STUDIES IN INDIAN TOBACCOS. 



Type IV. Plants late ; height 135cms. Leaves inserted at 

 an angle of 45 , subcordate ; apex obtuse ; margin undulate ; 

 surface more puckered than in t^^pe III ; colour blue-green ; 

 average length of petiole 7cms. ; average length of lamina •J9*5cms. ; 

 ratio length/breadth = 1 'OS. Inflorescence leaves inserted at 

 an angle of 30^ ovate to elliptical ; apex obtuse to acute ; 

 margin slightly undulate ; surface flat.. Inflorescence open ; the 

 secondary branches long and slender, but not so long nor so 

 parallel to the main axis as in types I & II. Flowers sparse, 

 medium in size, but larger and coarser than in type III ; no 

 apparent constriction in the outline. Calyx loose and baggy : 

 teeth short and obtuse. Corolla with distinct lobes, limb very 

 crumpled ; apiculye inconspicuous. Capside medium in size, 

 roundly conical, about one-third covered by the persistent calyx ; 

 apex rounded, not markedly umbilicate. 



The plants of this type are much stouter and coarser looking 

 than those of the other types in this group. 



In this type the anthers surround the stigma and both 

 self- and cross-pollination are possible. Good setting is obtained 

 under bag.
