 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 J^j-J in., linear, setaceously acuminate, scaberulous or smooth, 

 marg'ms scabrid; sbeatU 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, glabrous 

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

 hairs, Spil<es i-| in., one subscssile with one pair of homo;?amous spikelets, the 

 other ^-l in. long with two (rarely 0) homogamons pairs ; heterogamous spikelets 

 1-3 pairs ; joints and pedicels very short, linear, ciliate or villous, tips very oblique. 

 QL I of sessile spikelets |-^ 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. 

 Pedicelled spikelets linear-lanceolate, gl. I acute, 7-9-nerved, keels setulose;!^ 

 oblong, keeled; III and IV hyaline or 0. — Homogamons spikelets not awned.-- 

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

 of the spathe and peduncle, and the number 1 or 2 of the heterogamous spikele^ 

 Of these % TMvaitesii is the Ceylon plant, with one pair of heterogamous and t^o w 

 homogamons on the stipitate spike. A. finifimus has normally 2-3 pairs of heteroga- 

 mous spikelets on each spike. — These and two other African species, ^. ^^ S\ 

 Hack., and -4. famlliaris, Steud., are very closely allied, and regarded by Hacke 

 as probably subspecies oi fiUpendulus,
