2. P. divaricatissimum (very dwarioate), JJ. Br. Prod. 192; BmtJi, M. 



Austr. vii. 467. Stems fcoma branching base sometimes under, sometimes' muct 

 above 1ft. high. Leaves glabrous or more or less pubescent or sqflly villous, the 

 ligula not prominent and not ciliate. igS'^^i'^l® °^ rather nmnerous rigidly: filiform 

 simple branches 8 to Sin. long, at first erect, at length spreading, the lower ones 

 in a dense verticil, the upper ones alternate and distant. Spikelets iii pairs or 

 rarely solitary along the branches, one sessile, the other pedicellate, 1 tq 1^ line 

 long, glabrous or covered with long silky hairs spreading when in fruit. Outer 

 glume very small, ovate, obtuse, the 2nd and 3rd nearly equal and both empty 

 or the 3rd rarely with a i:(}inute rudimentary palea, the 2nd usually 3- nerved, the 

 3rd 5-nerved. Fruiting glume ovoid, not gibbous, glabrous, smooth, acute. 



The following are given as more or loss distinct varieties of this species by B^nffi. in Fl. 

 Austr.: — 



1. glabtrrimum. Stems tall, branches of the panicle sometimes more thin 8hj..long, th« 

 whole plant glabrous. Spikelets J J line long, glabrous.

 Downs, Lmv, 



2. jmrmdle. l>'oliage glabrous of aeaily so. ramiole-iranohes 4 to Sin. long. Spikelets 

 li line long, silky-villous, rarely nearly glabrous. — Turn. Ag. Gaz. N.S.W, iv. PI. xx. 



Hab.: Keppel Bay, R. Drown. 



3. radiatum. Foliage softly villous. Spikelets small, gla'jious or nearly bo.— P. radtotuirt, 

 B. Br. Prod. 192. 



Hab.: Ballandool, loc/^f/cr ; Arm'adiHa, Barton, 



8. P, macractinium (rays of the verticil long), Beyitlu Fl. Austr. vii. 468. 

 Allied to P. divaricatissimum, but taller and quite glabroiis. Panicle similar, the 

 slender branches rigid, often 6 to Sin. but sometimes much longer, the lower ones 

 in a dense verticil, the upper ones alternate and distant. Spikelets distant in 

 pairs, one almost sessile, the pther on a longer pedicel, both fertile and similar, 

 narrow, acute, about IJ line long. Outer glume i to f line tong, ovate-oblong, 

 obtuse, the 2nd nearly as long as the Srd, 8 or 5-nerved, the margins ciliate, 

 the Srd rather longer, very prominently 8-nerved, ciliate with rigid hairs 

 proceeding from a row of promitient tubercles. Flowering glume narrow, acute.

4. P. papposum (furnished with pappus), /?. Br. Prod. 192 ; Benth. Fl. 

 Austr. vii. 468. Stems from a woolly or silky-villous rhizome 2ft, high or more. 

 Leaves flat, usually long and narrow, the lower ones softly pubescent, the upper 

 ones more glabrous ; ligula rather long, membrauoua. Panicle-branches 

 numerous, slender or filiform, spreading, 6 to Sin. long, the lower ones vertieilbte 

 the upper ones alternate and distant. Spikelets in distant pairs, both on capillary 

 pedicels, one pedicel much longer than the other but both long, sometimes 1 to 

 2iu. at the base of the branches, the upper pedicels shorter and sometimeir 

 solitary. Spikelets scarcely 1 line long, covered in the typical form with long 

 silky hairs spreading when in fruit. Outer glume minute or soiuetimes wanting, 

 2nd and Srd equal, 8-nerved, both empty or the third with a rudimentary paletf. 

 Fruiting glume rather acute, smooth and shining. 



Var. Uiostaehyam. Spikelets glabrous, otherwise quite similar.— P. autumnale, F, v. M.

5. P. sanguinale (bloody), Xm«. ; Kunth, Enum. i. 82 ; Benth. Fl, Aust7: 

 vii. 469. Summer Grass. Decumbent and often shortly creeping Sind rooting at 

 the base, ascending to 1 to Sft, or rather more. Leaves flaccid, flat, usually 

 pubescent and sprinkled with long bairs espeeially on the sheaths, but sometime?
