328 CLXXIII. GRAMINE2E. (J. D. Hooker.) \Myriostacltya. 



patent, flowering to the base. Spikelets i~s in., 4-8-fld., compressed, quite smooth ; 

 pedicels short ; gls. I and II unequal, keels scaberulous, awn ^ in. or more stifl 

 stout. In many respects Myriostachya is allied to Eragrostis cynosuroides, having 

 a very similar inflorescence, and spikelets jointed on the branchlets of the panicle ; 

 but differs in the spikelets being pedicelled, in the long awned gls. I and II, and in 

 its great size. 



Var. longispicula ; spikelets longer, up to \ in. and 8-20-fld. Penang, Curtis. 

 Ceylon ; at Kottiyar, Trimen. 



106. HALOPYRUM, Stapf. 



A tall stout perennial glabrous grass, with a branching creeping sheathed 

 rootstock. Leaves narrow, rigid, cou volute. Spikelets large, many-fld., 

 sessile or shortly pedicelled on the short alternate branches of an elongate 

 panicle, ovate, strongly laterally compressed, not jointed on their pedicels, 

 nor are the pedicels on the branches ; rachilla jointed at the base and between 

 the fig. glumes, silkily hairy. Glumes many, closely distichously imbricate, 

 dorsally rounded, coriaceous, keeled, I and II subequal, empty, ovate-' 

 lanceolate, acuminate or apiculate ; I 3-nerved, II 5-nerved; flg. gls. 6-lU, 

 rather shorter than the empty, mucronulate, 3-nerved ; palea as long as 

 the gl., subacute, 2-keeled. Lodicules 2, obcordate. Stamens 3. Styles 

 short, free, stigmas elongate. Grain ellipsoid, compressed, deeply hollowed 

 anticously, free.

Stem below creeping, as thick as a crow-quill, hard, smooth, woody, with strict 

 vermiform roots, sending up rigid slender flowering stems 12-18 in. high, and shorter 

 leafing ones. Leaves 8-12 in., flat or convolute, very narrow, wiry, glaucous, finely 

 acumin,ate, glabrous, sheath terete, appressed, striate, hard, mouth villous ; ligule a 

 few hairs. Panicle 12-16 in., erect or inclined ; branches short with few spikelets 

 and rachis quite smooth. Spikelets \ in. long, sessile or shortly pedicelled, 

 smooth, white or pale yellowish ; rachilla very short, hairs half as long as the gls. ; 

 gl. I hardly longer than the lowest flg. gl., ovate-lanceolate, apiculate, 5-nerved towards 

 the centre ; II longer, strongly 5-nerved. There being no specimen of Uniola 

 mucronata in Linnseus's Herbarium its citation here is doubtful.

108. DIPLACHNE, Beauv. 



Tall perennial grasses. Leaves flat or convolute, narrow. Spikelets 

 many-fld., spicate on the slender simple branches of a tall simple panicle,

 up.
