Ceylon sumach; a genus of the decandria order, belonging to the monodelphia class of plants. There is but one species, viz., the monocarpus. This is a native of India, and rises with a ligneous stalk eight or ten feet high, which is hard, rigid, and covered with a black bark, and divides upward into two or three branches garnished with trifoliate leaves, having long footstalks placed alternate. It is propagated by cuttings, and is to be treated in the same manner with other tender exotics.
