'''''Brassica rapa''''' (syn. '''''Brassica campestris'''''), commonly known as '''field mustard''' or '''turnip mustard'''<ref>http://www.cas.vanderbilt.edu/bioimages/species/brra.htm</ref> is a [[plant]] widely cultivated as a [[leaf vegetable]] (see [[mizuna]]), a [[root vegetable]], and an [[oilseed]].

Brassica rapa, Linn. Common Turnip. Lvs. prominently lyrate or interrupted below, the root tuberous.—Whatever the origin of the rutabaga and turnip may be, the two plants show good botanical characters. The tubers of the two are different in season, texture and flavor. In the rutabaga, the small Ivs. immediately following the seed-lvs. are sparsely hairy, but all subsequent Ivs. are entirely smooth, densely glaucous blue, thick and cabbage-???, with a fleshy petiole and midrib. In the turnip, the radical Ivs. are always more or less hairy, and they are green and radish-like, thin, with slender petiole, and the Ivs. are much more lyrate, with interrupted Ifts. on the petiole; the small Ivs. following the seed-lvs. are also thinner and narrower and more deeply scalloped. In the rutabaga, the fls. are large and creamy-yellow, whereas in the turnip they are small, yellow and mustard-like, with shorter claws and more spreading calyx. The turnips vary in hairiness, but the cone of expanding lvs., or the "heart- Ivs.," always shows the hairs distinctly, while the heart-lvs. of the rutabagas are normally entirely glabrous, fleshy, and remind one of the young shoots of sea-kale. The turnip usually produces seed freely if the bottoms are left in the ground over winter; and thereby the plant spreads, becoming a true annual and a bad weed, with a slender hard root. Oil-producing forms are var. oleifera, DC.
