Locality : Jemadar ka Landa near Karachi (Stocks 646). 



89. Enteropogon, Nees ; Hook. f. in F.B.I, vii, 284. 



Tall, slender, perennial grasses. Leaves long, very narrow. Spikelets very 

 narrow, 1-2-flowered (lower flower perfect, upper if present male or neuter) 

 unilateral in a solitary terminal slender spike, not jointed at the base ; rhachilla 

 jointed at the base. Glumes 3 or 4. Lower involucral glumes unequal, 

 narrow, hyaline, 1-nerved, persistent ; lower floral glume much larger, linear, 

 rigid, scabrid, dorsally rounded, 3-nerved, tip entire, or acutely bifid with a 

 short erect awn in the cleft ; callus bearded. Pale lanceolate, 2-toothed, keels 

 scabrid. Lodicules 2. Anthers very long. Styles distinct. Grain narrow, 

 free within the hardened glumes. 



Species 3.— India, Africa. 



1. Enteropogon badamicum, Bhide in Journ. & Proc. As. Soc. Beng. new series, 

 vii (1911), 517. 



Description: Stem 60-75 cm., slender, erect, glabrous. Leaves narrow, 

 10-18 cm. by 3-6 mm., tapering to a fine acumination, glabrous; sheath 

 glabrous, finely long-ciliate at the mouth and sides ; ligule a short membrane 

 with a fine fringe of hairs. Spike solitary, terminal, 15 cm. long. Spikelets 

 2-seriate and secund on a flattened, trigonous, slightly scabrid rhachis, sub- 

 sessile or very shortly pedicelled. Involucral glumes persistent, empty, 

 scarious, 1-nerved, glabrous or very minutely puberulous, the lower less than 

 half of the upper, more or less unequal-sided and sometimes slightly lobed on 

 one side, ovate, subacute and erose at the apex ; upper shortly unequally 

 2-dentate at the apex with a short mucro between. Lower floral glume slightly 

 longer than upper involucral, 2-dentate at the apex, 3-nerved with a dorsal 

 stiff awn about as long as the glume, scabrid at the back and sides, ventrally 

 grooved, the groove corresponding with the dorsal ridge which is continuous 

 with the awn. Callus bearded with short white silky hairs. Pale a little longer 

 than the glume, scabrid at the back and on the keels, 2-nerved, apex slightly 

 bifid and erose, with a bisexual flower. Grain oblong, flattened, as long as the 

 pale. Upper floral glume like lower, but smaller and also bisexual ; rhachilla 

 produced beyond the upper floral glume and bearing a sterile awned glume 

 which is much smaller than the upper floral glume. 



Locality : S. M. Country : Badami (Bhide ! Talbot 2924 !), 



Distribution : So far endemic.
