BRASSICA CAMPESTRIS (Rutabaga or Swede Tumip) (Fig. 142) Description.—This species resembles very closely B. rapa, the common turnip. Rutabagas or "Swedes," have a short stem or "neck" at the upper part of the vegetable. It is this character which easily distinguishes the rutabaga vege- table from that of turnip. The flesh is solid and yellow or orange in color. The first leaves are bluish white, and all leaves have thick, fleshy petioles.
