'''''Berberis darwinii''''' is a species of [[Berberis|barberry]], native to southern [[South America]] in southern [[Chile]] and adjacent southwestern [[Argentina]]. Common names include '''Darwin's Barberry''' and (Chilean Spanish) '''Michay'''.
It is an [[evergreen]] thorny [[shrub]] growing to 3-4 m tall, with dense branches from ground level. The [[leaf|leaves]] are small oval, 12-25 mm long and 5-12 mm broad, with a spiny margin; they are borne in clusters of 2-5 together, subtended by a three-branched spine 2-4 mm long. The [[flower]]s are orange, 4-5 mm long, produced in dense [[raceme]]s 2-7 cm long in spring. The [[fruit]] is a small purple-black [[berry]] 4-7 mm diameter, ripening in summer.
It was discovered (for Western science) in South America in 1835 by [[Charles Darwin]] during the voyage of the 'Beagle'.
It is a popular garden and hedging shrub in the [[British Isles]]. The [[Royal Horticultural Society]] has given it its [[Award of Garden Merit]]. The fruit is edible, though very acidic.
