Rapeseed Brassica napus, also known as rape,[1] oilseed rape,[1] rapa, rappi, rapaseed and, in the case of one particular group of cultivars, canola, is a bright-yellow flowering member of the family Brassicaceae mustard or cabbage family, consumed in China 油菜籽: Mandarin Pinyin yóucài; Cantonese:yau choy and Southern Africa as a vegetable. The name derives from the Latin for turnip, rāpa or rāpum, and is first recorded in English at the end of the 14th century. Older writers usually distinguished the turnip and by the adjectives `round` and `long` -`rooted`, respectively.[2] Rutabagas, Brassica napobrassica, are sometimes considered a variety of B. napus. Some botanists also include the closely related B. rapa within B. napus.
