Note 76 — Chapter IX · CULTIVATED PLANTS: CEREAL AND CULINARY PLANTS.

‘Gardener’s Chron. and Agricult. Gazette,’ 1856, p. 729. See, more especially, ibid., 1868, p. 275: the writer asserts that he planted a variety of cabbage (B. oleracea) close to turnips (B. rapa) and raised from the crossed seedlings true Swedish turnips. These latter plants ought, therefore, to be classed with cabbages or turnips, and not under B. napus.
