Excerpt from Science and Practice in Farm Cultivation The facility with which different sorts of roots may be procured can readily be understood from the many varieties, not only of turnip which may perhaps be considered as an original species - but also of swede, which is a hybrid of the turnip and rape plant. Of the former we have more than thirty sorts grown by the farmer, and as many peculiar to the garden whilst there are probably more than twenty well-recognized sorts of Swedes. Of beets, with mangel-wurzel, we have almost as great a variety; so also of carrots. Of parsnips we have fewer varie ties, to which may now be added the new form called the Student parsnip, the growth of which is so interesting that we shall here give a short history of its production, as an illustration of the origin of root crops.
