Stems prostrate, with rootlets very long, pale or reddish, 

 slightly (laterally) branched, rarely flagelliferous. Leaves ovate- 

 oblong, sublingulate, apex rotundate or retuse, very rarely sub-

 Stipules absent. Inflorescence dioicous or paroicous. Female 

 flowers terminal. Bracts $ 1-2 pairs, similar to the leaves only 

 broader. Pistillidia 5-12. Perianth at first pyriform, afterwards 

 cylindrical, incurved, eplicate, apex abruptly rotundato-constricted, 

 mouth minutely ciliolate. Capsule highly exserted, dividing 

 down to the base into 4 valves, composed of two layers, inner 

 layer with semi-annular fibres. Elaters attached to the middle of 

 the valves, bispiral. Spores globose, minute, as broad as the

Paroicous or monoicous, ^ flowers usually immediately below 

 the ? bracts, sometimes on proper branches which proceed from 

 below the perianth, densely ceespitose, small, pale or dark green 

 to a greenish-brown in colour. Stems dark brown, 30 cortical 

 cells, slightly darker than the inner ones, of equal size, about 12
