274 CLXXIII. GRAMINEJ;. (J. D. Hooker.) [Deschampsia. 



spikelets very shortly pedicelled imbricating brownish-yellow, gls. Ill and 

 IV broad more or le^s 2-lobed lobes irregularly toothed. 



KASHMIR and BALTISTAN, DRAS, and ISKARDO, alt. 10-14,500 ft., Clarke 

 Duthie. DISTRIB. Turkestan. 



Stem 6-18 in., leafy below, rather stout, strict, erect. Leaves 2-5 by -p^-i in., 

 linear, acute, flat, nearly smooth ; ligule oblong. Panicle 1-1 in., erect. Spikelets 

 A-i in. ; gl. I snorter than II, sometimes 2-lobed nearly ^ way down with erose 

 lobes, at others hardly lobed but unequally rather deeply toothed. Perhaps only a 

 form of D. ccespitosa, the fig. glumes of which vary much in breadth and toothing. 

 Hegel describes the leaves of kceleriodes as narrow setaceous and scabrid above, 

 which is totally at variance with his specimens, which are even broader than those of 

 the Indian plant. 



81*. HOLOUS, Linn. 



Annual or perennial tomentose grasses. Leaves usually flat. Spikelets 

 panicled, laterally compressed, oblong, 2-fld. (both fl. bisexual, or upper 

 male or neuter), not jointed on their pedicels ; rachilla articulate at the 

 base produced into a short stipes beyond gl. IV, Glumes 4; I and II 

 empty, persistent, obtuse or acute, keeled, I 1-nerved ; II 3-nerved ; III 

 and IV shorter than I and II, membranous; III not awned, at length 

 hardened ; IV with a slender dorsal awn ; palea narrow, 2-keeled. Lodicules 

 2, cuneiform. Stamens 3. Styles very short, distinct. Grain oblong, free 

 within the hardened gl. Species about 8, European and African. 



H. LANATUS, Linn. Sp. PI. 1047; perennial, softly tomentose, panicle 

 spreading pale green, spikelets in., awn of gl. IV hardly exserted. Fl. 

 Dan. t. 1181 ; Host Gram. Austr. i. p. 275, t. 2 ; Engl. Sot. t. 1169 ; Enapp 

 Gram. Britt. 1. 17 ; Kunth Enum. PI. i. 34, Suppl. 24, t. 9, f. 2 ; Ledeb. Fl.

SIKKIM HIMALAYA ; Darjeeling, alt. 7000 ft., Clarke, apparently naturalized. 

 DISTRIB. Europe, temp. Asia. 



Stems 1-3 ft., densely tufted, roots fibrous, nodes villous. Leaves 610 in. ; 

 upper sheaths inflated; ligule short, oblong. Panicle 2-5 in., branches 2-3-nate. 

 Spikelets pale green or reddish ; gl. I and II acute or apiculate, strongly-nerved ; 

 II often retuse and mucronulate ; III smooth and shining in fruit. H. moilis, L., 

 an almost equally common European grass, may be expected to be introduced into 

 the hills of India; it closely resembles H. lanatus, but has a creeping rootstock and 

 the awn of gl. IV is longer and exserted. 



82. A VENA, Linn. 

 (Including TBJSETUM, Beauv.) 



Annual or perennial grasses. Leaves usually flat. Spikelets 2- or 

 more-fid., in effuse contracted or spiciform panicles, not jointed on their 

 pedicels; rachilla jointed at the base and sometimes between the flg. 

 glumes. Glumes dorsally rounded, I and II empty, subequal or unequal, 

 thin, persistent, few- or many-nerved; fl. gls. ovate or lanceolate, entire 

 2-toothed or -cleft, lobes awned or not, 3-7-nerved, lateral nerves sometimes 

 obsolete ; awn dorsal below the cleft, usually long and geniculate or 

 reflexed with a twisted base, rarely straight; palea narrow, keels scabrid 

 or ciliate. Lodicules usually 2-fid. Ovary glabrous or top villous ; styles 

 short, free. Crrai^yarious, free or (in some sp. with villous top) adherent 

 to the palea. Species many, chiefly N. temperate.
