nearly .iflabrous. Spikea or paniole-branobes 3 to 8, crowded at the end of a long 

 peduncle, all from nearly the same point or shortly distant, 1^ to Sin. or in some 

 varieties about lin. long, the rhachis slender but angular, flexuose, scabrous- 

 ciliate. Spikelets in pairs, one nearly sessile the other pedicellate, oblong, 

 rather acute, about 1^ line long. Outer glume minute, rarely above J line long, 

 2ud glume lanceolate, 8-nerved. from ^ to f the length of the spikelet, 8rd glume 

 usually S-uerved, glabrous or ciliate, empty. Fruiting glume shorter, smooth.—

6. P. tenuissimum (very slender), Uenth. Fl. Austr. vii. 470. Erect, very 

 slender, much branched at the base, often above 1ft. high. Leaves short and 

 narrow, quite glabrous, the ligula short scarious and jagged. Spikes or panicle- 

 branches few, usually 3, filiform, spreading, distant, 1 to. l|in. long. Spikelets 

 in pairs, ovoid, quite glabrous, but little more than ^ line long, both pedicellate, 

 but one pedicel twice a? long as the other. Outer glume minute, almost micros- 

 copic, orbicular, the 2nd and Srd nearly equal, both fimpty, obtuse, membranous, 

 3 to 5-nerved. Fruiting glume rather acute, usually slightly exceeding the 

 empty ones.

7. P. parvlflorum (flowers small), E. Br. Prod; 192 ; Beiith, Fl. Austr. vii. 

 470. A tall but slender usually glabrous grass. Leaves long and narrow, the 

 ligula scarious, often long, jagged at the. end. Panicle branches from 2 to 

 numerous, spreading, simple, filiform,' 2 to 4in. or in some specimens 5 to 6in. 

 long, the lower ones distant, the upper ones often crowded. Spikelets ovoid, 

 glabrous, ^ to f line long, mostly in pairs along the flexuose rhachis, one on a 

 longer pedicel thaa the other ; but in the lower part of the branch often clustered,, 

 the longer padicel bearing 2 or 8 spikelets. Outer glume very small, ovate, 

 usually 1 -nerved, 2nd and Srd glumes nearly equal, both empty, membranous, 

 obtuse, the 2nd usually Sinewed, the Srd 5-nerved. Fruiting glume as long, 

 more acute, smooth. — Bail. 111. Mono. Gr. Q. i. , Turn. Ag. Gaz. N.S.W. ii.

8. P. Baileyi (after F. M. Bailey), Benth. FL Austr. vii. 471. A glabrous 

 rather slender grass of 1§ to 2ft., with the inflorescence oi P. parvijiorum, but the 

 spikelets rather of P. divaricatissimwn. Leaves flat, narrow, the ligula shortly 

 prominent, scarious, not ciliate. Panicle of several simple filiform branches of 3 

 or 4in., all distant or the upper ones rather crowded or the lower ones sometimes 

 clustered, not verticillSte. Spikelets narrow-ovoid, . rather acute, nearly 1 line 

 loBg, mostly in pairs, one on a much longer pedicel than the other, or in the 

 lower part of the branch the longer pedicel with 2 or. 3 spikelets. Ou't^r glume 

 very small, ovate, 1 -nerved, the 2^3 and Srd glumes nearly equal, fringed with 

 rather long hairs spreading when in fruit, the 2nd usually 5-nerved, the Srd 

 rather broader and 7-jnerved. Fruiting glume acute, smooth and shining.
