138 STUDIES IN INDIAN TOBACCOS. 



Type XXXI. Plants very late, tall ; height 177 cms. ; 

 leaves numerous ; plants very bushy ; lower internodes verj^ short, 

 causing many leaves to lie on or close to the ground, upper inter- 

 nodes long ; inflorescence raised on long branches which bear 

 numerous small leaves. Leaves sessile, inserted at an angle of 

 about 60", the upper part bending downwards, amplexicaul, auri- 

 culate, decurrent for about 2-5 cms. ; shape ovate to elliptical, the 

 lamina reduced in the basal fifth of the leaf; secondary veins arise 

 at an angle of 45° to 60° ; apex acuminate ; lamina with irregular 

 deep undulations (but less so than in type XXXII) ; surface 

 puckered and ridged between the secondary veins ; leaf not 

 expanded but folded on the midrib ; colour yellowish green ; 

 texture medium (thinner than tj'^pe XXXII) ; average length 

 53 cms. ; ratio length/breadth 21. Li florescence leaves similar 

 to the lower leaves. Inflo7'escence raised on long branches which are 

 parallel and equal in length to the main axis. Flowers sparse, a 

 deep pink colour which does not fade ; length 45 mm. Calyx 

 tubular, somewhat inflated, about one-third the length of the 

 corolla ; teeth short and acute. Corolla with an orifice 9 nun. 

 in diameter, tube medium, the transition between the tube and the 

 dilated portion somewhat abrupt ; limb divided to about half its 

 depth, fully expanded with folds at the junctions of the lobes ; 

 lobes rounded at the base with short apical points. Cajosule 

 equal in length to the persistent calyx, cylindrical ; apex blunt. 

 The anthers burst while the flower expands when they are 

 just above the stigma. In the fully open flowers the burst an- 

 thers occupy the same relative position to the stigma and project 

 from the orifice of the corolla.
