Dioicous, laxly csespitose, flagella none or very rare, medium 

 to largish in size, pale green to pale dull brown in colour. Stems 

 simple or with one or two short postical branches ; slender, 

 delicate; cortical cells large, about 10, inner A, 5 diam, smaller; 

 radiculose, rootlets few, white, delicate. Leaves distant or approxi- 

 mate, alternate, spreading, horizontal or patent-divergent, oval or 

 oblong-oval, bilobed to below the middle, segments connivent or 

 spreading, large, unequal, lanceolate, acuminate ; texture lax, cells 

 medium to rather large in size, quadrate or oblong-quadrate, walls 

 delicate, no thickened angles or trigones. Stipules present on the 

 male plant only, shorter than the leaves, subulate or ovate-lanceo- 

 late, mostly entire, rarely bidentate at the apex. Fertile branches 

 elongate ; bracts oblong-ovate-acute, bilobed to below the middle, 

 segments lanceolate-subulate ; entire or with a small tooth below 

 the middle on one side ; bracteole broadly ovate, coarsely unidentate 

 on both sides ; sub-bracts ovate-lanceolate, only slightly bitid, 

 segments acuminate ; 3rd sub-bract small, ovate, bilobed to about 

 the middle. Perianth much exserted, large, linear-cylindrical, 

 obtusely trigonous, composed of a single layer of cells down to the 

 very base, about 70 cells round near the middle, mouth constricted, 

 denticulate, teeth 1 or 2 cells long. Calyptra oval, delicate. 

 Capsule reddish-brown. Spores reddish-brown ; elaters same 

 colour, bispiral, hardly as broad as the spores. Andrcecia on 

 short or long postical branches; perigonial bracts closely imbri- 

 cate, assurgent, broadly ovate, swollen at the base, bilobed to
