Plants large, in yellow- to olive-green mats; stems creeping, to 7 cm long, with 

 leaves, to 3 mm or more broad, irregularly pinnate; branches frequent, long, leafy, 

 ventral-intercalary from the axils of the underleaves, sometimes small-leaved, occa- 

 sionally branched; stem in transverse section of similar cells throughout. Rhizoids 

 occasional, hyaline or yellowish, in a tuft from the base of an underleaf. Line of 

 leaf insertion oblique, the dorsal end scarcely curved. Leaves imbricate, widely 

 spreading, tending to be slightly ascendant, subrectangular, 1.1 X 0.84 mm, the 

 dorsal base slightly curved, the apex broad, truncate-rounded, the ventral base 

 scarcely decurrent; cells of the margin of the upper part of the leaf variable, 

 30-52 X 20 p., often broader than high and forming an indistinct border; cells of 

 the upper part of the leaf 30-50 X 30 /x, hexagonal to elongate, the walls uniformly 

 thin, without trigones, the cuticle smooth. Underleaves longer than broad, a little 

 broader than the stem, bifid to below the middle, the segments narrowly ovate-acute, 

 the cells elongate. Female bracts and bracteoles in 3 or 4 series, the intermediate 

 series to 0.96 mm long, pale, the cells elongate. Male inflorescence and sporophyte 

 not seen.

Plants of medium to large size, pale yellowish to green becoming tinged with 

 brown, in mats or scattered among other bryophytes; stems prostrate, to 6 cm long, 

 with leaves 1.5-2 mm wide, irregularly pinnate; the branches often long, leafy, 

 ventral-intercalary from the axils of the underleaves; stem in transverse section of 

 a variable cortical layer, those cells under the leaf insertion very large. Rhizoids in 

 light yellow-brown tufts from the bases of underleaves. Line of leaf insertion 

 oblique, nearly longitudinal. Leaves approximate to subimbricate, inconspicuously
