Volkamer lemon
Volkamer lemon (Citrus volkameriana), often misspelled Volckamer lemon, is known as 沃 尔卡默柠檬 (wo er ka mo ning meng) in Chinese, citron de Volkamer in French, limone Volkameriano in Italian, and chanh Volkamer in Vietnamese.The specific epithet (volkameriana) honors German botanist Johann Christoph Volkamer.[3] It likely originated in Italy and is most widely grown in the United States and Europe, and to a smaller extent in eastern Asia.[3] Like the Rangpur lime and rough lemon, it is a hybrid of a mandarin orange (Citrus reticulata) and a citron (Citrus medica), with the citron being the pollen parent and the mandarin being the seed parent.The fruit is moderately large (around the size of an orange), seedy, round and slightly elongated, and yellow-orange in color.
