    Species Description - Plants of medium size, deep reddish-brown to blackish, tending to be radially symmetric, in erect tufts; stems slender, 7-8 cm high, with leaves to 2 mm wide, sparingly branched, the lateral branches long, leafy, of the Frullania type or rarely of the Microlepklozia type, or occasionally axillary-intercalary, the ventral branches rare, axillary-intercalary; stems in transverse section with a unistratose cortex of mostly smaller cells. Rhizoids infrequent, brown, from the bases of leaves and underleaves. Line of leaf insertion transverse. Leaves distant to imbricate, erect-spreading, bisbifid (some trifid) to two-thirds of their length; segments long, slender, tapering, widely divergent, lanceolate, mostly four cells broad at the base, the tip a row of three or more elongate cells, the end cell twice as long as broad; lamina cuneate, the area below each sinus thickened by a few bulging, variously oriented, superficial cells; leaf-cells at the base of the segment 30-50 X 24 µ, the walls thin, the cuticle faintly striolate. Underleaves like the leaves. Plants dioicous. Male inflorescence terminal, soon becoming intercalary on the stem, the bracts and bracteoles in three to seven series, the bracts deeply concave, the segments short, the bracteoles plane, similar to the underleaves; antheridia in the axils of the bracts. Female inflorescence terminal on the stem, without innovations, the bracts and bracteoles similar to the leaves and underleaves except for an occasional marginal tooth or a few basal cilia. Perianth inflated, with five broad keels, the mouth ciliate-dentate, contracted. Sporophvte not seen. Fig. 1, a-h.
