Heteroicous (monoicous and paroicous), depresso-csespitose, 

 medium to largish in size, pale to dark green in colour. Stems 

 prostrate or apices assurgent, moderately firm, simple or rarely 

 furcate, branches postical, elongate, attenuate, gemmiparous ; 

 radiculose, rootlets many, proceeding in tufts from base of the 

 stipules. Leaves usually small at the base and at apex, largest at 

 the middle of stem, imbricate, incubous, alternate, patent-divergent 

 or horizontal, slightly convex, ovate, entire, apex rotundate or 

 rarely acute, or very slightly bidentate, cells lax, oblong-hexagonal 

 or hexagonal, medium to rather large, walls thin, trigones very 

 small. Stipules nearly half the size of the leaves, about twice as 

 broad as the stem, subrotund, bifid to about a third, refuse or 

 subentire, lobes obtuse, sinus obtuse, margin entire. Bracts very 

 small, 2 or 3 pairs, oblong-quadrate, slightly bifid. Perianth 

 arising from axil of stipule, pendulous, subterraneum, cylindrical 

 or subclavate, carnose, composed of several layers of cells, near 

 base 6 layers, near the mouth surrounded by layers of small and 

 broadly subulate scales, which are often found on other parts of 

 the perianth; radiculose, rootlets long delicate hyaline, interior 

 layer covered with long papillae, composed of single, elongated 

 cells. Calyptra free, 2-4 cells thick near the base, pistillidia 

 long, narrow, about 10. Pedicel thick, about the same diameter 

 as the capsule. Capsule cylindrical, 3 to 4 times longer than 

 broad, composed of two layers, valves spiral, linear. Spores pale 

 brown. Elaters reddish-brown, 20-30 turns of the spiral, bispiral. 

 Androecia bud-like, sometimes catkin-like, postical, situated in the 

 axil of the stipule, near the $, perigonial bracts very small, 

 about 3 to 4 pairs, subrotund, trifid, segments acute, sinus obtuse, 

 antheridia about 10, oval. 



Gemmae often pedicellate, in spherical heads, yellow-green.

 diameter, with leaves 3* mm. broad; leaves 2* mm. x 1*5 mm., 

 sinus "1 mm. ; cells '04 mm. x "03 mm., "07 mm. x '04 mm.,
