54. P. pansum, Rendle in Cat. Afr. PI. Welw. ii. 177. Annual, 
tufted from a subgeniculate base, simple, 2-noded with the uppermost 
internode long-exserted and occupying much more than half the 
culm. Leaf-sheaths terete, tight, prominently striate, the lowest 
less than 1 in., the following 1J-2J in. long, loosely and scantily 
hirsute in the upper part with tubercle-based hairs, margins ciliolate ; 
ligule a short ciliolate rim ; blades linear from a slightly rounded 
base, tapering to a slender slightly callous point, 2-8 in. by 2-J — 3 lin., 
flat, rigidly suberect or oblique, drying yellowish, finely hirsute with 
minutely tubercle-based hairs along the midrib and on the nerves 
on the lower face and the margins, and less or more irregularly so 
on the upper, the hairs often deciduous, leaving the tubercles behind, 
midrib very slender, lateral nerves fine, prominent and very close, 
not differentiated. Panicles erect, long-exserted, ovate to broad- 
oblong in outline, from \ to over 1J ft. long, very loose and open, 
divided to the third or fourth degree ; common axis slender, terete to 
angular, smooth below, like all its divisions scaberulous upwards, 
internodes irregularly long (to over 1J in.) and short ; primary 
branches ascending, somewhat flexuous, solitary or here and there 
(particularly the intermediate) paired, very long, finely filiform, 
remotely divided from near the base or higher up, longest internodes 
up to 1 in. long, the following divisions capillary, the ultimate bearing 
the spikelets mostly in pairs near their tips ; pedicels with minute 
discoid tips, the lower of a pair often very short, the upper 1-1 £ lin. 
long, those of solitary spikelets up to 6 lin. long. Spikelets ovate to 
ovate-oblong, shortly acute, 1J lin. long, drying a golden-brown. 
Glumes membranous, glabrous, very finely but prominently nerved, at 
least upwards ; lower lanceolate and acutely acuminate in profile, 
half to three-quarters the length of the spikelet, 3-5-nerved ; upper 
broader and less acuminate, acute, 5-7-nerved. Lower floret 
barren : valve very similar to the upper glume and as long, 7-9- 
nerved ; valvule much reduced (to half or less than the length of the 
valve), ovate, with the flaps evanescent above the middle. 
Upper floret elliptic- oblong, obtuse, up to 1 lin. long, brown, 
polished.
