Common in all warm countries throughout the world; the 
most widespread and one of the most abundant of Cyperacee. 
The range of forms here supposed to be included under F. di- 
phylla is rather narrower than that ineluded by Kunth or by 
Boeckeler, who gave the species a new name (communis, Kunth, 
or polymorpha, Boeck.) to indieate that their species had wider 
limits than F. diphylla, Vahl. In the narrower sense here 
understood, the species has 140 names besides those above cited. 
The variation in development and in hairiness is very great. 
The stems and leaves are sometimes stout and rigid, the umbel 
with 50-100 spikelets, sometimes almost capillary with only one 
spikelet or very few (=var. lepfophylla, Benth. Fl. Hongk. 
p.392). Tne colour of the spikelets is usually a ferruginous 
brown, sometimes nearly black. The common form is glabrous 
or nearly so; but a hairy form (=var. tomentosa, Benth. Fl.
