300 CLXXIII. GRAMINE^I. (J. D. Hooker.) \_Leptu chloa. 



Spreng. Syst. Veg. i. 288; spike solitary, spikelets 3-fld. Probably not a Lep- 

 tochloa. 



93. DICHJCTARIA, Steud. 



A tall slender perennial grass. Leaves long, narrow, flat. Spikelets 

 1-fld. with the very long filiform gl. of a 2nd, sessile or shortly pedicelled, 

 distantly scattered along a very long filiform rachis, very narrow, terete, 

 not jointed at the base; rachilla not produced beyond gl. Ill, -jointed at 

 the base. Glumes 4, I and II unequal, empty, separately deciduous, 

 narrowly lanceolate, acuminate or dorsally rounded, subaristate, entire 

 or minutely 2-toothed below the tip, 3-nerved; III linear, terete, coria- 

 ceous, 3-nerved, tapering into a very long rigid recurved awn with 

 two erect setae at its base ; IV, a filiform, awn-like, recurved glume, minutely 

 2-aristate above the middle; palea very narrow, 2-cuspidate, keels 

 scaberulous. Lodicules large, obliquely cuneiform, fleshy. Anthers 3, 

 very slender. Styles distinct, stigmas slender. Grain narrow.

SOUTHERN INDIA; Tranquebar, Bottler ; probably Travancore, Hero. Wight. 

 CEYLON, in dry parts of the island, Thivaites. 



Stems, erect, 2-3 ft., tufted on a creeping woody rootstock. Leaves as long as 

 the stem, A- in. broad, quite glabrous, margins smooth ; ligule of hairs. Panicle 

 12-18 in., rachis and few short tranches filiform, quite smooth. Spikelets with 

 the awns 1J in. long, green ; gl. I shorter than II, which is about ^ in. long and 

 about | as long as III below the short lateral bristles ; rachilla below III bearded. 

 I think Steudel was right in separating this grass from Gymnopogon, all the 

 species of which are American, and from which it differs totally in habit, and in 

 the form of the spikelets, gl. Ill of which greatly exceeds I and II. 



Tribe IX. FESTUCACE*:. (See p. 7.) 

 94. FOXKIKEREUXiXiA, Linn.f. 



A short stout perennial creeping grass. Leaves short, strap-shaped. 

 Spikelets 2-3-fld., distichously racemed, narrowly turbinate, villous, not 

 jointed on their pedicels ; rachilla stipitiform, narrowly obconic (resembling 

 a callus), villous, jointed at the acute base, crowned by empty deformed fl. 

 gls. Glumes 5-7, I and II narrow, persistent, empty ; I lanceolate, 1- 

 nerved ; II longer, oblong-lanceolate, 3-5-nerved; III and IV embracing 

 V and VI, empty, flabelliform, 4-lobed, dorsally shortly awned ; V-V1I flg. 

 cuneate-obovate, 3-lobed ; palea ovate, acute, nerves 2, pubescent. Lodicules 

 2, membranous. Stamens 2-3, anthers email. Styles distinct. Grain 

 oblong, compressed, free.
