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 by the names, Nicotiana Tabacum Macrophylla and Nicotiana Tabacum Angustifolia.
Maryland tobacco belongs to the Macrophylla variety and there are many other types differing from each other according to shape of the leaf, size of the stalk, etc.
Virginian tobacco is of the Angustifolia variety, and of this also there are many different types.
Most European and other grown tobaccos have been raised from original plants of the Maryland and Virginian varieties.
It should be remembered that there is no essential difference in cigar, pipe smoking or cigarette tobaccos. The differences are physical only. All kinds may be obtained from the same species or even the same variety of the species by suitable culture and crossing.
