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 common 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. Tabacum in the U. S. Of these 
the most important are known to botanists
