170 CLXXiii. GRAMiNEiE. (J. D. Booker.) 



awn 1 ill. slender j palea small, linear-oblong, ciliate. Pedicelled tpikelets narrower 

 and rather smaller than the sessile, purplish; gl. I ovate-lanceolate, 2-caspidate, 

 keels long ciliate above the middle; II and III as in the sessile spikelet. — According 

 to Hackel the Indian plant dififers from the African in the longer hairs of the joints 

 and pedicels and in the more exserted peduncle of the spikes, but I find that these 

 and other minute characters are very inconstant. Homceatherum chinense, j¥ee», 

 included under A. apricus, is, I think, certainly A. fasiigiatus. 



11. A. long'ipes, Sack, in Flora (1885) 138 ; annual, stem slender 

 ascending, leaves linear and sheaths sparsely hirsute, spikes 2 both stipitate, 

 peduncle naked (spathe 0), joints many and pedicels rather stout subclavate 

 tips cupped shortly ciliate, sessile spikelets -^ in. dorsally _ compressed 

 oblong-lanceolate, gl. I broadly unequally winged above the middle aristn- 

 late, II long-avmed, IV obovate cleft to the middle, awned between the 

 lobes.

Stems 12-16 in., decumbent below, nodes glabrous. Leaves 4-6 by J-J id., 

 hairs tubercle-based; ligule very short. Spikes 2-3 in., rather stout, dense- 

 fld., green ; joints and pedicels = i the sessile spikelet, concavo-convex, margins 

 rounded. Spikelets imbricating, callus short, obtuse, bearded ; gl. I dorsally sparsely 

 hairy and depressed or convex, many-nerved, wing produced beyond the sainmit 

 serrulate; II ciliate, 3 -nerved, lateral nerves submarginal, tip 2-toothed, ketl 

 scaberulous, awn as long as the gl. ; III hyaline, 2-nerved, copiously ciliate ; IV as 

 long as III ; lobes lanceolate, acuminate; awn J in., glabrous. Pedicelled- spikehU 

 as long as the sessile, male; gl. I shorily awntd, 6-7-nerved; II membranous, 3- 

 nerved ; III and IV linear-oblong, ciliate. — -I have seen only one specimen. This, 

 I think, is a doubtful member of the subgenus, the peduncle not arising from a distinct 

 flattened spathe.

12. A. pumilus, Moxb. Fl. Ind. i. 273 ; stem panicnlately branched, 

 leaves narrow, spikes in pairs, joints and pedicels clavate or trnmpet- 

 shaped, sessile spikelets dorsally compressed, gl. I very narrow lanceolate 

 deeply channelled between the thickened keels, IV very narrow bisetose.

Annual or perennial ? Stem 6-18 in. high, slender, suberect or geniculate and 

 decumbent below ; nodes glabrous. Leaves 3-5 in., rarely i in. broad, sometimes 

 almost filiform, acumiuate, glabrous ; sheath compressed, keeled ; ligule short, 

 truncate. Spikes i— | in., in pairs terminating a very slender peduncle which arises 

 from a narrow flattened glabrous spathe i-i in. long ; joints 6-8 and pedicels shortly 

 ciliate on one margin, tops dilated cupped with 2-3- toothed margins. Sessile 

 spikelets ^ in. ; callus glabrous ; gl. I membranous, acuminate, bicuspidate, lateral 

 ribs often ending below in 2 tubercles ; II as long, narrowly lanceolate, mucronate, 

 coriaceous ; III shorter, linear, hyaline, 2-nerved ; IV very narrow, cleft into two 

 capillary -lobes with an interposed capillary awn -^— ^ in. long; palea minute, 

 oblong. Fedicelled spikelets i~^ in., ovate-lanceolate, acuminate, 5-nerved; gls. 3. 

 — An excellent figure amongst Roxburgh's drawings attests Hackel's A. pachg- 

 arthrus being A. pumilus. The peduncle of the spike is sometimes 2 in. long. 

 Wallich's n. 8799 is very tall and slender, as if drawn up amongst other plants.
