Dioicous. Plants forming shallow, entangled tufts, at- 

 tached to the surface of moist earth, of a dull green colour. 

 Stems prostrate, linear, complanate, of moderate size, 

 sparingly branched (on a cross section, showing 8 cells in 

 diam., 20 to 25 cells in circumference). Leaves sub-opposite, 

 imbricate, plane or slightly convex, ovate- triangular, entire, 

 apex rounded, truncate, or rarely slightly retuse, antical 

 margin of leaf decurrent, at angle of 60° postical border 

 undulate 908 ; cells of a medium size, hexagonal, trigones 

 very minute. TJnderleaves connate with the adjacent leaves, 

 rarely with one only, about 1-5 smaller than the leaves, 

 decurved, subquadrate, from a cuneate base, quadrifid for 

 half its length, very rarely with an additional marginal tooth. 

 Perigynium on a short lateral branch proceeding from au 

 underleaf bearing one pair of bracts, with an additional 

 bracteole, which are connate for the lower half. Bracts 

 irregularly ovate, unequally dentate. Perianth cyathiform, 

 mouth wide, tri-laciniate, on section the perianth is composed 

 of one layer of 120 to 130 cells in circumference, slightly 

 winged near the apex, wing 6 cells wide ; mouth wide, with 

 3 or 4 segments, irregularly dentate. Capsule not seen, 



Androecium amentiform, proceeding from below an under- 

 leaf, small, with 3 or 4 pairs of leaves, antheridia single, oval.
