 473. Stems from & branching base, erect, slender, mostly under 1ft. high, more 

 or less hairy as well as the foliage. Leaves short, narrow, acute, very spreading, 

 the nerve-like margins usually undulate. Panicle of few (4 to 6) erect si^jple 

 distant branches, the longest about |in. long. Spikelets usually 5 or 6, alternate, 

 under 1^ line long but appearing longer from the long shining silvery-silky hairs 

 with which they are covered. Outer glume acute, more than half the 'length of 

 the spike, 2nd glume acute, mucronate, 8-nerved towards the end, 8rd glume 

 nearly similar and empty but rather longer, Srnerved at the end, with a longer 

 point ; fruiting glume,^. much shorter, glabrous, distinctly 8-nerved at the wdf 

 with a short point, atlength hardened and minutely striate, — Kunth, Be v. Gram.

14. P. flavidum , (yellow), Retz. Obs, iv. 15; Bsnth. Fl. Austr. vii. 474. 

 Warrego Summer G^rass. Stems erect, branching at the base, rather ri^rid, 

 attaining 1 to 2ft. or rftther more. Leaves acute, sometimes rather broad but the 

 margins involute when dry, glabrous except a few short hairs at the orifice of the 

 sheath. Panicle of several often numerous erect distant branches, or sessile 

 spikes, the lowest sometimes above ^in. long, the upper one shorter, the rha^bis 

 flexuose, slightly dilated. Spikelets sessile in about 2 rows, in the typical form 

 very oblique, ovoid, about IJ line long or rather niore in some specimens. 

 Outer glume very short, broad and obtuse, the second glume the largest, 

 broad, several -nerved, very concave and incurved, the third smaller, flat on the 

 back, enclosing a palea large and broad in the typical form but no stamens. 

 Flowering glumes usUally shortly acuminate. — R. Br. Prod. 190 ; Dulhie Ind.

 usually very small, the fruiting glume very rugoie. — Turn. Ag. Gaz. N.S.W. iv. PI. xii,

15. P. gracile (^lender), 11. Br. Prod. 190 ; Bmtk. FL Austr. vii. 476. 

 Erect, .much branched towards the base, quite glabrous, usually slender, from 

 under 1ft. to above l^ft. high, but exceedingly variable in siature and aspect. 

 Leaves from very narrow to rather broad. Panicle usually long and slender, the 

 branches or sessile spikes or clusters erect, distant, the lower ones 3 to 4 lii|es 

 or rarely i to lin. long, the upper ones smaller, often reduced to short clusters 

 or to single spikelets towards the end of the panicle, the rhachis of the br4ncbes 

 often but not always produced beyond the last spikelet into a point sometiines at 

 long as the spikelet. Spikelets singly sessile or in pairs, one pedicellate tHe qt^ier 

 sessile along the rhachis, rarely more or less distinctly in 2 rows almost as in P. 

 flavidum, ovoid, 1 to If line long, nearly straight, the outer glume, ovate acute, 

 rather less or more than half as long as the spikelet, the second and third nearly 

 equal, both empty membranous and about 5-nerved, fruiting glume as, long or 

 rather longer, minutely transversely rugose. — Turn. Ag. Gaz. N.S.W. iii. PI. xxi,
