138 CLXXIII. GRAMINE^E. (J. D. Hooker.) [Ischcemum. 



24. I. spathiflorum, Hook, f. ; tall, stout, much branched above, 

 spikes enclosed in long narrow spathes very slender, joints and pedicels 

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

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

 rounded scabrid above, II truncate and mucronulate, IY linear-oblong, 

 awn slender inserted between 2 subulate teeth. Trachypogon f asciculatus, 

 Munro mss. 



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. Leaves 12-18 by f in., finely acuminate, narrowed 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 branchlets, the lower with leafy tips ; ligule short, scarious. 

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

 straw-colrd. ; 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, thinly 

 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 j 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-nerved ; awn 1| in., yellow, rather testaceous, palea 0. Pedicelled 

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

 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. I. 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-cuspidate 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-fid ciliate awned in the 

 cleft. 



WESTEEN HIMALAYA, alt. 4-7000 ft., from Chamba, Thomson, to Kumaon, 

 Strachey fy Winterbottom. 



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

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

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

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

 truncate. Sessile spikelets in., callus short bearded ; gl. I obliquely ovate-oblong, 

 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. Pedicelled spikelet, gl. I lanceolate, acuminate, 

 2-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. I. petiolare, Hack. 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 mucronate, IV
