Plants small, with the habit of Cephalozia dicaricata, reddish- 

 or brownish-green, densely and intricately csespitose. Stems very 

 rigid, comparatively thick, fragile, at the base leafless, slightly 

 radiculose, repeatedly ramose, most branches lateral or axillary, 

 below leafless, above leafy, eradiculose, a few (chiefly the lower 

 ones) postical, ieatless, flagelliferous and radiculose. Leaves sub- 

 transverse, lower ones distant, minute, appressed, upper gradually 

 laro-er and closer, ovato-quadrate, complicate, to the middle or 

 more acutely bifid, with acute segments; cells minute, sub- 

 quadrate, walls thickened. Stipules absent. Inflorescence dio- 

 icous. Female flowers terminal on repeatedly innovant proliferous 

 lateral (very rarely postical) branches. Bracts distichous, 2-3 pairs, 

 innermost 3 to 4 times larger than the leaves, ovato-quadrate, 

 from J to ^ bifid, lobes obtuse, rotundate. Perianth free, uni- 

 stratose, relatively large, semiemersed, oblong, Irontally com- 

 pressed, antical deeply unisulcate, postical bisulcate, with a smaller 

 obtuse keel between the furrows, apex broadly rotundate, mouth 

 small, minutely denticulate or setulose. Androecia situated at
