84 STUDIES IN INDIAN TOBACCOS. 



Type II. Plants late, tall; height 150 cms.; lower inter- 

 nodes short, upper ones long ; most of the large leaves borne near 

 the ground ; no large leaves in the upper two-thirds of the plant. 

 Leaves petiolate, petiole is slightly alate in the lower leaves, more 

 so in the upper ones ; the wings are decurrent down the main 

 stem for about 2*5 ems. ; leaves inserted at an angle of 90" and bend 

 downwards from the top of the petiole, asymmetric ; shape varies 

 from ovate to lanceolate according to the position on the stem ; 

 venation acute-angled, secondary veins arising at an angle of 



45° 60° ; apex acute ; margin entire or slightly undulate ; colour 



blue-green ; texture thick ; average length of petiole G cms. ; 

 average length of lamina 49 cms. ; ratio length/breadth 2-5. Lt- 

 Jiorescence leaves petiolate, petiole not alate, inserted at an angle 



of GO" 90', lanceolate ; apex acuminate ; margin generally entire, 



sometimes undulate. Infioresceace raised, side branches borne at 

 regular distances up the stem, parallel to but not as long as the 

 main axis Flowers a deep pink colour which does not fade 

 much ; length 45 mm. Calyx slightly globular and inflated, 

 about one-third the length of the corolla ; teeth moderately long 

 and acute. Corolla with an orifice 8 mm. in diameter, abroad tube, 

 and the transition between the tube and the dilated portion abrupt ; 

 limb not very deeply divided with folds at the junctions of the 

 lobes ; lobes very rounded at the base ; apical points short and 

 somewhat reflexed. Capsule much longer than the persistent 

 calyx, conical ; apex blunt. 



The anthers burst as the flower expands, not in the bud, and 

 at this period are above the stigma. In the fully open flower the 

 burst anthers are about 5 mm. above the stigma and project well 

 beyond the orifice of the corolla.
