Species Description - Plants of medium size, julaceous, greenish-brown tinged with red, in tufts; leafy stems coarse, 5 cm or more long, with leaves to 2 mm wide (when dry), occasionally branched, the branches leafy. Line of leaf insertion transverse. Leaves erect-spreading, imbricate, symmetric, concave, broadly ovate, subquadrate, 2.5-3 mm long, 2 mm wide, bifid to one-third or one-half of their length; segments short, broadly triangular-acute to short-acuminate, the margins entire or with an occasional coarse tooth, the vitta one-eighth the width of the base of the segment, ending well below the apex; lamina broad, the margins strongly convex from a narrow base, entire, or with an occasional appendage near the base, the vitta bifurcate from the base. Underleaves like the leaves. Plants dioicous. Female inflorescence terminal on the stem, the bracts and bracteoles in four to six series, like the leaves but with more marginal teeth, the innermost series largest, the segments and margins incised with coarse teeth, the base with many cilia and appendages. Perianth (immature) 3-parted to one-half of its length, the divisions bilobed, the segments incised. Male inflorescence and sporophyte not seen. Fig. 9, a-f.
