ALBERT AND nABRlELLE HOWARD. 143 



Class C. Leaves elliptical, broad ; lamina at the base only 

 slightty reduced ; apex acute ; ratio length to breadth about 2 : 

 inflorescence leaves always similar to the lower leaves. 



This class contains the types which will probably prove the 

 most valuable. The leaves are broad, larg-e and the midribs 

 are not so pronounced as in class A. The distinctive 

 feature is the shape of the leaves which is broad throughout and 

 only slightly narrowed for a very short distance above the base. 

 The broad inflorescence leaves are also very characteristic. On 

 the whole the inflorescence is not much raised, nor as free flower- 

 ing as in class A, while the more compact form of the plants witli 

 large leaves continued up the stem is very difterent to the open 

 habit and basal crowding of the leaves in class B. 



Siih-cla.s.s I. Lower internodes short, upper internodes 

 moderately long. 



Of the seven types included in this sub-class type XL is not 

 very typical, but appeared to be nearer the types in this class than 

 those of any other. Type XXXVI with linear inflorescence 

 leaves is also somewhat anomalous, but the shape of the lower 

 leaves necessitated its inclusion here rather than in class B. 

 Type XXXIV with its very long leaves and type XXXV 

 with exceedingly broad leaves are most distinctive and 

 very easily recognised in the field Type XXXVII in 

 the shape of its leaves is not absolutely typical. The small angle 

 of inset of the leaves and their flatness and stiflfness are character- 

 istic of this form. Type XXXVIII has a peculiarly shaped 

 corolla in which the dilated portion is exceedingly short and the 

 tube very broad. No other type among the Indian tobaccos 

 has a corolla of this shape. Type XXXIX is somewhat like 

 XXXVIII in habit, but is easily distinguished from the latter by 

 the leaf shape.
