210 OLXxiii. QRAMiNE^. (J. D. Hooket.) [Andropoyon. 



Khasia Hilm, Oriffih, Clarie. Cetlohj BaduUa district, alt. 3000 ft., 

 Thwaites. — Disteib. Trop. Asia, Afr., and Austral. 



Stems 3-4 ft., erect, leafy, subsimple or branching from the base, nodes glabrous. 

 Leaves 2-3 ft. by yg-J in., linear, setaceously acuminate, scaberulous or smooth, 

 margins scabrid ; sheath terete, smooth, glabrous or mouth hairy ; ligule short, mem- 

 branous. Panicle 1-2 ft., narrow, compound, branches slender, nodes glabrous or 

 pubescent. Spathes 1-3 in., linear-lanceolate, acuminate, or tips setaceous, glabroos 

 ciliate or hairy. Peduncle much shorter than the spathe, bearded above with white 

 hairs. Spikes i-f in., one subsessile with one pair of homogamous spikelets, the 

 other j^-| in. long with two (rarely 0) homogamous pairs j heterogamoas spikelets 

 1-B pairs ; joints and pedicels very short, linear, ciliate or villous, tips very oblique. 

 01. I of sessile spikelets J-J in. ; callus acute, bearded ; gl. I membranous, truncate, 

 5-7-nerved, glabrous or villous, dorsally slightly channelled or not ; II oblong, 

 obtuse, keel glabrous or ciliate, 3-nerved; III linear-oblong, obtuse, hyaline, ciliate; 

 IV shorter, 2-toothed, glabrous; awn 2-2^ in., column hispid with rufous hairs, 

 Fedicelled spikelets linear-lanceolate, gl. I acute, 7-9-nerved, keels setulose; II 

 oblong, keeled; III and IT hyaline or 0. — Somogamous spikelets not awned.— 

 Hackel has 4 varieties under A. fiUpendulus, depending chiefly on the relative length 

 of the spathe and peduncle, and the nnmber 1 or 2 of the heterogamous spikelets. 

 Of these y. Thwaitesii is the Ceylon plant, with one pair of heterogamous and two of 

 homogamous on the stipitate spike. A. finitimus has normally 2-3 pairs of heteroga- 

 mous spikelets on each spike. — These and two other African species, A. Barteri, 

 Hack., and A. familiaris, Steud., are very closely allied, and regarded by Hackel 

 as probably subspecies of fiUpendulus.
