Native of Formosa on mountains up to 13,000 ft altitude. First introduced to this country apparently by W. R. Price, who collected it on Mt Morrison in 1912 and raised it from seeds at Pen Moel, near Chepstow. It was collected by Wilson in October 1918, and seed was distributed by the Arnold Arboretum the following spring. From this seed the late Marquis of Headfort raised the plants from which the Botanical Magazine plate was prepared. It is a handsome barberry, especially in autumn, when, in addition to the beauty of its fruits, its foliage assumes brilliant shades of scarlet and gold. It is related to B. diaphana.
