Plants small, epiphytic, seldom petrophytic. Rhizomes dorsiventral, with stipes in 2 rows; scales not clathrate, brown or reddish brown, glabrous. Stipe articulate or not, phyllopodia present or not. Lamina usually entire, rarely slightly crenulate; veins simple or 1- or 2-forked, free, vein endings sometimes with a hydathode on adaxial surface of lamina. Sori usually superficial or slightly sunken in shallow depressions on lamina, sometimes deeply sunken, on acroscopic vein branch unless veins simple, in 2 rows, 1 on each side of midrib. First-developed sporangia usually with 1-4 simple hairs at apex adjacent to annulus, rarely glabrous; later-developed sporangia glabrous. Hairs usually simple eglandular, either solitary or tufted, and rarely 1- or 2-forked with eglandular branches. Plants small, epiphytic, seldom petrophytic.
