 Rhizoids in tufts from the scale-leaves of flagelliform branches and the rhizome. 

 Leaves spreading to patent, imbricate, flattened, long-ovate, concave, acute, the 

 wing to five cells wide, extending from the apex to beyond the middle or to the 

 base, the margins crenulate, serrate, dentate and incised; leaf cells mostly 

 quadrate, 14—18 ft, a conspicuous mamillose projection over the ventral surface 

 of most cells, the walls thickened, trigones distinct, the cuticle finely to coarsely 

 verruculose. Underleaves large, broader than the stem, orbicular to truncate- 

 ovate, the upper margin undulate or 1- to 4-toothed. Plants dioicous, the male 

 and female inflorescences usually on short sexual branches from near the base of 

 the leafy stem. Male inflorescence basal, very rarely terminal on the stem, the 

 bracts in two to five or more pairs, small, concave, inflated, the bracteoles ovate; 

 anthcridia two, in the axil of a bract. Female bracts and bracteoles in several 

 series, the innermost series the longest, long laciniate-ciliate above. Perianth to 

 6 mm long, the mouth long ciliate-laciniate. Sporophyte not seen. PI. 61.
