Throughout warmer India, very common in rice-fields, from the Himalaya 

 to Ceylon and the Malay Peninsula. — Distbib. Trop. Africa, S.E. Asia, and 

 Australia. 



Usually hairy, sometimes (except inflorescence) glabrate. Stems 4-16 in. 

 Spikelets in clusters of 3-10, f by i in. ; bracts not much overtopping clusters. Sepals 

 linear, as long as nut or short, smooth or scabrous at top. Petals often as long as 

 nut ; lamina quadrate, cordate or hastate at base, 3-nerved, brown with 3 minute 

 teeth at top, glabrous or minutely hairy at top. Nut triquetrous ; beak cylindric, 

 sometimes minutely hispid. 



4. r. uncinata, Kunth Emutn. ii. 184 ; annual, clusters of spikelets 

 1-3 approximate (one distant sometimes added), glumes strongly hooked- 

 aristate, petals clawed broadly obovate pubescent on margin, nut ovoid 

 smooth brown. Boeck. in Linnxa, xxxvii. 108 {not Thw.). F. ciliaris,

Stems 4^8 in., hairy upwards. Sepals linear, shorter than nut, minutely retrorse- 

 Bcabrous or smooth. Petals nearly as long as nut, scarcely hastate at base. — Other- 

 wise as P. glomerata, to which it is closely allied, but readily distinguished by the 

 strong hooked bristles to the glumes. 



5. r. Trilobites, G. B. Glarke; annual, clusters of spikelets 1-3 

 approximate, petals very long-clawed with lunate heads long retro-cuspi- 

 date at base on each side, style 3-fid, nut ovoid smooth pale. 



Deccan Peninsula. Secunderabad j Wight ; neax B.^&t&h&i, Campbell. (The 

 same locality, and probably one collection.) 



Noted by Wight as perhaps a var. of SotthoelUi i.e. of F. glomerata, Lam. ; the 

 petals are different and remarkable. Spikelets rather slenderer (than in F. 

 glomerata), glumes blacker with longer green aristae. Petals as long as nut, their 

 head at top semicircular entire, their two lower angles long-produced downwards, 

 cuspidate. 



6. P. umbellata, Bottb. Bescr. et Ic. 70, 1. 19, fig. 3 ; rhizome creep- 

 ing woody, clusters of spikelets often many in an elongate panicle, petals 

 obovate subsessile, style 3-fid, nut ovoid smooth pale or finally brownish.
