Panicum. j clvii. gramine.® (Stapf). 665 
panicle, obliquely spreading or more erect, flexuous or somewhat 
stiff, filiform, quite terete and smooth, divided again from low down, 
with the ultimate divisions rather contracted and capillary ; the 
rather short pedicels slightly unequal and mostly 1-1 J lin. long, their 
tips discoid. Spikelets elliptic-oblong, subacute, about 1 lin. long, 
olive- or brownish-green, here and there with a faint metallic lustre, 
quite glabrous. Glumes membranous, finely and here and there 
prominently nerved, subobtuse, the lower narrower in profile, three- 
quarters the length of the spikelet or only slightly shorter than the 
spikelet, 3-nerved, upper much broader, deeply concave, 5-nerved. 
Lower floret g : valve very similar to the upper glume ; valvule 
slightly shorter, keels faintly scaberulous ; anthers § lin. long. 
Upper floret oblong, subacute, § lin. by J lin., whitish ; valve and 
valvule very thinly papery, quite smooth or with a few extremely 
minute warts ; anthers slightly smaller than in the g floret. —

15. P. carinifolium, Stapf. Perennial from a short premorse 
rhizome, 4-5 ft. high, with intravaginal innovations. Culms erect, 
straight and stiff, simple, terete, somewhat robust, about 6-noded, 
only the upper internodes exserted from the sheaths. Leaf-sheaths 
tight or at length involute upwards and slipping from the culm, 
terete, firm, glabrous except along the upper ciliate margins, striate ; 
ligule reduced to a rim or transverse line ; blades linear, the lower 
from a very long and gradually attenuated, the upper from an equally 
wide base, tapering upwards to a long fine point, up to over 1 ft. long 
and 3 lin. wide, suberect, rather rigid, the lower flat above the attenu- 
ated base which is more or less channelled and with narrow and 
upwards often recurved margins, quite glabrous, smooth except 
along the scabrid margins, midrib prominent below and rather stout 
in the lower leaves, primary lateral nerves indistinctly differentiated 
below, obscure like all the nerves above. Panicle oblong to ovate- 
or lanceolate-oblong in outline, stiffly erect, 4-5 in. by 1-2 in., moder- 
ately open and loose, divided to the third or fourth degree ; common 
axis slender, terete or subangular, smooth, lowest internodes J to 
over 1 in. long ; lower primary branches solitary, divided some 
distance from or at the base, in the latter case sometimes forming very 
unequal false whorls, the longest rarely more than half the length 
of the panicle, filiform, scaberulous, rather stiff and obliquely erect : 
secondary branchlets divided from the base with their basal divisions 
crowded in fascicles ; ultimate divisions capillary, rather short and 
somewhat contracted ; pedicels unequal, 2 lin. long, smooth 
upwards, tips discoid. Spikelets very broadly elliptic to rotundate 
in outline, obtuse, somewhat turgid, slightly over f lin. long, pale
