. WESTERN PAN JAB and MOOLTAN, Aitchison, Stewart, Edgeworth, &c. WESTERN 

 TIBET, alt. 3-7600 ft., Clarke, Duthie, &c. DISTRIB. Affghan., Persia, Turkestan. 



Stem 6-12 in., erect or ascending, slender, puberulous. Leaves 2-8 in., narrow, 

 flat or convolute and filiform ; sheaths smooth, or lower tomentose ; ligule a pubescent 

 ridge. Panicle 2-5 in., cylindric, silvery-yellow, with sometimes purple awns ; 

 racbis pubescent. Spikelets including the awns, in. Ols, I and II narrowly 

 lanceolate, finely pubescent; II rather the longest; III very short, villous, awns 

 softly silky below the middle, the longer four times as long as the gl and about % 

 longer than the intermediate ; palea as in P. elegans. f am doubtful about the 

 identification of Edgeworth's Mooltan plant, of which the only specimens I have seen 

 are very bad, consisting of tall very slender much branched rigid stems 12-18 in. 

 high, with long very narrow rigid leaves, and a spiciform slender flowerless panicle 

 6 in. long, together with a spike of very immature spikelets. It is ticketed as from 

 the Shah Kot Hills.

 shortest. Steud. Syn. Gram. 200 ; Boiss. FL Orient, v. 558. ? P. arabicum,

 Arabia, N. Africa. 



I am very doubtful about this plant, King's specimens of which resemble a 

 small state of P. Aucheri, with much shorter awns, the four shorter of which are nofc 

 so short as in the figure cited of P. brachustachyum. Edgeworth's specimens of 

 P. arabicum and P. nanum are insufficient for identification. 



4. P. robustum, Hook.f. ; stem stout, gls. I and II 3-nerved, awns 

 of III nearly equal, about twice as long as their gls. 



UPPER GANGETIC PLAIN ; Hissar, Drummond (Herb. Duthie). 



Stem 18 in.-3 ft., erect, or geniculately ascending, as thick as a crow-quill, 

 pubescent ; nodes tomentose. Leaves 6-10 by | iu., flat ; lower sheaths pubescent ; 

 ligule a ridge of hairs. JPanicle 2-5 in., silvery-grey, dense-fid., cylindric. Spikelets 

 sessile, in. with the awns, villous ; gl. I shorter than II, ovate-lanceolate ; II 

 lanceolate ; III and palea as in P. elegant, Lut awns shorter, and as in that species 

 with long cilia below the middle. 



96. ARUNDO, Linn. 



Tall stout perennial grasses. Leaves flat, Spikelets few-fld. in large 

 decompound panicles, laterally compressed, fls. mostly bisexual ; rachilla 

 jointed at the base and between the flg. gls., glabrous or shortly hairy. 

 'Glumes 6 or more, I and II subequal, empty, narrow, acute or acuminate, 

 glabrous, scarious, persistent, 3-nerved ; flg. gls. lanceolate, acuminate, or 

 2-fid with a short awn, 3-nerved, dorsally hairy all over below the middle; 

 palea hyaline, 2-nerved. Lodicules 2, obovate. Stamens 3. Ovary glabrous, 

 styles distinct, stigmas plumose. Grain oblong. Species 6 or 7, temp, 

 and trop. 



A. Donax 9 Linn. Sp. PL 81 ; stem creeping below, leaf-base am- 

 plexicaul, panicle erect thyrsiform, spikelets 3-4-fld., gls. I and II obkmg- 

 lanceolate 3-nerved, tip of tig. gls. minutely 2-toothed shortly awned.
