82. P. Beccabunga, Rendle in Cat. Afr. PI. Welw. ii. 179. A 
straggling perennial with long-trailing culms, rooting at the nodes, 
the very slender rhizome dying off behind. Culms filiform, many- 
noded, the internodes hardly over 9 lin. long, terete, smooth, glabrous, 
long-exserted. Leaf-sheaths tight, up to 4 lin. long, finely striate, 
quite glabrous and smooth ; ligule reduced to a narrow membranous 
rim ; blades narrowly ovate to lanceolate from a rounded clasping 
base, acute or acutely acuminate, 4-9 lin. by 2-3 lin., flat, firm, 
obliquely spreading, quite glabrous, smooth, midrib and primary 
lateral nerves (2-3 on each side) very fine with 3-4 indistinct secondary 
nerves in the intervals, connected by cross-veins. Panicles very 
shortly exserted, erect, ovate in outline, from 6-9 lin. long and 4-5 
lin. wide, rigidly and moderately open, divided to the second, rarely 
the third degree ; common axis slightly angular, quite smooth, 
internodes irregularly short and long, 1-2 lin. long ; primary 
branches spreading at 45°-60°, bearing from near the base about 
6 solitary spikelets ; branches and pedicels fine, terete, smooth and 
glabrous, the pedicels from less than J-l lin. long. Spikelets 
elliptic-oblong, obtuse, almost 1 lin. long, somewhat plump, quite 
smooth. Glumes thinly membranous, finely but distinctly nerved, 
unequal ; lower broad-ovate, subacute, over half to two-thirds the 
length of the spikelet, 3-nerved ; upper corresponding to the spikelet 
in length and outline, 5-nerved. Lower floret $ (?) : valve like 
the upper glume ; valvule slightly shorter, oblong, with minutely 
scaberulous keels. Upper floret broadly elliptic-oblong in outline, 
obtuse, f lin. long, polished, white ; valve and valvule subcoriaceous.
