Rhizoids abundant, long, branched at the tips, in light brown tufts from small cells near the bases of underleaves. Leaf insertion slightly oblique, nearly longitudinal. Leaves imbricate, widely spreading to patent, more or less bordered by smaller cells, orbicular to rectangular, 0.95-1.7 mm long, 0.66 mm wide at the middle, the apex broad, truncate-rounded, the dorsal base slightly curved, the ventral base decurrent, the margin crenulate; leaf border of 1 or rarely 2 rows of somewhat smaller, bulging cells, 20-25 X 20-25 µ, the walls thickened; cells of the upper part of the leaf 30-40 X 30-40 µ, the walls thin, the trigones small, the cuticle punctate. Underleaves orbicular to reniform, wider than the stem, twice as broad as high, shortly bifid with broad rounded lobes, the cells mostly isodiametric, thin-walled, the margin regularly crenulate. Plants dioicous. Male inflorescence a short or long catkin-like branch, the bracts and bracteoles in 3-10 series, scale-like, concave.
