摘要：

Berberis is the largest genus in the Berberidaceae, comprising more than 500 species. It is now recognised to include all of the compound-leaved species formally ascribed to Mahonia, as well as simple-leaved species comprising Berberis s. str. Berberis s.l. has a mainly Northern Hemisphere distribution, with a centre of diversity in the Sino-Himalaya region, while Berberis s. str. extends into South America where it has a secondary centre of diversity. We analyzed nuclear ITS and chloroplast ndhF sequence data from 68 accessions of Berberis s.l. The results support the monophyly of Berberis s.l., but compound-leaved Berberis are shown to be paraphyletic. The analysis supports Berberis higginsae, a member of North American B. sect. Horridae, as sister to all other Berberis species. Our results, interpreted in the light of fossil evidence, suggest a North American origin of Berberis s.l., but the area of origin of the simple-leaved group remains uncertain.
