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 12- 

 14 cells across, the cortical band of cells in one or two layers of smaller cells; 

 stem paraphyllia absent. Bhizoids from the lamina of the branch uuderleaves 

 and the male bracteoles, the tips expanded to form deeply lobed discs. Line of 

 leaf insertion oblique, the leaves suecubous. 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 p., the 

 cuticle striolate-papillose ; lamina to six cells high, the cells averaging 62 X 13 p., 

 sometimes appearing connate with the uuderleaves 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 uuderleaves 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 subfioral innovations, the bracts and brac- 

 teoles 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 /' . Shoot/sporophyte relationship and sporophyte not seen. Fig. 3, a-e.
