1866 OLIII. GRAMINEJ5 [Andropogon. 



many-nerved ; 2nd narrow and keeled, 3rd thin and hyaline ; terminal or 

 flowering glume hyaline, narrow, either 2-lobed with an awn slightly exceeding 

 the spikelet, or more frequently entire or nearly so and awnless. Pedicellate 

 spikelets neuter or rarely with a male flower, the outer glume many-nerved. —

13. A. filipendulus (drooping threads), Hack, in Fl. xxix. 115 ; Hook, in 

 FL. Brit. Ind. vii. 203. Stems rather slender, erect, about 2ft. high. Leaves 

 narrow, glabrous or sprinkled with long hairs. Nodes not bearded. Panicle 

 looser than in the preceeding species with slender but not very long bramches 

 solitary or clustered within sheathing bracts or floral leaves. Peduncles exceed- 

 ing the last sheathing bracts bearing each 2 spikes but not digitate, one attached 

 lower down than the other, each ^ to fin. long without the awns. Sessile 

 spikelets 3 or 4, the lowest sometimes containing only a male flower, the others 

 with a hermaphrodite flower, 2 to 2J lines long, slightly hairy. Outer glume 

 obtuse, about 9-nerved, 2nd rather shorter, obtuse, 3-nerved, Srd very narrow, 

 thin and hyaline ; awn or terminal glume on a short filiform base, 1 to 2in. long, 

 the lower part rigid and hirsute with rufous hairs. Pedicellate spikelets narrow, 

 acute, 2J to 3 lines long, usually containing a male flower, the outer glume many- 

 nerved, often produced into a fine point. — A. procerus, F. v. M. Fragm. viii. 121, 

 not of R. Brown ; A. lachnatherus, Benth. Fl. Austr. vii. 534. 



Hab.: Islands ot Moreton Bay, F. v. Uueller; Brisbane River, Bailey; Rookhampton, 

 O'Shanesy ; Nerkool Creek, Bowman. 



14. A. fragilis (fragile), R. Br. Prod. 202 ; Benth. Fl. Austr. vii. 535. A 

 slender decumbent much-branched grass, attaining sometimes 2ft. or more, 

 usually glabrous. Leaves narrow, rather short, the upper ones passing into 

 sheathing bracts. Panicle leafy, slender, secund, consisting of few spikes on 

 very unequal slender peduncles, each with a narrow acute sheathing bract below 

 the spike. Spike slender, 1 to IJin. long, with a short hyaline, obscurely cup- 

 shaped bract enclosing each notch. Sessile spikelets about 2 lines long, very 

 narrow ; outer glume rigid but thin, faintly-nerved, the 2 lateral nerves more 

 prominent, 2nd glume keeled, acute, 3rd very thin and hyaline ; terminal glume 

 thin and hyaline, divided almost to the base into 2 narrow lobes, the awn 

 between them shortly exserted. Pedicellate spikelets reduced to a single narrow 

 empty glume, tapering into a fine awn, or sometimes in the terminal spikelets 

 acute only. 



Hab.: Endeavour River, Banks and Solander, and ottier tropical localities. 



46. CHRYSOPOGON, Trin. 

 (Hairs under the spikelet often of a golden colour.) 

 (Holous, B. Br. partly.) 

 Fertile spikelets 1 -flowered, sessile between 2 pedicellate male or barren spike- 

 lets at the end of the filiform unequal simple or divided branches of a terminal 

 panicle, with sometimes 1 to 3 pairs of spikelets on the branch below the 

 terminal 8. Glumes of the fertile spikelets 4, the outer one the largest, awnless, 

 membranous and many-nerved, or more rigid with the lateral nerves prominent 

 and often muricate ; 2nd glume narrow, keeled, pointed or produced into a fine 

 straight awn ; Srd much smaller, very thin and hyaline ; 4th or terminal glume 

 under the flower slender, flexuose and stipes-like at the base, or dilated hyaline 

 and 2-lobed, with a short or long awn terminal or from between the lobes, 

 twisted in the lower half and bent back above the middle as in Andropogon.
