To this same species (N. Tabacum) Havana, 

 East Indian and European tobaccos principally 

 belong. The other important species are : 



Nicotiana Persica. Grown in Persia. This 

 has a white flower and the leaves almost enwrap 

 the stem. It is used almost exclusively as a 

 pipe-smoking tobacco. Some claim that this is 

 only a variant of N. Tabacum. 



Nicotiana Repanda. This is a species of 

 Cuban tobacco entirely different from that 

 grown in the Havana district. It is also called 

 Yara. 



Nicotiana Rustica. A kind of wild growing 

 tobacco principally cultivated in Mexico, and 

 which is claimed as the parent of some of the 

 Turkish, Syrian and Latakia tobaccos although 

 many authorities claim that these tobaccos be- 

 long to the species N. Tabacum. The European 

 tobacco is hardier than the American parent 

 plant. The leaves are smaller. 



N. Rustica. Also includes commpn Hungar- 

 ian and Turkish tobaccos. There are large and 

 small leaved varieties. 



N. Crispa. Grown in Syria and largely in 

 Central Asia. Used as a cigarette tobacco in 

 the Orient. 



It has been stated above that there are many 

 varieties of N. Tabacwm in the U. S. Of these 

 the most important are known to botanists
