21. P. piligerum (bearing hairs), F. r. M.; Benth. Fl. Amtr. vii. 477. 

 Closely resembles some of the longer more hairy spaoimeris of P. helnpus. Leaves 

 rather narrow, 6 to Sin. long. Panicle of 3 to 5 erect simple branches 1 to near 

 2in. long. Spikelets ovoid, acute, nearly 2 lines long, alternate along the 

 rbachjs but rather distant so as to appear in a single ro\y, Glumes hairy,, the 

 outer one short, 3-n6rvCd i 2nd and 3rd-glume 5-mryeA, the 3rd' rather narrower 

 than the 2nd but hgth empty and equal in lewgth. Fruiting glume shorter, 

 coriaceous, bbtuse, without any or only a Very minute and de'ciduous terminal 

 point, minutely transversely ru^oSe. ' .

 vii. 478. Stems decumbent or creeping and ' rooting at the, lowey nodes, slender 

 and ascending to 1ft. or rather more. Leaves flat, glabrous or ^with a few hairs' 

 especially at the orifice of the sheaths. Panicle; of few (usually 2 tb ' 4 but". 



occasionally 6 or 7) distant simple seound branches 1 to 2in. long, at first erect, 

 at length spreadingor reflexed, the! rhachis slender or slightly dilated, often 

 sprinided with a few hairs. Spikelets sometimes loosely alternate along the, 

 rhachis almost in a single row, sometimes more riuraerous and a[jpi;oximate in 2 

 distinct rows, sessile or' shortly sti'pitate, ovoid, rather acute, li line long, quite 

 glabrous. Outer glume scarcely half'the length of' the spikelet, thin, very broad, 

 the margins overlapping' each other, 2ild. and 3rd , glumes nearly equal, 

 prominently S-nerved ; -a narrow .palea in the 8rd. Fruiting glume nearly- as 

 long, very obtuse, hardened but the three nerves very visible. — ^^Bail. 111. Mono.

 vii. 478. A weak glabrous rather, glaucous much-branched grass.- Leaves long, 

 and narrow. Panicle usually, of 3 or 4 simple distant branches, at first erect but • 

 soon spreading, and at length reflexed like those of P. distachyvm, but therhaqhisi 

 generally though not always dilated, produced into a rigid point beyond the last 

 spikelet, and bearing under the lowest spikelet ,a rigid linear bristle (an abortive 

 branch ?) as long as the spikelet. Spikelets not numerous, alternate and distant 

 along the rhachis so as tq appear in one row, ovoid-oblong, fully 2 lines long in 

 some specimens, rathe'r imder in some others. . Outer glumb 3-ner'ved, obtuse, 

 at least f the length of the spikelet, 2nd and 3rd glumes equal,"many-rierved, 

 usually both empty but sometimes with a palea in the 3rd. Fruiting glume 

 hardened as in the genus. — Maid. Gr. N.S.W. 37. .
