Dioicous, of medium size-rather large, brown-brownish green, on bark or usually on soil. Stem to 3 cm long, 200-220 µ in diameter, usually dark brown, cortical cells about 20 x 40 µ. Leaves subopposite, plane-somewhat convex towards the dorsal face, entire or somewhat emarginate apically or sometimes undulate and with a few short teeth, apex rounded or somewhat emarginate, upper margin arched, lower margin slightly S-shaped, decurrent on the dorsal face of the stem and frequently also on the ventral. Marginal cells 24-30 x 30-45 µ, cells in the centre up to 40 x 50 µ, walls thin, trigons small-large. Scattered single or groups of hyaline, pale red or red-brown cells in the leaves. Oil bodies 5-12 per cell, composed of small, up to1 µ large drops, yellow-brownish gray, 4-8 µ in diameter or up to 5 x 10 µ. Amphigastria small-rather large, of varying shape, connate with the upper margin of one or both the adjoining leaves, with ± short, sometimes rather long acute lobes, lateral margin ± dentate, sinus obtuse-subcute, shallow. Female bracts larger than the leaves, oblong, apex emarginate-truncate, reflexed. Bracteole with apex truncate and small teeth on one of the lateral margins, the other margin connate with the adjoining bract. Perianth broadly ovate-cuneate, compressed and with mouth truncate-somewhat crenulate-dentate. Androecia apical, with up to 15 pairs of bracts, smaller than the leaves. Dorsal margin of the bracts reflexed, basal portion concave and contains one antheridium, the perifer, larger portion is convex and recurved towards the ventral side, lobule large, saccate, almost rectangular with a right angled apex in the free margin.
