    Species Description - Plants of medium to large size, light greenish-brown to dark brown, in tufts or pendent; leafy stems to 20 cm long, with leaves to 2 mm wide (when dry), sparingly irregularly branched, the branches both lateral, of the Frullania type and leafy, and intercalary, leafy or flagelliform; stem in transverse section or two or three layers of small, thick-walled cells surrounding the larger cells of the medulla. Rhizoids from the scale-leaves of the flagelliform branches. Leaves spreading, the bases imbricate, more or less asymmetric, 3-4 mm long, 1-1.5 mm wide, bifid to one-half of their length; segments long, lanceolate, curved, tapering to the acute apex, the margins entire, the vitta half the width of the base of the segment, ending below the tip; lamina ovate, with marginal appendages bearing slime papillae near the base, the vitta bifurcate a little below the sinus; leaf-cells thick-walled from coalesced trigones and intermediate thickenings, the walls uneven, the cuticle verrueulose. Underleaves as large as the leaves, similar, symmetric, the segments straight or divergent. Plants dioicous. Male inflorescence terminal, becoming intercalary on the stem, the bracts and bracteoles like the underleaves, the lamina pouched; antheridia large, spherical, in pairs in the axils of both bracts and bracteoles. Female inflorescence terminal on the stem, with one subfloral innovation—soon appearing to be on a short branch, the bracts and bracteoles in four to six series, increasing in size and elaboration to the innermost series, the bracts of the innermost series serrate, dentate, and ciliate on the margins. Perianth 3-parted to the middle, the divisions bilobed, the margins serrate, dentate, and ciliate. Sporophvte not seen. Fig. 1, a-p.
