Ischamum.'] CLXXIII. GRAMINEJE. (J. D. Hooker.) 137 



RAJPOOTANA and the CENTRAL PROVINCES, Duthie. The DECCAN, Heyne, &c. 

 BURMA, Wallich, &c. CEYLON, Thwaites. DISTRIB. eastwd. to Australia, and 

 westwd. to the Cape Verd Islds. 



Stems 2-3 ft., tufted on a short stout creeping rootstock, stout or slender, nodes 

 glabrous. Leaves 6-10 in., glaucous, tips filiform, nerves strong; sheath ribbed 

 glabrous or hairy; ligule of silky hairs. Spikes 2-5 in., erect, pale, joints rather 

 coherent; pedicels rather slender, compressed, 2-angled, ciliate, about half as long as 

 the sessile spikelet. Sessile spikelets -\ in., callus shortly bearded; gl. I narrow, 

 nearly flat, nerves very strong especially upwards, those between the lateral irregular 

 in position and length, often anastomosing, margins narrowly incurved ; II elliptic, 

 2-toothed, keel narrowly winged below - the slender awn; III linear-oblong or 

 lanceolate, acute, ciliate, palea as long glabrous 2-nerved ; IV = III, oblong, 

 3-nerved, ciliate ; awn 1^-2 in., column stout ; palea = the gl., linear-lanceolate, 

 2-nerved, ciliate. Pedicelled spikelets ; gl. I ovate-lanceolate, 2-cuspidate, green or 

 purplish, keels narrowly margined, nerves 5-7 very strong scaberulous, lateral pairs 

 close to the margin ; II lanceolate, 3-nerved, acuminate ; IV awnless. 



22. X. sulcatum, Hack. Monogr. Androp. 248; stem simple or 

 branched from the base, leaves linear or lanceolate scaberulous, base 

 rounded or subcordate, gl. I of sessile spikelet narrowly linear -lanceolate 

 glabrous, tip acuminate 3-cuspidate dorsally convex with a narrow deep 

 median channel margins incurved, nerves obscure, II linear-lanceolate 

 2-cuspidate awned, IV 2-fid awned between the lobes. 



The CONCAN, DECCAN and CENTRAL PROVINCES, &c. 



Stems 8-18 in., usually much branched with many solitary terminal spikes, 

 slender, glabrous, nodes glabrous, peduncles very slender. Leaves 2-10 in., glaucous, 

 scaberulous above, setaceously acuminate, strongly nerved ; sheath slender, smooth ; 

 ligule a ciliate membrane. Spikes 2-3 in., strict or curved, green ; joints and pedicels- 

 = | the lower spikelet, slender, ciliate, tips obliquely truncate. Sessile spikelets 

 ^ in. ; callus short, bearded j gl. I scaberulous, tip setiform, keel narrowly margined 

 or winged towards the tip on one side, or simply scaberulous, nerves 2 on each side 

 the furrow; II chartaceous, keel scabrid and margins ciliate above the middle,- awn 

 capillary ; III = f 1, hyaline, acute, paleate, ciliate, palea as long truncate ; IV linear- 

 oblong, 3-nerved; awn f-li in., column stout, brown; palea = the gl. 2-nerved. 

 Pedicelled spikelets smaller than the sessile, neuter, awnless ; gl. I lanceolate, 

 2-cuspidate, 7-nerved, not channelled, margins incurved, keels margined or winged ; 

 II not awned ; III as in the sessile spikelet ; IV acute not awned. Varies greatly in 

 habit from a single ascending stem with one spike to a copiously branched one with 

 many spikes. Hackel describes gl. IV of the sessile spikelet as narrowed into the 

 awn, not 2-fid as I find it. 



23. I. ramosissimum, Hack. Monogr. Androp. 249; stem erect 

 excessively paniculately branched, spikes short in leafy panicles glabrescent, 

 gl. I of sessile spikelet linear-oblong very obtuse emarginate 8-10-nerved 

 deeply channelled between the median nerves margins involute not keeled 

 aculeolately ciliate above, II obtuse mucronulate 5-nerved keel scabrid 

 above with a pencil of hairs, III linear obtuse 3-nerved ciliate paleate, 

 IV = II narrowly linear 1-nerved glabrous narrowed into a stout awn. 



E. INDIES ? Huegel. 



Stem 3-4 ft. Leaves linear-lanceolate, glaucous, glabrous, margins scabrid j 

 ligule chartaceous, truncate. Spikes 1-1 in., straw-colrd., joints linear, compressed, 

 shortly rigidly ciliate, tips excised. Sessile spikelets $ in. Pedicelled spikelets 

 -$ in., linear-lanceolate; gl. I flat acuminate many-nerved; II linear, obtuse, 

 5-nerved ; IV awnless. The two lowest pair of spikelets are imperfect and awnless. 

 I know nothing of this plant.
