22 STUDIES IN INDIAN TOBACCO 



Type 11. Plants very early ; height 142cms. Leaves 

 inserted at an angle of about (30°, subcordate ; apex obtuse ; 

 margin slightly undulate ; surface tiat : colour blue-green ; 

 average length of petiole 7"5cnis. ; average length of lamina 

 2ocms. ; ratio length / breadth = 1 "1 1. lufiore.sceuce leavers inserted 

 at an angle of about 45', elliptical to lanceolate ; apex somewhat 

 obtuse ; margin slightly undulate ; surface flat. Injiorescence 

 open ; the secondary branches long and slender, almost as long as, 

 and running somewhat parallel to, the main axis. Flowers sparse, 

 medium in size ; outline shows a decided constriction. Calyjc 

 3^ellowish green, globular, giving the appearance of a constriction 

 in the outline of the flower ; midrib of sepals inconspicuous ; teeth 

 short and obtuse. Corolla with a slightly divided limb which is 

 quite flat and fully expanded ; margins of the limb and apiculse 

 recurved. (Plate V, 33). Capsule medium in size, roundly 

 conical, about two-thirds covered by the persistent calyx ; apex 

 rounded and umbilicate. 



In the flowers of this type cross and self-pollination are 

 both possible. When the anthers burst, the tip of the anther 

 projects slightly above the edge of the stigma, so that the pollen 

 is either deposited on the edge of the stigma or in the tube. 

 When the flower opens and the stamens have shed most of their 

 pollen, the burst anthers are clustered round the style below the 

 stigma. Under bag this type sets very few seeds.
