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

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

 truding to about i in. Pedicel of the ban-en spikelet flat, ciliate on both 

 edges, the spikele"t usually reduced to a single very pointed almost awned 

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

3. A. montanus, Uoxh. Tl. hid. 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

 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 1-^ in. 

 long. Outer glumes shortly ciliate. Plowering 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.—^. (Rhaphis) villomlus, Nees in Steud. Syn. 

 Gram. 397. A. parvisplca {Rhaphis microstachya, Nees), Steud. I.e. Rha-

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

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

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

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

 be always without stamens. — Chrysopogou strict us, Nees in Kew Journ. Bot. 

 ii. 95. 



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