13S CLXxiii. GRAMiNE^. (J. D. Hooker.) [Isehcemim. 



24 Z. spathiflorum, Hook. f. ; tall, stout, much branched ahove, 

 spikes enclosed in long narrow spathes very slender, joints and perlice's 

 long, sessile spikelets ^ in. narrowly linear-lanceolate, gl. I of sessile spikelet 

 dorsally deeply channelled densely silkily villous to above the middle, keels 

 rounded scabrid above, II truncate and mucronulate, IV linear-oblonp, 

 awQ slender inserted between 2 subulate teeth. Trachypogon fascioulatus, 

 Munro m-ss. 



Bombay ; hills of Salsette Isld. in stony places, Jacquemont (n. 797). 



Stem 3-4 ft., as thick as a goose-quill below, leafy above, branches erect, nodes 

 glabrous. Leames 12-18 by f in., finely acuminate, carrowed from the middle to the 

 base, almost petioled, thin, sparsely hairy above and beneath, margins smooth, midrib 

 stout pale, nerves obscure; sheath of lower 6 in. and upwards, terete, quite glabrous, 

 of upper passing into compressed lanceolate flg, spathes 3-4 in. long, which alternate 

 In very slender axillary hranchlets, the lower with leafy tips ; ligule short, scarions. 

 Spikes about 2 in. long, more or less exserted from the spathes, very slender, pale 

 straw-colrd. j joints and pedicels more than half as long as the sessile spikelet, 

 compressed, one angle ciliate. Gl. I of sessile spikelet white with silky hairs, thiuly 

 coriaceous, nerveless, dorsal channel slender transparent forming a ridge ventrally, 

 margins equally involute from base to 2-fid or truncate 2-cuspidate tip ; callus very 

 short, bearded ; II chartaceous, dorsally convex, nerveless but with a nerve-like 

 fold towards the ciliate margin, keel with long cilia above the middle, scabrid towards 

 the emarginate tip ; III shorter, hyaline, oblong-lanceolate, obtuse, '3-nerved, margin 

 above with reflexed hairs ; palea lanceolate, 2-nerved, anthers imperfect ; IV as long 

 as III, linear, 3-aerved; awn 1^ in., yellow, rather testaceous, palea 0. Pedicellei 

 spikelets longer, J in. ; gl. I dorsally convex (not sulcate), shortly silky, narroweil 

 into a long bisetose glabrous awn. — A very curious species, of which the materials 

 are in rather a young state j it should form a section by itself of Sehima were that 

 genus to be restored. 



25. X. notatum, Hack. Monogr. Androp. 246 ; stems tall tufted, leaves 

 linear narrowed from the base upwards, rigid sabstrigose, spikes rather 

 stout fragile, gl. I of sessile spikelets oblong, gl. I ovate-oblong glabrous, 

 tip membranous 2-cDspidate dorsally flat with 2 carinal nerves and 2-3 

 intermediate short green anastomosing ones, keels margined or winged, 

 II 3-nerved shortly awned, IV shorter oblong 2-fld ciliate awned in the 

 cleft. 



Westeen Himalaya, alt. 4-7000 ft., from Chamha, Thomson, to Kumaon, 

 Strachey ^ Winterhottom. 



Stem erect, naked or pubescent below the spike, nodes glabrous. Leaves 6-10 

 by i-i in., setaceously acuminate, green or hoary ; sheath bearded at the tip ; ligule 

 of long hairs. Spikes 3-8 in., strict or curved, fragile, pnberulous ; joints and 

 pedicels snbclavate, half as long as the sessile spikelet, villously ciliate, tips obliquely 

 truncate. Sessile spikelets i in., callus short bearded ; gl. I obliquely ovate-oblnii);, 

 tip membranous, margins very narrowly inflexed, keels one or both narrowly winged ; 



II chartaceous, entire, 3-nerved, keeled and narrowly winged in the upper third ; 



III oblong, obtuse, ciliate, 2-nerved, palea 2-nerved eciliate; IV 3-nerved, awn 

 f-1 in. ; palea linear-lanceolate. Fedicelled, spikelet, gl. I lanceolate, acuminate, 

 a-cuspidate, 7-9-nerved; II lanceolate, acute, glabrous; III as in the sessile; IV 

 awnless. 



Sect. III. Spikes few or many, subracemose. Gl. I of sessile spikelet 

 deeply or obscurely channelled along the mesian line. 



26. X. petiolare, Hac^. Monogr. Androp. 238 ; tall, stout, leaves long 

 narrowed at the base or petioled, spikes many subpaniculately fascicled, 

 gl. I linear-oblong keels narrowly winged towards the 2-toothed truncate 

 tip dorsally deeply channelled, II cymbiform acuminate or muoronate, IV
