Plants small, in whitish to light green or yellowish patches or among other 

 bryophytes. Stems 1-3 cm long, with leaves, to 0.5-0.8 mm broad, occasionally 

 branched, the branches ventral-intercalary, axillary, leafy or occasionally with a 

 male or female inflorescence; stem somewhat flattened, with 2 conspicuous rows 

 of dorsal cortical cells between the leaves. Rhizoids scarce, from small cells at the 

 bases of the underleaves. Line of leaf insertion sublongitudinal. Leaves plane, widely 

 spreading, tending to be trapezoidal in outline, the longer segment always triangular 

 and ending in a tip 2 cells wide, the 2 large elongate terminal papillae usually 

 present; cells of the upper part of the leaf mostly 39-52 X 26-35 the walls uni- 

 formly thickened, without trigones, the cuticle smooth. Underleaves mostly of 2 

 adjacent cells or, when bearing rhizoids, of many tiny cells. Plants monoicous. 

 Male inflorescence long, terminal or becoming intercalary on a branch, the bifid 

 bracts and the bracteoles in 7-12 series. Female inflorescence on a short ventral 

 branch with few leaves, the bracts and bracteoles larger than the leaves, deeply 

 bifid, the segments long-acute. Perianth long, cylindrical below, 3-keeled above, the 

 mouth long laciniate-ciliate.

Vegetative plant a small green thallus of the facies of Pallavicinia or Symphyo- 

 gyna, the axis or "midrib" flattened dorsally with 2 rows of large cortical cells 

 between the unistratose wings; wings broad, bearing very long slime papillae lying 

 parallel to the margin, occasionally the axis becoming wingless, flagelliform; axis 

 in transverse section of a cortical band of 8 cortical rows (2 dorsal, 2 with wings
