Calamagrostis.1 CLXXIII. GKAMINEJI. (J. D. Hooker.) 265 



a slender petiole, canline filiform convolute, panicle short broad, branches 

 few and long pedicels capillary, spikelets few ^- in., gl. I and II unequal 

 lanceolate, III truncate bicuspidate from the outer pair of nerves, awn 

 subbasal exserted, callus hairs short, anthers linear. 



NILGHIRI HILLS ; Ootacamund, Schmid. 



Rootstock as thick as a crow-quill. Stem filiform. Radical leaves 2-3 in., 

 glabrous, nerves strong; petiole very slender stiff; sheaths of old basal leaves 

 clothing the base of the new, lacerate, about an inch long ; ligule long, linear, mem- 

 branous. Panicle broad, rachis and few distant branches quite smooth. Spikelets 

 pale purplish, gl. land II membranous, 1-nerved, keels scaberulous ; III hyaline, 

 5-nerved, hairy, awn twice as long as the spikelet ; palea very minute, suborbicu. 

 lar. 



I have seen only one poor specimen of this curious species, which should at 

 once be recognized by its rootstock, and the slender rigid petioles of the leaves, 

 long ligule, and tufted lacerate old leaf-sheaths about an inch long, crowning the 

 rootstock. There is, however, in Herb. Kew a specimen of what may be the same 

 species collected by Clarke at Conoor (in the Nilghiris) alt. 7000 ft., with a very 

 slender stem 2-3 ft. long, and narrow flat sessile cauline leaves with a short ligule; 

 its spikelets quite accord with those of C. Schmidii, but the base of the stem and 

 lower leaves are wanting. 



12. C. Jacquemontii, Hook. f. ; tall, slender, leaves very narrow, 

 ligule oblong, panicle narrow drooping, branches erect naked below, 

 spikelets few i |- in. long-pedicelled erect, gl. I and II subequal lanceolate 

 sub 3-nerved, III = about II tip truncate 4-toothed, awn supra-basal 

 exserted, palea minute, callus hairs = | gl. Ill, anthers long. 



KASHMIR; moist places on the Pyr Panjal, Jacquemont (n. 97). 



Stems apparently tufted, 18 in. high, geniculate below. Leaves 5-6 by in., 

 scaberulous ; sheaths quite smooth ; ligule oblong. Panicle 4-5 in., lower branches 

 fascicled, 1-1 i n -> scaberulous. Spikelets pale yellowish ; keels of gl. I and II 

 smooth, III hairy all over. I have seen only two specimens. The long spikelets 

 distinguish it. This approaches var. ciliata of C. pilosula, but the spikelets are 

 considerably larger. 



DOUBTFUL SPECIES. 



C. HOOKERIANA, Steud. Syn. Gram. 292. Lachnagrostis Hookeriana, Nees ex 

 Steud. A Ceylon plant described as having the palea as long as its gl. which occurs 

 in no Ceylon specimen of the genus known to me. 



C. ROYLEANA, Steud. Norn. Ed. II. i. 251. C. Roylei, Steud. Syn. Gram. 193. 

 Agrostis Royleana, Trin. in Act. Acad. Petersb. Ser.VL vi. Sc. Nat. II. (1845) 371. 

 Lachnagrostis Royleana, Nees in Herb. Royle ex Steud. Nom. 1. c. L. Hookeri, 

 Nees ex Steud. Syn. 1. c. Trinius founded this species on three plants, an Indian of 

 Royle, a Nilghiri of Zenker, and a Ceylon one from "Herb. Whytt." One of his 

 characters is the presence of a " bearded rudiment," which refers the plant to 

 Deyeuxia. I know of no Deyeuxia in Ceylon or the Nilghiris. 



75. DEYEUXIA, Clar. 



Characters of Oalamagrostis, but with the rachilla of the spikelet pro- 

 duced beyond gl. Ill and usually penicillate with silky hairs ; gl. Ill 

 glabrous; hairs of callus usually short. Species enumerated about 120. 



See remarks under Agrostis (p. 253). In D. Treutlerl the produced portion of 

 the rachilla is most minute and naked, in I>. abnormis it is awnless and the rachilla
