allied species. SpikeJefcs 2| to 3 lines long, the 2 prominent nerves of the outer 

 glume almost winged, with 8 to 5 less conspicuous nerves between them. Awns 

 i to lin. long.— Hook. Ic. PL, 1869. 

 Hab.: Thursday Island. 



9. A. lanatus (woolly), E. Br. Prod. 202 ; Benth. Fl. Austr. vii. 538. An 

 erect grass of 2 or 3ft. or more, with the habit inflorescence and erect spikes of 

 A. exaltat'Us, bub the leaves, though narrow usually flat, and the spikes very 

 densely woolly-hairy almost as in ^. bombycinus. Awns \ to lin. long.

 Bay, Dallachy; Mount Wheeler, Thozet. 



10. A. bombycinus (inflorescence resembles masses of silk), R. Br. Prod. 

 202; Benth. Fl. Austr. vii. 538. An erect rigid perennial grass of 1^ to 8ft., 

 usually glabrous except a little silky pubescence on the lower leaf-sheaths, 

 the nodes glabrous or shortly bearded. Leaves narrow, flat, rather rigid, the 

 ligula very prominent, entire. Panicle shortly branched, 3 to 6in. long, with 

 sheathing bracts of 1 to 2in. under the branches. Peduncles usually shorter 

 than the bracts, bearing each a narrow sheathing bract and 2 very densely 

 woolly-hairy spikes of ^ to lin., at first erect but soon spreading or reflexed. 

 Sessile spikelets 2 to 5, concealed by the silvery-silky hairs. Outer glumes acute, 

 many-nerved but the 2 lateral nerves much more prominent, especially as the 

 flowering advances and the intermediate ones becoming almost obliterated or 

 visible only towards the end of the glume ; 2nd glume thin, with a prominent 

 keel produced into a short point, 3rd very thin, faintly 3-nerved ; terminal 

 flowering glume very thin and hyaline, shortly bifid, with a very fine awn scarcely 

 exceeding the spikelet, or entire without any awn. Pedicellate spikelets reduced 

 to a single narrow many-nerved glume of 2-|- to 3 lines. — Bail. 111. Mono. Gr. Q. i.

 sure, Wuth. 



The densely silky-woolly spreading spikes and very short awn, readily distinguish this from 

 the three preceding species. 



11. A.. STardus (Nardus-like), var. grandis, Hack. DC. Mono. Phanero. vii. 

 605. Stems erect, not very stout, 2 to 5ft. high. Leaves narrow, flat, glabrous, the 

 ligula prominent and scarious. Panicle varying from short and dense to 1 or 

 l^ft. long and loose but narrow, the lanceolate sheathing acute bracts under each 

 branch mostly exceeding the spikes. Peduncles solitary within the last bract, 

 each bearing a narrow, sheathing bract and 2 sessile spikes, at first erect at length 

 spreading, J to fin. long, the rhachis and pedicels hairy, but the hairs short not 

 covering the spikelets as in the preceding species. Sessile spikelets 3 to 5, about 

 2^ lines long; outer glume about 5-nerved, the 2 lateral nerves very prominent 

 towards the end ; 2nd glume thin, rigid, slightly keeled, with hyaline ciliate 

 margins, 8rd very thin, hyaline and ciliate ; terminal or flowering glume very 

 narrow, hyaline, bifid, with a fine awn about twice as long as the spikelet. 

 Pedicellate spikelet reduced to empty glumes, the outer one many-nerved. —

 Widely spread over tropical Asia. 



12. A., refractus (broken), R. Br. Prod. 202; Benth. Fl. Austi. vii. 534. 

 A glabrous erect grass of about 3ft., with the narrow leaves paniculate 

 ihflorescence and sheathing bracts of the preceding species, and the spikes similarly 

 2 together about ^in. long on short bracteate peduncles, but much more divaricate, 

 soon reflexed, and glabrous except a small tuft of short hairs at the base, of the 

 sessile spikelets. Sessile spikelets 2 to 5, 2J to 3 lines long ; outer glume acute.
