Description : A perennial, tall, erect grass. Culm 0-9-1-6 m. high, soft. 

 Leaves linear-lanceolate, broadly cordate at base, 20-35 cm. by 24-30 mm. glabr- 

 ous or sparsely hairy beneath. Sheath glabrous or sparsely hairy Vvith villous 

 mouth. Ligule very short. Panicle long contracted or more or less effuse, 20-45 

 cm. long, fastigiately branched, branches erect, 5-12 cm. long, branchlets and 

 fascicles of spikelets subsecund. Spikelets green, glabrous, 1-7-2-5 mm., sessile 

 or shortly pedicelled, strongly nerved, subacute. Lower involucral glume 

 broadly ovate, i - \ the length of the lower floral, obtuse or acute, nerves 3-5 

 arching, upper involucral and lower floral subequal, ovate-oblong, acute or 

 acuminate, 5-nerved, pale of lower floral glume small, neuter. Upper floral 

 glume as long as the lower, lanceolate-acuminate, smooth, white, thinly 

 coriaceous. 



Locality : S. M. Country : Castle Rock (Gammie 15717 i). 



Distribution : India, Ceylon, Malay Peninsula, Malaya, China. 



53. Hymenachne, Beauv. Agrost. (1812), 48, t. 10, f. 8. 

 Rather stout grasses. Leaves broadly linear. Panicles thyrsoid, branches 

 erect, appressed with spiciform branchlets and very numerous crowded nar- 

 rowly lanceolate acuminate secund spikelets, articulate on their minute 

 pedicels. Lower involucral glume cuspidate, keeled, membranous, shortest, 

 upper with sheathing amplexicaul base on the long internode of the rhachilla 

 between it and the lower floral glume, prominently 3-nerved, cuspidate or awned. 

 Lower floral glume longest, lanceolate-acuminate, passing gradually into the 

 awn, with three strong nerves meeting in the base of the awn and two lateral 

 weaker ones, empty; upper longer than upper involucral glume, oblong, mem- 

 branous in flower scarcely hardened in fruit, smooth, faintly 2-nerved, embracir g 

 the pale except at the tip, pale similar and as long. Lodicules minute. Stamens 

 3. Styles free. 

 This genus is not represented in Cooke. The following species is described

Description : Culm stout, tall, 0-6-L8 m. high, spongy below, rooting at the 

 nodes of the prostrate base, erect, leafy. Leaves 20-50 cm. by 18-25 mm. flat, 

 tapering from a broad cordate base to a fine point, margin serrulate ; sheath 

 smooth, glabrous or ciliate ; ligule very short, rounded, hyaline. Panicle very 

 dense, narrow, very compound with closely appressed branches, 15-30 cm. 

 long, rarely 25 mm. diam., often interrupted, sometimes quite cylindric. Spike- 

 lets variously grouped, shortly and unequally pedicelled, secund on the erect 

 branches of the panicle, 4-6 mm. long, narrowly lanceolate, pale green. Lower 

 involucral glume i of the lower floral glume, narrow from an amplexicaul base, 

 aristulate, hispidulous on keel and cusp ; upper narrowly lanceolate, subaris- 

 tate, hispidulous, 3-nerved. Lower floral glume much longer than upper 

 involucral glume, narrowly lanceolate, gradually tapering into the awn as long 

 as spikelet, strongly 3-nerved, hispidulous on nerves, pale imperfect or ; 

 upper small, thin, narrow, finely acuminate, almost embraced by the lower, 

 shorter than the upper involucral glume, enclosing its pale on the edges. 

 Styles distinct. 



Locality: S. M. Country: Tadas, tanks, elevation 2,000 ft., rainfall 35 

 inches (Sedgwick .& Bell 4917 !).
