272 NOTES ON THE FLORA OF CEYLON. 



and the locality given for this is "Ceylon." Under these circum- 

 stances I believe our plant to require a name, and I now leave it 

 under Thwaites' very appropriate appellation, though in the list of 

 additional C. P. numbers at the commencement of this paper I have 

 given it as P. cashmi Nees. 



Panicum. blephariphyllum Trim. — Leaf-sheaths smooth or 

 the upper ones with scattered spreading bristly hairs ; ligule 

 obsolete ; blade broadly linear, gradually tapering to apex, broad 

 semi-amplexicaul and auricled at the base, closely veined, thin, flat, 

 glabrous on both sides, the margin furnished with long, fine, 

 straight, spreading, stiff cilia from small bulbous bases ; panicle 

 long-stalked, 8-10 in. long; branches solitary or two together, 

 scattered, ascending, rough, slightly branched, with a tuft of long 

 hairs at base ; spikelets stalked, solitary, about |- in. long ; lowest 

 glume more than three-fourths the length of the spikelet, strongly 

 apiculate, broad, normally 3-nerved, the nerves strongly scabrous ; 

 2nd glume acuminate-cuspidate, with central midrib and a pair of 

 closely-placed nerves on either side, smooth ; 3rd glume rather 

 shorter, acute, similarly veined, with a male flower in axil ; 

 flowering-glume about half the length of 3rd, obtuse, thick.

Very near P. Leptochloa Nees (C. P. 918), especially in the 

 spikelets, which scarcely differ save in being rather longer and less 

 crowded, and with somewhat broader glumes. Both belong to that 

 group of Panicum in which the lowest glume approaches the others 

 in length. P. Leptochloa is, however, a more slender grass ; and 

 its leaves are narrow and rigid, and not or but very slightly dilated 

 at the base ; nor have they the marked ciliation of the margin. 



I notice that the lowest glume is very frequently 4-nerved, and 

 then somewhat unsymmetrical. 



Dimeria laxiuscula Thw. ms. — Perennial, tufted ; stems 

 erect, rather slender, 2-3 ft. high, scarcely branched ; nodes with a 

 thick tuft of white silky hair ; leaf- sheaths smooth in lower, hairy 

 in upper part ; blade narrow, linear, erect, strongly keeled, more or 

 less hairy on both sides, and long-ciliate on margin ; ligule short, 

 truncate ; spikes 5-10, 3-4 in. long, slender ; spikelets small, 

 shortly stalked, each with a short tuft of silky hair at the base, 

 much flattened ; lowest glume linear, very acute, strongly con- 

 duplicate, with loug cilia on the keel below ; 2nd glume longer, 

 almost aristate, with hyaline margins, glabrous but for a few long 

 hairs on the back above ; 3rd glume much shorter, hyaline and 

 transparent ; terminal glume hyaline, deeply bifid, and with a bent 

 arm four times its length ; stamens 2.

 Kulutara, Dec. 1882. 



Near D. jnlodssiwa Trim. [Haplachne Presl). but with a stricter 

 habit, narrower leaves, and smaller and laxer spikelets with a 

 shorter tuft at the base ; the glumes are much more compressed 

 and glabrous, and the two lower more unequal. I have, however, 

 recently found at Labugama a form of D. piUmssima (var. glabra 

 Trim. ) with the glumes quite as glabrous as those of D. laxiuscula.
