Species Description - Plants large, in pale yellowish-green tufts; stems coarse, 5-8 cm long, with leaves to 3 mm wide, irregularly pinnate to bipinnate, the branches to 1 cm long; stems in transverse section to 15 cells across, the cortical band of one or two layers of smaller cells; stem paraphyllia scattered and in clusters, five to eight cells long, rarely branched, uniseriate. Line of leaf insertion oblique, the leaves succubous. Leaves distant to approximate, spreading, more or less symmetric, to 1.5 mm long, 2.8 mm wide, divided to one-half of their length into six to eight unequal, branched segments; segments with the divisions opposite or whorled, densely ciliate, the cilia simple or branched, the cells averaging 83 X 12 µ, the cuticle striolate-papillose; lamina to seven cells high, the cells averaging 80 X 36 µ. Underleaves smaller, symmetric, to 1.0 mm long, 1 mm wide, deeply bifid, the halves again divided, the four to six segments and cilia as in the leaves. Branch leaves and underleaves similar but smaller and with fewer segments than those of the stem. Male and female inflorescenses and sporophyte not seen. Pig. 4, a-d.
