792. E. bicolor Roxb. h.f.b.i., iv. 96. Boxb. 133. 



Vern. : — Bara-charayatah (II.)

Erect, annual herbs. Stems much branched above, slender, 

 glandular. Leaves on very short petioles, li-^in., oval, tapering 

 on both ends, acute, 3-(or 5-) nerved. Flowers 4-merous, small, 

 on long rigid pedicels, rather small, pale, violet-blue or white ; 

 Calyx-segments ovate, very acute, wings wide, cordate or sub- 

 cordate at base, strongly veined. Corolla fin. diam., lobes 4, 

 lanceolate, acute ; anthers 4, x^in., not tapering, capsule globose 

 (Trimen). In the Flora of British India, (Vol. iv. p. 96), Mr. C. 

 B. Clarke describes it thus : — 



Stem quadrangular, leaves sessile, ovate-lanceolate, 5-nerved. 

 Calyx-lobes ovate, suddenly caudate, keel winged, anthers i-Jin. 

 curved. C. B. Clarke further remarks that E. bicolor is con- 

 sidered by Mr. Bentbam only a form of E. tetragon um Roxb. 

 but differs from that and the larger E. Perrotteta in the unsy in- 

 metric flowers, the buds distinctly curved at the tips and the 

 anther-cells curved and tapering upwards. The flowers are 

 larger than those of E. tetragonum, smaller than those of E. 

 Perrotteta. The corolla-segments are (very generally) white on 

 the lower half, full azure-blue in the upper. 



Use : — The plant possesses tonic and stomachic properties, 

 and may well be substituted for gentian (Ph. Ind.).
