truncate tip. Steud. 8yn. Gram. 392 ; Hack. Monogr. AnArop. 541. A. 

 gangeticus, Sack. I. c. 539. — Andropogon, Wall. Cat. n. 8816. 



Teopioal Himalaya, from Garwhal to Sikkim. Lowbe Benbal, Assam, the 

 CentbaIi Pbotinoes, and BubmA. — Distkib. Tonkin. 



Stem 2-3 ft., decumbent and branched below, leafy, nodes glabrous or nearly so. 

 Leaves 12-16 by i-J in., glabrous or hairy, base narrowed, setaceously acuminate, 

 scaberulons ; sheath hirsute or subglabrons, mouth bearded j ligule shortly ovate. 

 Panicle 1-2 in., long-peduncled, usually narrow, green or purplish ; rachis slender, 

 glabrous or nodes bearded ; branches erect, lower usually binate covered to the base 

 with spikes. Spikes J-J in. ; joints few, flattened but not 2-ribbed, clliate with 

 white or purple hairs. Sessile spileelete dorsally flattened, callus bearded j gls. thin, 

 I glabrous on back and sides, margins involute, nerves very slender; II charta- 

 ceous, acute, 5-7-nerved ; III lanceolate, 2-uerred, ciliate ; IV much shorter, 2-fid, 

 lobes triangular, ciliate ; awn J in. long ; palea 0, or minute, broadly ovate. Otary 

 glabrous. Pedicelled spileelete neuter, narrower than the sessile ; gl. I many-nerved, 

 keels scaberulons ; II acute, 7-nerved ; III obovate-oblong, ciliate. — A good character 

 of this species is the branches of the panicle bearing spikelets down close to the 

 rachis. Hackel (who doubtfully places this in his subgenus Sorghum) describes gl. 

 IV of the sessile spikelet as having a lanceolate acuminate glabrous nerveless palea 

 as long as the gl. ; no doubt an error. 



28. A. venustus, Thw. Unum. PI. Zeyl. 367 ; stems tall, leaves 

 narrow, sheaths hardly compressed, panicle elongate interrupted, rachis 

 and spreading opposite and alternate branches capillary glabrous, spikes 

 small, joints 3-8 and pedicels very slender glabrous terete not chan- 

 nelled, sessile spikelets narrowly lanceolate acute, gl. I dorsally com- 

 pressed nerveless tip 2-toothed, keels scabrid above the middle, II very 

 shortly awned, keel smooth or scabrid upwards. Hack. Monogr. Androp.

Ceylon ; Central Province, alt. 4000 ft., Thwaites. 



Stem 2-4 ft., strict, subsimple, as thick as a goose-qnill below and clothed with 

 short pubescent sheaths. Leaves 12-16 in., smooth or scaberulons above, midrib 

 very broad and prominent beneath ; sheath subcompressed, smooth ; ligule a ridge 

 of hairs. Panicle 12-16 In., dull purplish, much branched. Spikes narrow, lax- 

 fld., joints 3-8 and pedicels = i the sessile spikelets. Sessile spikelets J in., slightly 

 curved ; callus small, stellately bearded with white hairs ; gl. I quite smooth, flut or 

 rather convex dorsally ; II chartaceous, linear-lanceolate, acuminate, 3-nerved, 

 keel acute ; III smaller, ovate, acuminate or aristulate, ciliate above, 1-3-nerved j 

 IT linear, 2-fid, awn very slender. Pedicelled spikelets longer than the sessile and 

 inore acuminate, nearly glabrous, male ; gl. I 7-nerved, 3 towards the margin on each 

 side; II and III as in the sessile; IV narrow, glabrous, awn 0. — Hackel, who places 

 this in subgen. YeUveria, describes gl. I of the pedicelled spikelet as o-nerved. The 

 habit spikelets and glumes are those of subgen. Amphilophis, but the joints and 

 pedicels are not channelled. Dathie (Grass. N.W. Ind. 22) gives the Jhelum 

 Valley, Stewart, as a habitat, doubtless erroneously. 



B. Spikes small, of 1-3- rarely 4 pairs of spikelets, often reduced to 3 

 spikelets, a sessile and 2 pedicelled. Panicle more or less pyramidal, 

 rachis and branches capillary. 



29. A. mlcrantbus, Kunth Bems. Oram. i. 165, Unum. PI. i. 504; 

 stem erect or ascending simple or nearly so, leaves linear base hardly 

 narrowed sheaths closed, spikes of 2-3 pairs of spikelets, joints and 

 pedicels shortly ciliate or subglabrous, sessile spikelets ^-i in., gl. I 

 Imear-oblong dorsally channelled glabrous scaberulons or villous, keels 

 minutely subpectinately ciliate. Bteud. 8yn. Gram. 396; Sack Monogr.
