12G STUDIES IN INDIAN TOBACCOS. 



Type XXIV. Plants very late ; height 149 cms. ; lower 

 internodes very short, causing some of the leaves to lie on or near 

 the ground, upper internodes long ; inflorescence raised on the 

 main axis, with secondary branches at the top only. Leaves 

 sessile, inserted at an angle of 45**, bending over to become more 

 or less horizontal, amplexicaul, slightly auriculate, decurrent for 

 about 2 '5 cms., elliptical, lamina narrowed for a short distance 

 above the base ; secondary veins arise at an angle of 60° or more ; 

 apex acuminate ; margin with slight regular undulations ; surface 

 puckered and raised between the secondary veins ; colour blue- 

 green ; average length 52 cms. ; ratio length/breadth 2*6. 

 Inflorescence leaves similar to the lower leaves but lanceolate and 

 with occasional deep undulations at the base. Inflorescence much 

 raised on the main axis with a few spreading side-branches borne 

 near the apex. Flowers pink ; length 45 mm. Calyx tubular, 

 somewhat inflated, a little less than half the length of the corolla ; 

 teeth long and acute. Corolla with an orifice 8 mm. in diameter, 

 and a broad tube, the transition between the tube and the dilated 

 portion slightly abrupt : limb divided to about half its depth, with 

 small folds at the junctions of the lobes ; lobes much rounded at 

 the base ; apical points short. Capsule slightly shorter than the 

 persistent calyx, cylindrical ; apex pointed. 



The anthers burst as the bud expands when just level with 

 or just above the stigma. In the open flower the stigma and 

 anthers are in the same relative positions and are level with the 

 orifice of the corolla.
