Berberis darwinii, Darwin's barberry, [3] is a species of flowering plant in the family Berberidaceae, [4] native to southern Chile and Argentina and naturalized elsewhere. Regional vernacular names include michay , calafate , and quelung . [ 5 ]
Berberis (/ ˈ b ɜːr b ər ɪ s /), commonly known as barberry, [1] [2] is a large genus of deciduous and evergreen shrubs from 1–5 m (3.3–16.4 ft) tall, found throughout temperate and subtropical regions of the world (apart from Australia).
Therefore, many species have two scientific names, one in Berberis, the other in Mahonia, each used by botanists on one side of the debate. A third generic name, Odostemon , can be found in older literature.
The APG IV system of 2016 recognises the family and places it in the order Ranunculales in the clade eudicots. [2]In some older treatments of the family, Berberidaceae only included four genera (Berberis, Epimedium, Mahonia, Vancouveria), with the other genera treated in separate families, Leonticaceae (Bongardia, Caulophyllum, Gymnospermium, Leontice), Nandinaceae (Nandina), and ...

Older sources, particularly botanical works published before the 1950s, used a different convention: if the second part of the name was derived from a proper noun, e.g., the name of a person or place, a capital letter was used. Thus, the modern form Berberis darwinii was written as Berberis Darwinii.
The plants contain berberine, a compound found in many Berberis and Mahonia species which causes vomiting, lowered blood pressure, reduced heart rate, lethargy, and other ill effects when consumed. [15] The genus name, Mahonia, derives from Bernard McMahon, one of the stewards of the plant collections from the Lewis and Clark Expedition.
