 2: 728. 1943. 



Plants large, rigid, dull brown becoming blackish, ascending to erect, in deep 

 cushions or among other bryophytes; stems rigid, 6-10 cm long, with leaves to 

 1.0 mm or more wide, without paraphyllia, regularly pinnate (occasionally 

 bipinnate), the lateral branches frequent, often becoming attenuate- flagelliform 

 with decurved tips. Line of leaf insertion transverse. Stem leaves subsymmetric, 

 rectangular, to 1.6 mm long, 0.6 mm wide, usually bisbifid ; segments lanceolate, 

 sparingly laciniate, the tip attenuate, ending in a uniseriate row of four to eight 

 short, rectangular cells and a slime papilla, in part caducous; dorsal margin 

 of the lamina with occasional teeth and cilia, the ventral margin mostly entire, 

 crenulate ; leaf -cells tending to be in rows, those just below the segment 27-45 X 

 20-24 n, the walls thickened, trigones and pits frequent, an additional uneven 

 layer of thickening also present, forming an irregular band within the cell, the 

 cell lumina rounded, the cuticle verruculose to striolate; a well-marked vitta 

 extending from the base up into the segments. Underleaves symmetric, similar 

 to the leaves or scarcely smaller. Plants dioicous. Male inflorescence on a lateral 

 vegetative branch, the bracts and bracteoles in to 30 or more series, similar to 

 the branch leaves and underleaves, the bracts concave ; antheridia large, globose, 

 one or two in the axils of the bracts. Female inflorescence terminal on the stem 

 or a leading branch, the bracts and bracteoles similar to the leaves, larger; 

 archegonia 12 or more. Coelocaule large, club-shaped, covered with paraphyllia 

 and branched, lanceolate scales, the unfertilized archegonia at the tip. Mature 

 sporophyte, spores and elaters not seen. Pig. 3, a-d. 



Habitat : In wet places among mosses and over rocks and rock ledges.

Plants large, yellowish-brown, erect or ascending, in cushions. Stems coarse, 

 to 10 cm long, with leaves to 2 mm wide, with scattered filamentous paraphyllia, 

 pinnate ; lateral branches simple, widely spreading, decurved in the outer part, 

 usually becoming attenuate or flagelliform. Stem leaves asymmetric, ovate- 

 rectangular in outline, 1.9 mm long, 0.9 mm wide, bisbifid to the middle; seg- 

 ments undivided, with crenulate margins, the apex tapered to a uniseriate point 

 of four to eight cells, only one to three of the cells longer than the others ; dorsal 

 margin of the lamina strongly convex and bearing numerous cilia with long
