282 CLXXIII, GRAMINE^. (J. D. Hooker.) [Dantlwnia. 



the tip, variable in length, about twice that of gl. II ; callus bearded ; palea as long 

 as the gl., linear, obtuse, keels nearly smooth. Anthers linear. Grain narrowly 

 oblong, glabrous, A very variable plant in panicle but constant in habit. Jaubert 

 and Spach's figure is of a very starved small form, and I have not found in Jacque- 

 mont or other specimens the whorl of hairs at the top of the pedicel (base of gl. I 

 and II) which they represent. The nervation of gl. I and II varies remarkably. I 

 find both 3-nerved in Sikkim specimens, both 5-nerved in many Western Himalayan ; 

 both sub 7-nerved in Kunawur ones ; both 4-nerved in Simla ones ; I 3-uerved, II 

 5-nerved in some Western ; I 5-nerved, II 7-nerved in Gajwhal ; I 5-nerved and II 

 sub 6-nerved in Jacquemont's n. 260, in which the awn is twisted to the tip ; both 

 are very sparsely hairy in a few specimens. The lower sheaths are villous in Simla 

 (Hattu) specimens. 



Var. minor', stems 6-8 in. very slender, leaves filiform, panicle often recurved, 

 spikelets 4-8, gl. 1 and II often purple 5-7-nerved. Danthonia No. 2. Herb.

4. D. Cumminsii, HooJc. f. ; stem ascending, leaves filiform, panicle 

 small, rachis and pedicels villous, spikelets 3-6 i in. long very shortly 

 pedicelled, lateral awns of gl. Ill very short, median not twice as long as 

 gl. II hardly twisted.

Possibly a form of D. cachemyriana, but the characters are marked. The 

 specimens are curved in a semi-circle, no doubt from growing amongst rocks, as 

 was the case with Calamagrostis tripilifera, var. (p. 262). 



DOUBTFUL SPECIES OF DANTHONIA. 



D. GRTFFITHIANA, C. Muell. in Bot. Zeit. xiv. (1856) 374. Khasia Hills,

 idea of what it may be.

 No. 123 in Clavis, p. 8. 



Tufted perennial erect glabrous grasses. Leaves linear, subconvolute. 

 Spikelets 3-5-fld., often bracteate, in a short simple unilateral raceme, later- 

 ally subcompressed, not jointed on the pedicels, uppermost fl. imperfect ; 

 rachilla articulate. Gls. I and II empty, persistent, lanceolate, acuminate, 

 7-11-nerved, dorsally rounded; fl. gls. herbaceous, oblanceolate, 7-11-nerved, 

 2-fid, awned in the sinus, margins membranous, awn half-twisted ; palea 

 2-keeled, keels scabrid, excurrent. Lodicules 0. Stamens 3. Ovary hispid, 

 narrowed into a slender style ; stigmas very long, papillose, exserted from 

 the top of the spikelets. Grain oblong, crowned with the style, hirsute. 

 Species 2, Western Himalaya and Affghanistan.
