Rhizoids frequent, long, in hyaline or yellowish-brown tufts from the lower part of the underleaf. Leaves subimbricate, widely spreading to ascendant, bordered, broadly to narrowly ovate, the apex broad, rounded, bidentate, the teeth erect to divergent, mostly uniseriate, 1 or 2 cells long, the sinus broad U-shaped, the dorsal base scarcely curved, the ventral base not decurrent; leaf border distinct, of rectangular cells below and subquadrate cells above; cells of the upper part of the leaf mostly hexagonal, 39-50 X 30-40 µ, the walls uniformly thickened, the cuticle essentially smooth. Underleaves bisbifid, distant, small, scarcely wider than the stem, the lamina usually 2 rows of cells high, the middle sinus lunulate, the segments short. Plants dioicous. Male inflorescence short, catkin-like, the bracts small, concave. Female inflorescence with 2 or 3 series of scale-like bracts and bracteoles. Perigynium 2-3 mm long, bearing numerous rhizoids.
