2. Cephalozia subforficata Herzog, Rev. Bryol. Lichen. 11: 17. /. 1, g-h. 1938. 



Plants small, slender, pale green often tinged with brown, in mats or scattered 

 among other bryophytes; stems prostrate, 1-2 cm long, with leaves 0.4-0.6 mm 

 wide, irregularly branched; branches ventral-intercalary, leafy or rarely flagelliform, 

 or short and bearing a male or female inflorescence. Rhizoids frequent, from cells 

 of the ventral side of the stem, the tips branched. Line of leaf insertion nearly 

 longitudinal. Leaves distant to approximate, plane, widely spreading to slightly 

 ascendant, falcate, the dorsal margin strongly convex, 0.5 mm long, 0.15 mm wide, 

 often smaller with the cells in rows, in leaves near the tip of the stem, decurrent, 

 bilobed to one-third the length, the segments erect to slightly curved, not connivent, 

 long, triangular from a 2-celled base, the tip a row of 2 or 3 cells; cells of the tip 

 to twice as long as wide, 26-30 /x long, cells of the upper part of the leaf variable 

 45-52 n long and wide, with a few 26-35 fx, the walls thin, without trigones, the 

 cuticle smooth. Underleaves absent. Plants dioicous. Male inflorescence on a 

 ventral branch, spike-like, the bracts resembling the leaves, densely imbricate, 

 bilobed, concave. Female inflorescence on a short branch, the bracts and bracteoles 

 in 3 or 4 series, bifid, the segments of the inner series slender, long-acuminate, 

 ending in a row of 3 cells. Perianth long cylindrical below, 3-keeled above, the 

 mouth long-ciliate, the cilia 3 or 4 cells long, the cells mostly 130 X 20 p. Sporo- 

 phyte not seen.
