spikelets £ or neuter, with rudimentary anthers, lanceolate to 
linear-lanceolate, glabrous or loosely hairy ; lower glume produced 
into a bristle up to 2 lin. long, closely 11-13-nerved, keels rigidly 
ciliolate above ; upper glume acute, 3-nerved, erect-ciliate ; valves

The Mascarene specimens referred to this species by Iiackel are H. rufa, 
whilst the Indian also quoted by Hackel,l.c. {Griffith, 6766), is clearly a distinct 
species of Hyparrhenia. 
2. H. gazensis* Stapf. Perennial, tall. Culms ascending, rooting 
from the lower nodes, terete, stout, glabrous, smooth. Leaf-sheaths 
terete, glabrous or hirsute upwards and along the margins, the upper 
much shorter than the inter nodes ; ligules scarious, truncate, up 
to 1 lin. long, glabrous or pubescent ; blades linear, slightly con- 
stricted at the base, long attenuated to a fine point, up to 1 ft. by 
over 4 lin., green, glabrous or sparingly hairy, scabrid along the 
margins, otherwise smooth or slightly rough ; midrib comparatively 
slender, whitish above, prominent below, primary lateral nerves 
3-4 on each side. Spatheate panicle very lax, leafy, up to almost 
2 ft. long, sometimes overtopped by the uppermost blades ; primary 
internodes up to 10, the lowest 6-4 in. long, the upper rapidly 
decreasing ; lowest tiers of 1 or 2 compound rays, f-1 ft. long 
and 2-3-noded, the following up to 6-rayed, mixed or simple ; simple 
rays 1-1-| in. long, finely filiform ; subtending leaves developed almost 
throughout as normal leaves with shortened sheaths and long blades. 
Spatheoles obliquely erect or spreading, lanceolate, acutely acuminate, 
1-lf in. long, 1-1 \ lin. wide, thinly scarious, reddish or brownish, 
glabrous, the margins at length slightly involute ; peduncles fili- 
form, 7-9 lin. long, straight and enclosed in the spatheoles, very 
slender, filiform, pubescent below with some longer delicate white 
hairs. Racemes subparallel or only slightly spreading or finally 
the lower somewhat deflexed, 6-7 lin. long, laterally exserted from 
the spatheoles, greenish or reddish, sparingly silky, 4-awned per pair, 
the lower subsessile, the other with a very slender base, up to over 
1J lin. long, both bases more or less hairy, with oblique shortly
