Plants yellowish brown, densely cespitose: stems ascending, 
long, robust, irregularly pinnately branched, branches sometimes 
attenuate, flagelliform ; flagella numerous, very long, slender, micro- 
phyllous: leaves imbricated at the base, apex free, subfalcate, spread- 
ing, narrowly obliquely ovate, antical base curved, arching over the 
stem, postical not decurrent, line of insertion curved slightly inward, 
apex obliquely truncate, tridentate, teeth broadly triangular, acute, 
sometimes apiculate, about 4 to 8 cells broad, 6 to 14 cells long and 
ending in a row of 2 to 5 cells, sinuses obtuse or lunate: underleaves 
approximate or distant, suborbicular, apex truncate, rounded or 
slightly retuse : leaf-cells at apex with uniformly thickened walls, in 
the middle oblong, thick-walled, with small trigones, at middle of base 
large, with substellate cavities and large trigones, cells at antical edge 
oblong, with long axis perpendicular to edge, thick-walled, trigones 
small: cells of underleaf similar to those of leaf: @ inflorescence 
borne on a very short branch ; Q bracts in about 5 pairs; innermost 
bracts broadly ovate, the upper portion denticulate, bifid to quad- 
rifid, lobes subulate, 2 to 4 cells broad, 6 to 10 cells long, ending in 
arow of 4 to 6 cells; cells of bract elongated with thickened walls; 
innermost bracteole similar to bracts; bracts and bracteole of second 
row similar to those of innermost row but smaller; perianth ovoid- 
cylindrical, terete below, many keeled above, mouth deeply lobed, 
lobes laciniate, laciniz about 4 cells broad, 6 to 20 cells long, denti- 
culate at the base, ending in a row of 2 to 4 cells; cells of perianth 
elongated, with numerous intermediate thickenings: capsule oval,
