clvii. gbamineje (Stapf). f Heteropogon. 
a secondary up to 6-rayed tier ; ultimate (simple) rays stoutly 
filiform, 2 to less than 1 in. long ; lowest subtending leaves like the 
preceding ones, the following becoming rapidly spathaceous with 
short blades. Spatheoles very narrow, very long-tapering to a slender 
point, from over 5 to 3 in. long, herbaceous to subherbaceous, glabrous, 
usually with impressed glands on the middle nerve or keel ; peduncle 
short during flowering, then lengthening out and sometimes only 
slightly shorter than the spatheole, filiform, appressedly hairy 
upwards. Racemes stout, compressed-cylindrical, 1-1J in. long, 
with 1-3 homogamous and up to 5 heterogamous pairs ; inter- 
nodes of the tough portion of the rhachis under 1 lin. long, glabrous : 
of the fertile portion (joints) up to over 14 lin. long, the free upper 
part J-f lin. long, widened upwards, obliquely truncate, whitish, 
glabrous, the part below (callus) as in II. contortus , 1 lin. long ; 
pedicels glabrous, J lin. long, disarticulating below the middle. 
Fertile spikelets linear-oblong, terete to subterete, 3J-3J- lin. long 
(excluding the callus), brown, at length very dark. Glumes equal, 
coriaceous ; lower tightly involute, truncate, minutely and ful- 
vously hirtellous. 7-9-nerved, nerves very fine, faintly visible in 
transmitted light with very few transverse nerves in the tips ; upper 
glume narrowly linear- oblong, subobtuse, glabrous or nearly so. 
Lower floret reduced to an oblong hyaline eciliate nerveless valve, 
1J lin. long. Upper floret $ or § : valve as in H. contortus , 3-5 
in. long ; valvule lanceolate, hyaline, nerveless, not quite 1 lin. long. 
Lodicules broad-cuneate, fleshy, j-f lin. long. Stamens 3 ; filaments 
not much longer than the ovary ; anthers oblong, purple, 4 lin. long 
or more or less reduced or the stamens quite suppressed. Stigmas 
exserted from the middle of the spikelet or higher up. Grain linear- 
oblong in outline, subterete, 3 lin. long, whitish. Male (or neuter) 
spikelets unequal, green, glabrous, the sessile of the homogamous 
pairs symmetrical, linear, acute, about 6 lin. long, their lower glume 
subherbaceous, very closely and finely nerved between the slightly 
scaberulous keels, indexed margins equal, very narrow ; upper glume 
slightly shorter, membranous, with 3 green nerves, ciliate upwards ; 
valves and stamens small, rudimentary ; the pedicelled of all pairs 
somewhat asymmetric, lanceolate, subulate-acuminate, 8-10 lin. long, 
usually more or less contorted ; glumes very unequal, lower her- 
baceous, very closely and finely nerved, with a narrowly winged 
keel and a fine indexed dap on one side, and with a keelless involute 
margin on the other, scrobiculate along a median zone ; upper glume 
as in the sessile homogamous spikelets ; valve of lower doret oblong, 
obtuse, up to over 4 lin. long, 1-nerved, ciliate, of upper doret linear, 
very narrow, up to 2 lin. long, nerveless, ciliate or both valves more or 
less (often much) reduced ; lodicules up to J lin. long ; anthers up 
to 2J lin. long or rudimentary. — Nash in North Amer. FI. xvii. 127.
