'Black Spanish' or 'Black Spanish Round' occur in both round and elongated forms, and are sometimes simply called the black radish (Raphanus sativus L. var. niger (M.) S.K. or L. ssp. niger (M.). D.C. var. albus D.C.) or known by the French name Gros Noir d'Hiver. It dates in Europe to 1548, and was a common garden variety in England and France during the early 19th century. It has a rough, black skin with hot-flavored, white flesh, is round or irregularly pear shaped, and grows to around 10 cm (4 in) in diameter. (Wikipedia)
