Note 60 — Chapter I
Reading edition
In turnips and swedes the swelled part is, as in the radish, the lower part of the stem, below the cotyledons, with a more or less persistent part of the root. (See Turpin. Ann. Sc. Natur., ser. 1, vol. xxi.) In the Kohl-rabi (Brassica oleracea caulo-rapa) it is the stem.
