200 CLXXIII. GRAMINE^. (J. D. Hooker.) [Andropoyon.

 Nov. Act. Nat. Cur. xix. Suppl. i. (1843) 183. 



Throughout INDIA, BURMA, and CEYLON to the Straits of Malacca, ascending 

 the Himalaya to 5000 ft. DISTRIB. Mediterranean region and tropics generally. 



Stems 1-5 ft., erect or decumbent below, densely tufted, simple or fastigiately 

 branched, compressed towards the base. Leaves 6-18 in., narrow, glabrous or hairy 

 especially near the base, rather glaucous, rigid, margins and upper surfaces scabrid ; 

 sheaths compressed, keeled. Spikes with the lower 2-6 pairs of spikelets male with 

 coherent joints ; joints of upper (fern.) portion very short and curved callus bearded 

 with brown hairs. Sessile (fern.) spikelets ^ in. j gl. I coriaceous, glabrous or hispid, 

 many -nerved, tip membranous; II coriaceous, 3-nerved; III oblong, hyaline, em- 

 bracing the long slender ovary, tip ciliate ; IV awn stout, column hirsute. Pedicelled 

 jpikelets \-\ in. j pedicel very short j gl. I lanceolate, obliquely twisted, herbaceous, 

 keels margined or unequally winged ; II membranous, acute, 3-nerved, ciliate j palea 

 minute, ciliate. Sessile spikelets of the homogamous pairs, like the pedicelled, more 

 or less covered with tubercle-based hairs. Hackel has 2 varieties and 5 subvarieties 

 (excluding polystachyus) of this widely distributed plant, founded chiefly on the 

 number and position of the tubercle-based bristles of the male spikelet. They appear 

 to me to be too inconstant for definition.

 lower 1-3 pairs of spikelets male or neuter with coherent glabrous joints, upper 

 pairs with fragile bearded joints. Sessile (fern, or bisexual) spikelets f-| in., callus 

 long bearded ; gl. I obscurely 9nerved, not furrowed dorsally, margins smooth in- 

 volute ; II coriaceous, linear-oblong 3-nerved, keel hispid ; HI shorter, oblong, nerve-
