Stems stout, yellow-brown, often hoary, ascending to erect in deep cushions 

 or tufts or pendulous ; stems coarse, to 10 cm or more long, with leaves to 2 mm 

 wide, without paraphyllia, regularly pinnate ; lateral branches 5 mm or more 

 apart, long, spreading, often becoming attenuate-flagelliform and decurved in 

 the outer part. Rhizoids colorless, on the scales of the flagelliform branches. 

 Line of leaf insertion transverse. Stem leaves large, subrectangular, subsym- 

 metric, to 2.8 mm long, 0.9 mm wide, bisbifid ; segments long, lanceolate, without 

 cilia or laciniae, the margins crenulate, ending in a long, hyaline, uniseriate tip, 

 the end cell 140-180 p. long ; dorsal margin of the lamina convex, crenulate, with 

 to 12 hyaline cilia, two to ten cells long (in the South American plants), the 

 ventral margin crenulate; cells of the lamina tending to be in rows, those below 

 the segments 40-54 X 18-24 p., the trigones large, coalesced, the wall thick, wavy, 

 the cuticle striate ; a vitta of elongate cells extending from the base up into the 

 segments. Underleaves symmetric, scarcely smaller than the leaves. Branch 

 leaves and underleaves smaller. Plants dioicous. Male inflorescence intercalary 

 on a lateral branch, the bracts and bracteoles in two to sixteen or more series, 

 concave, similar to the branch leaves and underleaves, the margins with more 

 cilia, the bracts pouched, the bracteoles plane ; antheridia one or two, large, 

 with paraphyses, in the axils of the bracts. Female bracts and bracteoles larger 

 than the leaves and underleaves, with more cilia ; archegonia to 35 or more. 

 Coelocaule large, elongate, club-shaped, densely covered with paraphyllia and 

 scales, bearing unfertilized archegonia at the tip. Elaters long, 12-15 p wide, 

 bispiral between solid, long-tapering ends ; spores 33-37 p. coarsely spinose.
