Brassica rapa species. Since the turnip had been named first by Linnaeus, the name "Brassica rapa" was adopted. Many butterflies, including the small white, pollinate the "B. rapa" flowers. Brassica rapa Brassica rapa is a plant consisting of various widely cultivated subspecies including the turnip (a root vegetable); napa cabbage, bomdong, bok choy, and cime di rapa (leaf vegetables); and "Brassica rapa subsp. oleifera", an oilseed which has many common names, including "turnip rape", "field mustard", "bird rape", and "keblock". The oil made from the seed is sometimes also called "canola" or "colza", which is one reason why it is sometimes confused
Fat choy Fat choy Fat choy (; "Nostoc flagelliforme") is a terrestrial cyanobacterium (a type of photosynthetic bacteria) that is used as a vegetable in Chinese cuisine. When dried, the product has the appearance of black hair. For that reason, its name in Chinese means "hair vegetable." When soaked, fat choy has a soft texture which is like very fine vermicelli. Fat choy grows on the ground in the Gobi Desert and the Qinghai Plateau. Over-harvesting on the Mongolian steppes has furthered erosion and desertification in those areas. The Chinese government has limited its harvesting, which has caused its price to increase.
