Historical publication digitized 2013 by Internet Archives [for Agriculture and Agri-Food Canada]. Includes bibliographical references. "Under the single species, N. tabacum, is grouped as varied an assemblage of varieties, forms, and suspected hybrids, as were ever brought together underone specific name. There is no exact agreement as to what are the simplest expressions of the fundamental types. No attempt is being made in this bulletin to deal with this phase of the problem. It is essential, however, and it is hoped that some order will be brought out of chaos by studying these forms and varieties which are more directly the result of hybridization and selection than of acclimatization and adaptation. The various forms and varieties are accepted as they exist today, and an endeavour is made to study the individual characteristics of these forms and varieties as they are known and grown in the tobacco industry"--p. 5-6. gccst Tobacco industry Haslam, R.
