128 STUDIES IN INDIAN TOBACCOS. 



Type XXV. Plants very late, tall ; height 165 cms. ; leaves 

 few ; lower internodes very short, a few leaves borne on the ground, 

 upper internodes very long ; inflorescence much raised on long- 

 slender branches ; flowers sparse. Leaves sessile, inserted at an 

 angle of 60', the upper half becoming horizontal, amplexicaul, 

 slightly auriculate, decurrent, the decurrent portion very narrow ; 

 shape elliptical, lamina reduced in the basal fifth of the leaf ; 

 secondary veins arise at an angle of 45° ; apex acute : margin 

 with deep irregular undulations ; surface puckered ; leaf not 

 expanded but folded on the midrib ; colour yellowish green ; 

 texture coarse to medium ; average length 54 cms. ; ratio 

 length /breadth 2 '8. Infiorescence leaves similar to the lower 

 leaves, but narrower and not amplexicaul or decurrent. Inflores- 

 cence much raised on long slender branches, which are parallel 

 to the main stem. Flowers sparse, a very deep pink colour which 

 does not fade ; length 45 mm. Calyx tubular, inflated, less than 

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

 Corollct with a wide orifice (11 to 12 mm. in diameter), tube broad, 

 the transition between the tube and the dilated portion gradual : 

 limb divided to about half its depth, fully expanded with folds at 

 the junctions of the lobes ; lobes rounded at the base with very 

 short apical points. Capsule equal in length to the persistent 

 calyx, cylindrical ; apex blunt. 



The anthers burst as the flower expands when they are 

 approximately level with the stigma. The stigma and empty 

 anthers retain their relative positions in the fully open flower and 

 are level with the orifice of the corolla.
