Stem 2-3 ft., stifiF, as thick as a crow-quill or more. Leaves crowded, or i?ot 

 6-10 by Jj-i in., pale glaucous-green and smootli on both surfaces, midrib and' 

 nerves very _ slender, margins minutely seaberulous ; sheaths appressed, hard. 

 Panicle 4,-5 ia.; branches J-J in., very unequal; peduncle slender, quite glabrous'. 

 Spikes drooping, white or pale purplish. Glumes as in ^. monticola. Pedicelled, 



sfihelets rather longer than the sessile ; pedicels = about i ? the sessile spikelets. 



Habit, foliage and secund panicle very unlike jt. monticola, and remarkable for the 

 Btont naked callus about Jj in. long with a long-bearded base, and the naked 

 pedicels villous at the tip only with erect fulvous hairs half as long as the spikelets. 

 It differs from Aucheri, in the tall habit, long-glabrous glaucous foliage, glabrous 

 peduncle and branches of the panicle, callus, pedicels, awnless pedicelled spikelets, 

 and the very short awn of gl. IV of the sessile spikelet.

Stem 6-18 in., simple or sparingly branched, base thickened, leafy. Leaves 2-4 

 by -^g-^ in., sometimes undulate, acute or acuminate, pale green, often ciliate 

 tawards the base, margins seaberulous ; sheath very pale. Panicle 2-3 in., erect, 

 iong-peduncled, raehis scabrid. Spilces usually crowded, rarely binate on a branch. 

 Sessile apilielets ; callus obtuse ; gl. I compressed, with sometimes long terminal 

 bristles f II awned or not, awn hirsutely ciliate ; III and IV as in A. monticola. 

 Fedicelled. spikelets -i^J in., pedicels silkily villous from base to apex ; gl. I sparsely 

 ciliate. jofaaUy, and with very long cilia on the keels towards the tip, awn pale 

 iirsute. — I have confined the description to the Seind plants. Hackel describes the 

 sptcies, which extends to Persia, Arabia, Morocco, and S. Africa as extraordinarily 

 variable, no two specimens agreeing in sU points, and the spikelets varying in the 

 same specimen.' These remarks would probably apply to all the allied species of 

 Ckjsopogon, in whose stability I have no confidence.
