Description
Species Description - Plants large, yellow-green to olive-green, prostrate, caespitose; stems large, 3-5 cm long, with leaves, 2-3.8 mm wide, sparingly irregularly branched; branches ventral, axillary-intercalary, leafy or rarely flagelliform or sexual. Rhizoids few, long hyaline, from small basal cells of the underleaves. Line of leaf insertion oblique, nearly longitudinal. Leaves widely spreading, bordered, subimbricate, asymmetric, long ovate, the dorsal margin often straight from a curved base, the ventral margin strongly arched above from a slightly decurrent base, the apical end broad, often truncate, mucronate; leaf border conspicuous, of 2-4 obliquely overlapping thick-walled cells 100-150 X 10—13 µ with tapering ends, extending from the base and forming the mucronate tip; cells of the upper part of the lamina 20-40 X 13-26 thin-walled, the trigones small or absent, the cuticle coarsely verruculose. Underleaves broader than the stem, broadly ovate to suborbicular, the apex rounded to blunt-pointed or shortly bifid, bordered by long cells as in the leaf, the lamina of shorter, thin-walled cells of similar texture. Plants dioicous. Male inflorescence on a short sexual branch, bud-like, single or rarely two or three in the axil of an underleaf, the male bracts and bracteoles in 4 or 5 series, the bracts small, bifid, concave. Antheridia one to three in the axil of a bract. Female inflorescence and sporophyte not seen.
