47. P. manicatum, $ tayf. Annual, up to over 4 ft. high. Culms 
slender, very compressible, erect, many-noded, simple and erect or 
suberect for about 8 internodes (2J ft.), then branching in tiers or 
fascicles, the main culm and the very slender to filiform branches 
repeatedly geniculate, only the last internode (peduncle) erect, culm 
and branches glabrous and smooth, internodes mostly bared by the 
breaking or slipping off of the sheaths, the upper channelled. Leaf- 
sheaths shorter than or more rarely as long as the internode, striate, 
more or less loosely hirsute or glabrous, the lower and intermediate 
swollen and sulcate- striate at the nodes, the swollen portion remain- 
ing as a ring covering the stem-node after the fall of the sheath ; 
ligules membranous, very short, rounded, ciliolate ; blades linear 
from a slightly constricted base, long-tapering to a slender point, 
1J-2 in. by 1J lin., flat, thin, green, glabrous except for some tubercle- 
based cilia near the base, margins scaberulous, closely nerved, midrib 
and primary lateral nerves hardly differentiated . Panicles erect , ab out 
3 in. long, mature subfastigiate, obovate-oblong, glabrous, divided 
to the third or here and there the fourth degree, all the divisions 
finely filiform, angular or terete upwards, minutely scaberulous ; 
primary axis very slender, terete below, angular above ; primary 
branches solitary or approximate in pairs or false whorls, permanently 
obliquely erect rarely at length more spreading at an angle of up to 
45°, very loosely divided from low down for up to 6 lin. ; branchlets 
forming very lax 4-2-spiculate or downwards compound and then 
up to over 6-spiculate racemes ; pedicels contracted, capillary, very 
unequal, quite short to up to 4 lin. long, tips minutely cupular. 
Spikelets lanceolate-oblong, apiculate-acuminate, soon gaping, 
about 1 J lin. long, green, variegated with purple, glabrous. Glumes 
dissimilar ; lower ovate, mucronate-acuminate, half to two-thirds the 
length of the spikelet, subhyaline, with an excurrent midnerve' and 1 or 
2 minute obscure side-nerves on each side ; upper glume correspond- 
ing in size and outline to the spikelet, broadly rounded on the back, 
prominently 7-nerved, tip contracted and usually dark. Lower 
floret g : valve like the upper glume ; valvule oblong, subacute, 
flaps much widened downwards ; anthers \ lin. long. Upper floret 
oblong, obtuse, £ lin. long, greyish-white, very smooth and glossy ; 
valve and valvule thinly crustaceous.
