5b pattern ( Nooteboom 1997), forming one to several series of areoles between costa and lamina margin, lacking main lateral veins that extend in a more or less continuous and straight line from costa to near the margin; largest areoles adjacent to costa, with free included veinlets, ending in hydathodes. Sori round or slightly elongate, or rarely the sporangia acrostichoid; superficial, or immersed in the lamina and often bulging on the upper surface; arranged in one row at either side of the costa, or deeply immersed in marginal semi-circular projections; paraphyses present or rarely absent; exindusiate. Spores monolete, bilaterally symmetrical, finely rugulate to tuberculate, sometimes with twisted strands around the spore.

Distribution — 24 species, one with two subspecies, occurring mainly in Malesia and Australasia, but extending to Thailand, Cambodia, Vietnam, and some western Pacific Islands as eastward as Fiji.
