238 XXVIII. (iRAMiNE.K. [Fragvostis 



oblong to narrow-lanceolate, greenish-brown ; fertile glumes rigid, 

 subacute, lateral nerves very strong, keel inconspicuously sca- 

 bridulous below the apex, ovate-lanceolate when flattened ; pale 

 persistent, slightly shorter, keels strong, scabrid and long-ciliate, 

 back narrowly elliptical, apex truncate ; grain narrow, more than 

 3 times as long as broad, tapering above the basilateral hilum 

 to the blunt apex, reddish-brown, smooth. 



Plants about 4 ft. high, internodes (excepting the flowering) 

 from ^ in. to 1 ft., and 2i to 8^ in. respectively on the two culms 

 present, lowest internode 1]- line in diameter ; leaf -sheaths 3 to 

 5 in., blades to 10 in. long, with a breadth at the base exceeding 

 2 lines. Panicle reaching a foot in length by nearly 9 in. across ; 

 lower branches 6 in. long ; spikelets ^ to ^ in. long by 1^ to nearly 



2 lines across ; pedicels 1 to 6 lines long ; barren glumes fallen ; 

 fertile glumes If line long; anthers a good ^ line; grain f line. 



Resembles E. tremula Hochst. in habit, but is a very distinct 

 species characterised by the broader spikelets, subacute glumes, 

 and large narrow grain.

The dedication of this fine species to Mr. Hiern needs no 

 explanation. 



15. E. passa Rendle sp. nov. 



Apparently perennial with a slender creeping rhizome ; culms 

 csespitose, branched, weak, slendei-, internodes 3 to 4, subterete, 

 polished, except the vippermost which bears the inflorescence 

 not elongated ; nodes brown, glabrous ; lower sheaths exceed- 

 ing or subequal to the internodes, weak, loose, membranous, 

 subcompressed, glabrous except for a few hairs at the mouth ; 

 ligule short, densely hairy ; leaves weak, flat, linear, tapering both 

 to the base and the fine acute apex, glabrous, scabridulous, veins 



3 to 5, subprominent below ; panicle large, especially for the 

 size of the plant, ovoid, efiuse, chstant- flowered, glabrous, branches 

 filiform, opposite or scattered, ultimately widely spreading, often 

 horizontally, bearing at about equal distances from the base 

 upwards capillary widely spreading branchlets which in the 

 lower part of the panicle may branch again, but otherwise 

 bear directly the long-stalked spikelets; the latter pale green, 

 subcompressed, lanceolate to oblong-lanceolate, 4- to 6-flowered, 

 barren glumes subhyaline, acute, 1-nerved, carinulate and 

 scabridulous in the upper two-thirds, reaching about half-way up 

 the next fertile glumes, the lower lanceolate, somewhat shorter 

 than the upper which is ovate ; fertile glume shortly ovate, blunt, 

 3-nerved, lateral nerves submarginal and curved, falling short 

 of the apex ; pale persistent, scarcely shorter, included, upper third 

 of keels obscurely ciliolate ; anthers pale brown, short ; grain 

 I'ed, rugulose, subrhomboidal tapering slightly towards the base, 

 hilum occupying about half the ventral face, the back rounded 

 and with a well-marked longitudinal median groove.
