Very like L. argentea, but can usually be distinguished by the more purple

 separated by the shorter squamella? and style.

 fuscous squarrose, glumes acuminate tip excurrent recurved, style 3-fid,

Plants varying much in size and habit. Leaves long, narrow. Spike- 

 lets in 1 or more heads, or panicled, often clustered. Glumes often 7-8, 

 lower more or less distichous, upper spirally imbricated; three lowest 

 (sometimes more) empty, fourth usually longer containing a perfect nut- 

 bearing flower ; uppermost more or less tabescent, male or sterile, thinner 

 in texture rounder on back than nut-bearing glume; above the fourth 

 glume another (in R. Sikkimensis 2-4 more) similar nut-bearing glume 

 follows. Hypogynous bristles often present. Stamens 3 (or 2-1), anterior. 

 Style long, linear, glabrous, branches 2, long or short, style-base dilated. 

 Nut oblong or ovoid, compressed, beaked by the persistent style-base 

 (clearly distinguishable from nut).-^-Species 150, in the warmer regioDS of
