1864 OLIII. GRAMINEiE. [Andropogon 



5. A. annulatus (ringed), Forsk. ; Kunth, Enum. i. 498 ; Benth. Fl. Austr. 

 vii. 531. Stems from a tufted base ascending to about 2ft., the nodes glabrous 

 or slightly bearded. Leaves narrow, usually glaucous. Spikes 2 or 3, nearly 

 sessile at the end of the peduncle without sheathing bracts, 1^ to 2in. long, the 

 pedicels and base of the sessile spikelets much less ciliate than in the preceding 

 species. Spikelets about 2 lines long. Outer glume of the sessile one membranous, 

 prominently many-nerved, obtuse or 3-toothed, ciliate on the margin and with a 

 few long hairs on the back at the top ; 2nd glume thin, the midrib alone 

 prominent, 3rd very thin and hyaline ; awn or terminal glume ^ to fin. long, 

 without any hyaline dilatation at the base. Pedicellate spikelet nearly similar 

 but awnless, and with a male flower or reduced to empty glumes. — Duthie Ind. 

 Gr. PI. XX. 



Hab.: Ipswich and other southern localities ; Kockhampton. 

 Widely spread over tropical Asia and Africa. 



Var. monostachya. Spike single. Sessile spikelets rather longer than in the typical form, 

 the outer glume with fewer nerves and much more ciliate with long hairs. 

 Hab. : Nerkool Creek, Bowman. 



6. A., intermedius (intermediate), R. Br. Prod. 202 ; Benth. Fl. Austr. vii. 



531. An erect grass of 2ft. or more, branching and leafy at the base, the 

 nodes varying with or without beards. Leaves narrow. Spikes slender, 1 to 

 IJm. long, usually numerous, all shortly pedicellate in an oblong terminal paoiole 

 of 3 or 4in. without sheathing bracts, the common rhachis glabrous and always 

 more or less elongated, the pedicels and base of the sessile spikelets more or less 

 ciliate. Spikelets under 2 lines long, narrow and acute or scarcely obtuse and 

 often purplish. Outer glume often, but not always even in the same spike, 

 marked with a dorsal pit as in A. pertusus. A.wn small and slender. Pedicel- 

 late spikelet developed and often enclosing a male flower. — A. inundatus, P. v. M. 

 in Linnffia, xxv. 444. 



Hab.: Keppel Bay, JS. Brown; Port Denison, Fitzalan; Brisbane River, Moreton Bay, 

 F. V. ilueller, Bailey ; Kockhampton and numerous localities in the south, Thozet, Bowman 

 and others. 



7. A., procerus (very tall), R, Br. Prod. 202; Benth. Fl. Austr. vii. 



532. Stems stout, erect, 8 to 5ft. high or even more. Leaves long, the lower 

 ones i to ^in. broad with long sheaths, all glabrous, the ligula broad and jagge<l. 

 Panicle 6in. to above 1ft. long, narrow, dense, with very numerous short branches, 

 the linear acuminate erect sheathing bracts mostly longer than the spikes. 

 Peduncles short, erect with a sheathing bract about the middle and 2 erect spikes 

 rarely ^in. long, the long white hairs concealing the spikelets. Sessile spikelets 

 usually 3, narrow, scarcely 2 lines long ; outer glume flattened on the back with 

 2 prominent nerves not far from the margin and usually 3 fainter ones betweeu 

 them ; the 2nd glume narrow, keeled and pointed, 3rd short, very thin and 

 hyaline ; awn or terminal glume usually above ^in. long with a narrow bifid 

 hyaline base. Outer glume of the. barren pedicellate spikelets many-nerved. 



Hab.: Groote Islands, G. Brown, 



This and the two following species are certainly very closely allied, but the differences chiefly 

 in foliage appear to be constant. A. procerui is aXso remarkable for its smaller spikelets, A. 

 lanatus for the denser wool of the spikes, all three differ from A. bombyciims in their erect 

 spikes and much longer awna.^B«ntft. 



8. A. exaltatus (tall), R. Br. Prod. 202 ; Benth. Fl. Austr. vii. 582. Stems 

 erect, scarcely 1ft. high to above 8ft. Leaves very narrow, all ending in long subu- 

 late points and in the smaller specimens subulate from the sheath, the ligula long 

 and scarious. Nodes usually glabrous. Panicle sometimes short and dense, some- 

 times long and interrupted. Spikes 2 or very rarely 3 together, | to lin. long, 

 erect, densely hairy, the common peduncles short with a sheathing bract as in the
