Memoirs of the Department of Agriculture in India Botanical Series March 1910 Studies in Indian Tobacco

The objects of the work are threefold : - - 1. The study of the varietal characters and 'the amount of variation in the Indian types of tobacco. [...] produced in tobacco by the soil and the general climatic conditions both On the quality of the crop and also on the form of the plant. [...] The differences are principally of degree only and are hugely bound up with the habit of the plant and the characters of the leaves such as the tone of colour and texture. [...] The differences in habit of the types are due to the length of the intertu. des and also depend on the inflorescence. [...] When the Iwthers burst, the tip of the anther projects slightly above the edge or the stigma, so that the pollen is either deposited on the edge of the stigma or in the tube.
