238 XXVIII. GRAMINEE. [Zragrostis 
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 3 in. to 1 ft., and 23 to 83 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 4 to $ in. long by 13 to nearly 
2 lines across; pedicels 1 to 6 lines long; barren glumes fallen ; 
fertile glumes 12 line long; anthers a good 3 line; grain 2 line. 
Resembles Z. 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 
cespitose, branched, weak, slender, internodes 3 to 4, subterete, 
polished, except the uppermost 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, effuse, distant-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 
red, 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.
