1G6 STUDIES IN INDIAN TOBACCOS. 



T^jpc XLVI. Plants somewliat early; height 126 ems.; 

 internodes short ; leaves very large, none borne on the ground. 

 Leaves sessile, insertedatan angle of 45° to 60°, becoming horizontal 

 or even bending downwards later, auriculate, amplexicaul, very 

 decurrent (sometimes as much as 5 cms.), the decurrent portion 

 of the lamina being broad ; shape elliptical, the lamina decidedly 

 narrowed in the basal fourth of the leaf; secondary veins arise 

 at an angle of 60° ; apex acute ; margin with very slight 

 undulations ; surface flat ; colour light green ; texture thin ; 

 average length 52 cms. ; ratio length/breadth 2 6. Inflorescence 

 leaves like the lower leaves but smaller. Inflorescence incon- 

 spicuous, not much raised ; side branches not very numerous. 

 Flowers a very pale pink colour which rapidly fades to white ; 

 length about 44 mm. Calyx tubular and inflated, about half the 

 length of the corolla ; teeth moderately long and acute. Corolla 

 with a broad tube ; orifice of the corolla 9 mm. in diameter, 

 the transition between the tube and the dilated portion gradual ; 

 limb entire, but with deep indentations between the lobes which 

 bear short apical points. Capsvle slightl}' longer than the persis- 

 tent catyx, large, broad at the base, but tapering towards the 

 apex which is blunt. 



The anthers are at about the same level as the stigfma and 

 burst in the bud. In the fully open flower the anthers and 

 stigma occupy the same relative positions and are level with the 

 orifice of the corolla.
