(Jroiqj II. Plants with sessile leaves. 



Class A. Lower leaves linear or lanceolate ; ratio length to 

 breadth 3 to 4*5 ; inflorescence leaves linear. 



This class contains thirteen types of narrow-leavecl tobaccos. 

 Several of the kinds are dwarf forms and no ver}?- tall types 

 occur." For several reasons it seems probable that the economic 

 value of the tobaccos in this class is not very high. In the 

 majorit}^ of the forms, the leaves are borne on or near the ground, 

 and this causes them to be torn or damaged easil}', especiall}^ 

 those with long, slender tips. They are also liable to be much 

 deteriorated b}^ contact with the soil. Moreover, the leaves are 

 generally undulating not flat and the midrib is pronounced and 

 thick. 



Sub-class 1. Leaves linear and very thick ; ratio leno-th to 

 breadth more than 4. 



The three types contained in this sub-class are most distinc- 

 tive and can be easily recognised by their exceedingly thick 

 needle-like leaves. The leaves are dark green with conspicuous 

 light-coloured veins and stand out stifliy and horizontally. Thev 

 are of no value except for the manufacture of snufl'. The three 

 types are easily distinguished among themselves b}- ditterences 

 in habit.
