lower ones usually loosely ramulose. Flowers dimorphic, 

 pedicellate ; pedicels 1-i-fasciculate, articulated, bracteolate at 

 the ba^e. 



Monotypic. The characteristic of the genus which is to 

 be distinguished from other allied genera, are those of the di- 

 stichous and articulated leaves and fibrillose seeds.

Perennial, glabrous. Rhizome very short, thickish, densely 

 rooting, with leaves, short fibres of old vaginas and a few scaly 

 leaves at the top ; roots numerous, radiato-fasciculate, slender or 

 carnoso-incrassate, often minutely tomentose, shortly branched. 

 Leaves radical, caespitose, distichous, several or subnumerous 

 (about 6—11), falcato-ensiform and all declinate to one side, 

 articulated with the short vagina at the base, long-attenuated 

 with an obtuse small point at the apex, entire with smooth

 broad ; midrib slender ; veins about 7-16 on each side, parallel ; 

 transverse venules very loose and inconspicuous ; scaly leaves 

 few, subulato-acuminate, attaining about 7cm. long. Scape 

 aphyllose, about 2|-7decim. long including the panicle, very 

 compressed, ancipital, often angustately alate on edges, attain- 

 ing about 6mm. in width. Panicle composed with racemes, 

 broadly and shortly pj^ramidal, vshorter or longer than the 

 scape (peduncle), nearly equal to or exceeding the leaves in

 long ; rachis straight or slighth' flexuous, angulato-compressed ; 

 primary bracts angustate, linear, attenuated towards the apex,
