Plant small, rather stout, about 8-17 em. high. Rhi- 
zome creeping (usually fragmentary in our specimens). 
Roots numerous, fibrous, glabrous, slender, commonly 
unbranched. Stems short, stout, suberect to lightly flex- 
uous, approximate and spreading from the rhizome, 1- 
or 2-jointed, entirely concealed by two or three tubular 
imbricating sheaths or the fibres of sheaths, about 1-3 
em. long, 2-leaved at the apex. Leaves subopposite, 
widely spreading, oval to orbicular, sessile, apparently 
always rounded at the apex and sometimes with a small
