Berberis microphylla, common name box-leaved barberry and Magellan barberry, in Spanish calafate and michay and other names, is an evergreen shrub, with simple, shiny box-like leaves. The calafate is native to southern Argentina and Chile and is a symbol of Patagonia. Berberis microphylla should not be confused with Mahonia microphylla, native to China.
