Monoicous, acrocarpous or cladocarpous, densely csespitose, 

 eflagelliferous, small, pale green or subolive to reddish-brown. 

 Stems creeping or suberect, simple or slightly branched, flexuose, 

 firm, sometimes thick and fleshy, cortical cells 15-25, similar to 

 the inner, sometimes brown, sometimes hyaline 8-10 in diameter ; 

 radiculose, rootlets few, pellucid. Leaves distant or approximate, 

 near the apex of fertile branches crowded, broader than the stem, 

 patent-divergent, below concave-complicate or spreading, above 

 widely spreading or almost squarrose, oval-quadrate, bifid to 

 nearly the middle, sinus acute or obtusate, segments 5, 6 cells 

 wide at the base, acute or obtusate, divergent or erect ; cells small, 

 4-, 5- and 6-angled, subquadrate, walls firm, no trigones. Stipules 

 distinct on some stems, lanceolate-acute, sometimes above (sub- 

 bracteoles ?), bifid, sometimes minute or wanting. Flowers $ on 

 apex of main stem or on long or short branches. Bracts much 

 larger than the stem leaves, ovate-quadrate, bifid to about ^, sinus 

 broad, acute or obtusate, segments narrowly triangular, acute, 

 dentate ; bracteole smaller than the bracts, oval or ovate, bifid to 

 about ^, or ovate-lanceolate and entire, margin dentate or denticu- 

 late ; sub-bracts somewhat similar to the leaves but larixer, den- 

 ticulate or quite entire ; sub-bracteole bidentate or entire, margin 

 denticulate or quite entire. Perianth projecting much beyond the
