White-leaf (Forf. Nov. Gen.) a genus of the monogynia order, belonging to the pentandria clas of plants. The capsule is trilocular; the nectarium is pyramidal, pentagonous, and the length of the corolla. There is but one species, the nitidum or glosty, a native of New Caledonia. This genus has great affinity with the ivy; but differs in the nectarium, and perhaps in the fruit.
