170 CLXXIII. GRAMINE&. (J. D. Hooker.) [Andrqpogon. 



awn 1 in. slender ; palea small, linear-oblong, ciliate. Pedicelled spikelets narrower 

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

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

 to Hackel the Indian plant differs 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, Nees, 

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



11. A. longripes, Hack, 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 aristu- 

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

 lobes.

Stems 12-16 in., decumbent below, nodes glabrous. Leaves 4-6 by | i in., 

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

 fld., green ; joints and pedicels = 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 summit 

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

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

 long as III ; lobes lanceolate, acuminate; awn f in., glabrous. Pedicelled spikelets 

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

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

 I think, is aj'pubtful member of the subgenus, the peduncle not arising from a distinct 

 flattened spathe.

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

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

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

 deeply channelled between the thickened keels, IY 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 in. broad, sometimes 

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

 truncate. Spikes ^-f in., in pairs terminating a very slender peduncle which arises 

 from a narrow flattened glabrous spathe - j in. long; joints 68 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, mucrouate, 

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

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

 oblong. Pedicelled spikelets %-$ in., ovate-lanceolate, acuminate, 5-nerved; gls. 3. 

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

 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.
