    Species Description - Plants of medium size, brown, in tufts or pendent; stems to 15 cm long, with leaves to 2 mm wide (when dry), rarely branched, the branches leafy. Line of leaf insertion transverse. Leaves tending to be falcate-secund or irregularly spreading when dry, 3-4 mm long, to 1.5 mm wide at the ovate base, bifid to about one-half of their length; segments spreading, lanceolate, tapering to a 2-3-celled tip, the margins entire, the vitta only half as wide as the segment base, ending well below the apex; leaf-cells thick-walled, the trigones and pits rarely distinct, the margins irregular, the cuticle verruculose; lamina ovate, the margins often incised, toothed, or ciliate at the base, the vitta forked near the base, continuing as two distinct ribs into the segments. Underleaves as large as the leaves, the lamina less ovate, the segments conspicuously divergent. Plants dioicous. Male inflorescence terminal but becoming intercalary on the stem, the bracts and bracteoles as large as the leaves and underleaves, pouched; antheridia large, spherical, in pairs in the axils of the bracts and bracteoles. Female inflorescence terminal on the stem, with one subfloral innovation, the bracts and bracteoles in four or five series, the innermost series largest, with a long lamina with decurved marginal teeth and cilia, the segments divergent, linear. Perianth (immature) 3-parted to near the middle, the divisions deeply bilobed, the segments narrow, linear. Sporophvte not seen. Fig. 3, a-e.
