Botanical description (B. F1., vii, 480).— 
Stems decumbent at the base, ascending to 6 or 8 inches in the smaller varieties, 
above 1 foot high in the larger ones. 
Leaves narrow. 
Spikelike panicle cylindrical, continuous or rarely interrupted, 4 to 1 inch, or in 
some varieties 2 inches long. 
Spikelets crowded, narrow, acuminate, and more or less curved, 1 to 1} or rarely 
2 lines long. 
Outer glume three-nerved, about half the length of the spikelet or rather more. 
Second glume curved and gibbous at the base, often ciliate, seven or nine nerved. 
Third glume the same length, but straighter and neither gibbous nor ciliate, with a 
small palea in its axil. 
Fruiting glume considerably shorter. 
Value as a fodder.—This is a moisture-loving grass, and hence 
valuable for cultivation or encouragement in very wet situations. We 
do not know much about its fodder value, but it 1s probably nutritious, 
like so many of its congeners. 
Habitat and range.—Usually found in swamps and moist situations. 
Extends from the Illawarra along the Coast districts to Queensland 
and Northern Australia. It is also widely dispersed over tropical 
Asia and Africa. 
Serres VI.—PAnicuLatas. 
Panicle-branches usually more or less divided. Spikelets all pedi- 
cellate (except sometimes the first three species and a Queensland one, 
P. inxquale). 
Panicle-branches scarcely divided; spikelets few, rarely more 
numerous, scarcely under 2 lines long ; no male flowers. 
Spikelets nearly or sometimes quite sessile (species approaching 
the Paspaloidec).
