Century Dictionary and Cyclopedia
- n raphanus A genus of cruciferous plants, including the radish, type of the tribe Raphaneæ. It is characterized by globose seeds, solitary in the single row of cells formed by constrictions of the pods, which are closed by a pithy substance or sometimes remain continuous throughout. The 6 species are natives of Europe and temperate parts of Asia, and are branching annuals or biennials, with fleshy roots, lyrate lower leaves, and elongated bractless racemes of slender-pediceled white or yellow purplish-veined flowers, followed by erect spreading, thick, and corky or spongy pods. Some species (genus Raphanistrum, Tournefort, 1700) have a short seedless joint below, forming a stalk to the long inflated necklace-like cell which composes the rest of the pod, as R. Landra, a yellow-flowered Italian weed with large radical leaves, eaten as a salad, and R. Raphanistrum, a course weed, the wild or field radish. See radish.
