The rat-tail radish (Chinese: t Chinese: {{linktext|鼠尾蘿蔔, s Chinese: {{linktext|鼠尾萝卜, shǔwěi luóbó), serpent radish, or tail-pod radish is a plant of the radish genus Raphanus named for its edible seed pods.[1] Linnaeus described it as the species Raphanus caudatus; it is now sometimes treated as a variety of the common radish (R. sativus), either caudatus or mougri.
It is found primarily in India and Southeast Asia and is believed to have originated in China.[2] It was first known in the West no later than 1815, when introduced into England from Java.[3]
