    Species Description - Plants large, in pale yellowish-green tufts; stems 6-7 cm long, with leaves 2 mm broad, pinnate, the branches 4-5 mm long; stems in transverse section 1214 cells across, the cortical band of cells in one or two layers of smaller cells; stem paraphyllia absent. Rhizoids from the lamina of the branch underleaves and the male bracteoles, the tips expanded to form deeply lobed discs. Line of leaf insertion oblique, the leaves succubous. Leaves spreading, closely imbricate, asymmetric, to 1.3 mm long, 2 mm wide, divided to one-half of their length into five or six unequal, often branched segments; segments narrowly triangular, densely ciliate, the cilia simple or branched, the cells averaging 96 X 20 µ, the cuticle striolate-papillose; lamina to six cells high, the cells averaging 62 X 13 µ, sometimes appearing connate with the underleaves at the base. Underleaves half as wide as the leaves, symmetric, to 1 mm long, 1 mm wide, quadrifid (bisbifid), ciliate as in the leaves. Branch leaves and underleaves similar to but smaller than those of the stem. Plants dioicous. Male inflorescence intercalary on a lateral branch, the bracts and bracteoles in eight or more series, the bracts concave, to 1.2 mm long, 2 mm wide, divided to one-third of their length into five or six short, ciliate segments; antheridia large, globose, in pairs in the axils of the bracts, the stalk eight to ten cells long. Female inflorescence terminal on the stem or branch, with one or two subfloral innovations, the bracts and bracteoles in three series, the innermost series largest, the bracts to 2 mm long and wide, divided to one-half of their length into eight or ten unequal, often branched segments, ciliate as in the leaf, the cells of the lamina averaging 84 X 25 p. Shoot/sporophyte relationship and sporophyte not seen. Fig. 3, a-e.
