Mahonia

**Definition:** A plant genus in the family BERBERIDACEAE. Oregon Grape was discovered in North America and classified by Pursh as a BERBERIS but Nuttall claimed it is different enough to call it a new genus, MAHONIA. Now botanists insist on Berberis while horticulturists stay with this genus. It is a source of BERBERINE.
