The plants of this species are highly variable in size and shape of the leaves 

 and underleaves and there is often considerable difference between the leaves and 

 underleaves of the stem and its branches or between those of different stems. 

 The length of the uniseriate tips of the leaves is less on robust than on slender 

 stems, or on branches. There may be no marginal teeth on the dorsal lamina of 

 the stem leaves or several teeth, none on the stem leaves and several on the 

 branch leaves or just suggestions of teeth along the margin. There are very 

 often one or two teeth along the ventral margin. A slender tooth on either side of 

 the lamina is characteristic in the underleaves, but there may be several teeth 

 or none. On some of the more robust plants the teeth are quite long. The cells of 

 the uniseriate tips of the segments are mostly 22-27 p. in length, but some are 

 only 18 fi.

Plants large, pale greenish-yellow becoming brown, in mats or mixed with 

 other bryophytes; stems to 6 cm or more long, with leaves 1.2 mm wide, prostrate 

 to ascending, regularly pinnate or bipinnate, the lateral branches frequent, densely 

 leafy, to 1.6 cm long, often becoming attenuate flagelliform at the tip, ventral 

 flagelliform branches scarce. Rhizoids with expanded tips, from the scales of 

 flagelliform branches. Line of leaf insertion oblique. Stem leaves closely imbri- 

 cate, squarrose, concave, 0.8-1.2 mm long, 1.1 mm wide at the base, the dorsal 

 lamina semicordate, the margins essentially entire, divided to one-fourth their 

 length into four or five segments; segments long, unequal, triangular, often 

 flexuose, ending in a uniseriate row of four to nine cells 30-36 p. long, from a 

 base three to eleven cells wide, the two segments on the ventral side of the leaf 

 often bent parallel to the stem; leaf cells of the base of the segments averaging 

 18 p, the lumina rounded, the walls thickened, the cuticle verruculose. Under- 

 leaves large, broader than the stem, longer than broad, to 0.4 mm wide, divided 

 to one-half or two-thirds their length into four or five long, slender, uniseriate 

 segments six to nine cells long from a 2- to 4-celled base, the cells 30-36 p. long. 

 Female bracts and bracteoles in three or four series, the innermost series broadly 

 ovate, divided to one-fourth their length into four or five laciniae. Perianth long, 

 contracted above, the mouth ciliate. Male inflorescence and sporophyte not seen.
