792. E. bicolor Roxb. h.f.b.i., iv. 96. Roxb. 133. 
Vern. : — Bard-charayatah III.) 
Habitat : — Dekkan Peninsula, frequent from the Konkan and 
Orissa to Courtallam. 
Erect, annual herbs. Stems muon branched above, slender, 
glandular. Leaves on very short petioles, l^-2in., 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, T ^in., not tapering, capsule globose 
(Trimen). In the Flora of British India, (Vol. iv. p. 96), Mr. (' 
B. Clarke describes it thus : — 
Stem quadrangular, leaves sessile, ovate-lanceolate, 5-nerved. 
Calyx-lobes ovate, suddenly caudate, keel winged, anthers i-£in. 
curved. C. B. Clarke further remarks that E. bicolor is con- 
sidered by Mr. Bentbam only a form of E. tetragonum Roxb. 
but differs from that and the larger E. Perrotteta in the unsym- 
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 1 The plant possesses tonic and stomachic properties, 
and may well be substituted for gentian (Ph. Ind.).
