with by grazing, grass-cutting, or other agency, those plants with the more 

 hairy glume II are usually less robust and less coarse, or rank, than the others, 

 and they are therefore as a rule most valued for fodder and are distinguished 

 locally by the vernacular name of dhaula, whereas the coarser plants with 

 smooth glume are called gurla. As this grass affords a valuable fodder and is 

 sometimes cultivated, in consequence, it is important to determine the extent to 

 which its characteristics are constant. If, as suggested above, they depend on 

 the available moisture, it is obvious that cultivation of this grass on good 

 agricultural land, with a large quantity of available moisture, would result in 

 producing an inferior class of rank, coarse fodder.'

 polyphyllus, Hook. f. in F. B, I. vii, 194 {qui habet Hack. mss. in Herb. 

 Duthie).— A. Aucheri, var. polyphyllus, Hack, in Herb. Duthie. 



Description : Stem 60-90 cm, high, as thick as a crow-quill or more, stiff, 

 simple or fastigiately branched, quite glabrous. Leaves crowded or not, 15-25 

 cm. by 2-4 mm., narrow, rigid, acuminate, flat, pale glaucous-green, glabrous 

 on both surfaces, coriaceous, midrib and nerves very slender, margins minutely 

 scaberulous ; sheaths terete, appressed, hard. Panicle 10-13 cm. long, oblong, 

 subsecund, dense-flowered, very pale, branches 6-12 mm., very unequal, in many 

 closely approximate whorls, smooth, peduncle slender, quite glabrous. 

 Sessile spikelets 4 mm. long, drooping, white or pale purplish, callus long, 

 li mm. long, obtuse, bearded at the very base only with long fulvous hairs. 

 Glumes as in C. montanus . Lower involucral glume obtuse, glabrous, keel 

 ciliate towards the tip ; upper not awned, keel glabrous or ciliate. Upper 

 floral glume with an awn 3-8 mm. long, nearly straight, pale. Pedicelled spike- 

 lets narrowly lanceolate, acuminate, glabrous, 7-nerved, eciliate, not awned, 

 rather longer than the sessile ; pedicels naked, villous at the tip only. 



Can easily be distinguished from C. montanus by the stout naked callus 

 which is bearded at the base only, and by the naked pedicels which are long- 

 villous only at the tip. 



It differs from the next species, C. Aucheri by its size, the long, glabrous 

 glaucous leaves and the glabrous peduncle and branches of the panicle.

Description : Cke. 1. c. 



Stapf thinks that C. Aucheri comprises several geographical races and that 

 the one from which the species was first described extends from Arabia through 

 Southern Persia and Baluchistan to Sind. He characterizes it ' by the lower 

 glume of the pedicelled spikelet being usually awnless or in any case much 

 more shortly awned than the upper, by the glume awns not being ciliate or 

 ciliate only at the base, and by the longer beards of the pedicels.' 



Locality: Sind: Gizri (Sabnis B777 !) ; Jemadar ka Landa near Karachi

Distribution: Sind, Baluchistan, Afghanistan, S. Persia, Arabia (not 

 Africa). 



30. Arthraxon Beauv. Agrost. Ill ; Cke. ii, 967. 



Species about 20, in the tropical and subtropical regions of the Old World. 



We retain the 6 species mentioned by Cke. I.e. His A. lanceolatus, 

 Hochst. will be slightly restricted under the name of A. serrulatus, Hochst., the 

 name A. lancifolius , Hochst, will be substituted for A. microphillus, Hochst., 

 and A. quartinianus, Nash, will take the place of A. ciliaris, Beauv.
