57. CHLORIS, Sw. 



Annual or perennial grasses. Leaves flat or convolute. Spikes 

 solitary or several, iu terminal umbels or short racemes, erect or 

 ste'lately spreading. Spikelets of 2-4 florets (1 only or rarely more 

 fertile), sessile, crowded, unilateral, 2-seriate on a slender rhachis ; 

 rlvtchilia disarticulating above the invol. -glumes, more or less pro- 

 duced ; lowest floret hermaphrodite, the second male or barren (rarely 

 fertile), the following if present barren, often minute (some occasionally 

 fertile in G. tenella). Involucral glumes 2, persistent, narrow, keeled, 

 membranous, 1-nerved, acute, mucronate or the upper awned. Herma- 

 phrodite PLORBT : floral glume narrow or broad, 3-nerved, acute or 

 obtuse, minutely 2-toothed, usually awned from below the apex, often 

 ciliate ; palea almost equalling the glume, 2-keeled. Lodicules 2, 

 minute. Stamens 3. Ovary glabrous ; styles distinct, short ; stigmas 

 iterally exserted. Male tlobet : glume and palea as in the herma- 

 jhrodite flower but smaller and glabrous. Eudimentary florets 

 ■labrous, awned or awnless, small to miiuite, usuall}'^ without a trace 

 •f a palea. — Distrib. Species 40-45, in tropical and subtropical regions 

 )f both hemispheres. 



Annual ; spike solitary ; spikelets cuneate, 3-awned ; glumes 

 5-6; glume of hermaphrodite floret cuneale, the upper 

 margin naked 1. C. tenella. 



Perennial ; spikes 1-3 ; spikelets obconic, 4-awned ; glumes 5 ; 

 glume of hermaphrodite floret broadly ovate, with broad 

 hyaline margins, hirsute all over 2. C. villosa. 



Perennial ; spikes 4-6, in terminal whorls; spikelets narrowly 

 fusiform ; glumes 4, the upjierniost minute on the produced 

 rhachilla ; glume of hermaphrodite floret oblong-lanceolate . 3. C. i>ico)/iple(a. 



Perennial ; spikes 5-20 in a truncate fascicle ; spikelets 

 3-awned ; margins of glume of hermaphrodite floret densely 

 bearded above the middle, not hyaline 4. C. barhala. 



1. Chloris tenella, Roxh. Fl. hid. v. 1 (1832) p. 329. Annual, 

 very slender; stems 10-18 in. long, weak, slender, branched from the 

 base. Leaves 3-8 by \-\ in., flaccid, linear-lanceolate, finely acumi- 

 nate, the margins more or less ciliate towards the base ; sheaths 

 glabrous ; ligule large, membranous, truncate. Spike solitary, 1-2 in. 

 long, erect, flat. Spikelets large, reaching i in. long, cuneate, bifarious, 

 3-awned. Glumes 5 or 6 ; lower invol. -glume \ in. long, strongly 

 1-nerved ; upper invol. -glume longer and bi'oader, with a strong mid- 

 nerve which is produced into a short awn ; glume of hermaphrodite 

 floret \ in. long, broadly cuneate, the upper margin truncated, naked, 

 and with a scaberulous awn \ in. long from the back below the apex, 

 the palea elliptic with cihate margins, and the callus densely hairy, the 

 next or second floral glume smaller but similar, with a similar palea, 

 the others still smaller fan-shaped awned. Sometimes one or more 

 of the normally infertile glumes are found to be fertile, at other times 

 all are barren ; both forms may be found among the specimens in
