1. A. zeylanicus, Am. ; notofNees. Stems rather slender, ascending 

 or erect, slightly branched, 1 to 2 ft. high. Leaves narrow, obtuse or scarcely 

 pointed. Spikes simple and solitary on short terminal peduncles or in the 

 upper axils, 2 to 2^ in. long, slender. Sessile spikelets about 3 lines long, 

 narrow, the outer glumes very pointed, the awn of the flowering glume pro- 

 truding to about | in. Pedicel of the barren spikelet flat, ciliate on both 

 edges, the spikelet usually reduced to a single very pointed almost awned 

 glume. — A. pseudograya, Steud. Syn. Gram. 365. 



Hongkong, Wright ; at Araoy, and a var. with very hairy spikes at Whampoa, Hance ; 

 also in Ceylon. 



2. A. brevifolius, Sw.; Kunth, Mium. i. 488. Stems slender, decum- 

 bent, much branched, | to 1£ ft. long. Leaves narrow, 1 to 2 in. long, ob- 

 tuse or with a very short oblique point. Spikes solitary, very slender and 

 seldom above 1 in. long. Sessile spikelet not 2 lines long, the outer glume 

 not pointed, the awn of the flowering glume protruding about 4 lines. Barren 

 pedicel slender, not ciliate except at the base, bearing a small rudimentary 

 glume with a long awn-like point. 



Hongkong, Hance, Wright. On the adjacent continent, in Silhet, the Indian Archipe- 

 lago, and tropical America. 



3. A. montamis, Roxb. Fl. Ind. i. 267. Stems decumbent at the base, 

 branching and ascending to 3 or 4 ft. Leaves narrow, rather long. Panicles 

 terminal, very loose, about 4 in. long, with slender almost filiform clustered 

 branches of unequal length and little branched. Spikes not ^ in. long, all 

 pedicellate, consisting usually of 2 or 3 articulations, with a tuft of hairs at 

 each articulation and at the branches of the panicle. Sessile spikelet i\ in. 

 long. Outer glumes shortly ciliate. Flowering glume reduced to a fine 

 twisted awn 8 or 9 lines long. Pedicellate spikelet male and awnless, with 

 a few long hairs on the pedicel. — A. (Rhaphis) villosulus, Nees in Steud. Syn. 

 Gram. 397. A. parvispica (Rkapkis mic?'ostachya, Nees), Steud. I.e. Rha- 

 pJiis stricta, Nees in Kew Journ. Bot. ii. 99.

 and in the Philippines. 



4. A. Vachellii, Nees, PI. Meyen. 188. Stems and foliage of A. monta- 

 nns, but the panicle is longer, closer, and less branched, and the spikes, on 

 pedicels of \ to 1 in., are from 1 to 2 in. long, with numerous articulations. 

 Spikelets as in A. montanus, except that the pedicellate barren ones appear to 

 be always without stamens. — Chrysopogon strictus, Nees in Kew Journ. Bot. 

 ii. 95. 



Hongkong, Hance, Harland ; on roadsides at Aberdeen, Wilford. On the adjacent con • 

 tinent, and very nearly allied to the north Indian A. punctatus, Roxb. 



5. A. tropicus, Bpreng. ; Kuntli, Ennm. i. 503. Stems rather slender, 

 2 ft. or more, with a dense tuft of short hairs at the nodes. Leaves narrow, 

 rough at the edges. Panicle loose, 4 to 6 in. long, conspicuous for the rich 

 brown colour of the hairs of the glumes and pedicels ; the capillary branches 

 of unequal length, clustered and each bearing a single spike or the lower ones 

 slightly branched. Spikes usually about \ in. long, consisting of from 2 to 5 

 articulations, not so readily separable as in most species. Spikelets l? to 2
