139. GRAMINE.E. [19. Tripogon. 



striate and with about 3 fine raised nerves, blades often curved. 

 Spike 1^" long very slender, rhachis flattened with rounded back. 

 Spikelets •07--08" long erect, close-set. Gl. i and ii subequal, as 

 long as spkt. with a very narrow opaque center looking like a double 

 nerve and hyaline margins, linear-lane, acute ; iii on very minute 

 rhachilla, about three -fourths to four-fifths as long as i and its palea 

 villous (nerveless, F.B.I., but both it and its palea appear to me 2- 

 nerved). 



Gya, Mokim ! It usually grows on old walls according to RoxLiirffJi. 



18. GRACILEA, Koen. 



Small grasses with short leaves. Spikelets in deciduous clusters 

 which are secund and jointed on the filiform flexuous rhachis. Upper 

 spikelets in the cluster sometimes imperfect. Rhachilla not jointed 

 at the base, sometimes produced between the glumes and beyond 

 the last imperfect glume and bearing empty glumes. Glumes 4-6 

 altogether, i narrow rigid long-ciliate, produced into a long rigid scabrid 

 awTi ; ii broader with broad hyaline margins, ciliate, awned ; iii 

 broadly ovate or -oblong, membranous, 3-nerved, 1-3-awned or 3- 

 cuspidate, usually 2-sexual, palea nearly as broad, 2-cuspidate ; iv 

 smaller, usually male. Lod. cuneiform. Anthers small. Graiia 

 oblong, free. 



1. G. Royleana, Hook f. 



A pretty little grass 3-8" high, with filiform leaves -5-1" long more 

 or less convolute often sparsely ciliate, sheaths rather loose, with 

 scattered long hairs with minute tubercle-bases. Clusters -IS-'S" 

 long (exc. the awns), 1-6 rather remote on the flexuous rhachis. Gl. i 

 (with its awn) -3" long, densely ciliate on to the awn ; iii elliptic- 

 oblong, 3-cuspidate or 1 -awned and 2-cuspidate, -2" long with the 

 cusps, palea narrower, 2-cuspidate, as long ; iv on a short extension 

 of the rhachilla, and its palea -1" long, both shortly awned. Rhachilla 

 produced above iv for -05—06" and bearing 2 short empty awnless 

 glumes. Grain -06" long.

19. TRIPOGON, Roth. 



Slender densely tufted grasses with usually convolute leaves. 

 Spikelets 2 -seriate and unilateral on a very slender terminal spike, 

 not jointed at the base, bearing several flowering glumes and 1-2 

 terminal imperfect ; rhachilla produced between the glumes and 

 jointed at the base and below each glume. Gl. i and ii unequal, 

 1 -nerved, empty, persistent, i usually appressed to the rhachis or 

 lodged in a furrow in the rhachis, often toothed or lobed on one side ; 

 ii entire or notched below the mucronate or subaristulate tip ; iii 

 and other flowering glumes dorsally convex, 2-fid and awned from 

 the keel or 4-fid with the outer lobes awned, the inner membranous 

 and rarely awned ; palea complicate. Lod. 2. St. 2-3. Styles 

 very short. Grain narrow, free.
