Mahonia aquifolium, Oregon grape or holly-leaved berberry, is a species of flowering plant in the family Berberidaceae, native to western North America. It is an evergreen shrub growing 1 m (3 ft) to 3 m (10 ft) tall by 1.5 m (5 ft) wide, with pinnate leaves consisting of spiny leaflets, and dense clusters of yellow flowers in early spring, followed by dark bluish-black berries.
Mahonia is a genus of approximately 70 species of evergreen shrubs and, rarely, small trees in the family Berberidaceae, native to eastern Asia, the Himalaya, North and Central America. They are closely related to the genus Berberis and botanists disagree on whether to recognize a separate Mahonia. Many botanists prefer to classify Mahonia as a part of Berberis because several species in both genera are able to hybridize, and because there are no consistent morphological differences between the two groups other than the leaf pinnation. However, recent DNA-based phylogenetic studies retain the two separate genera, by clarifying that unifoliolate-leaved Berberis s.s. is derived from within a paraphyletic group of shrubs bearing imparipinnate evergreen leaves, which are then divided into three genera: Mahonia, Alloberberis, and Moranothamnus ; a broadly-circumscribed Berberis would also be monophyletic.
Berberis, commonly known as barberry, 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. Species diversity is greatest in South America and Asia; Europe, Africa and North America have native species as well. The best-known Berberis species is the European barberry, Berberis vulgaris, which is common in Europe, North Africa, the Middle East, and central Asia, and has been widely introduced in North America. Many of the species have spines on the shoots and all along the margins of the leaves.
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 candidula is a species of plant in the family Berberidaceae. It is endemic to China, native to the provinces of Hubei and Sichuan.
Mahonia microphylla is a shrub in the Berberidaceae first described as a species in 1999. It is endemic to Guangxi Province in China.
Mahonia oiwakensis is a species of plant in the barberry family, Berberidaceae. It is native to Taiwan, China and Myanmar, where it occurs at elevations of 600 to 3800 m. It has recently been found naturalized in South Africa.
Berberis dictyophylla, the netleaf barberry, is a deciduous shrub in the genus Berberis which is native to Western China.
Mahonia duclouxiana is a plant species native to India, Myanmar (Burma), Thailand, and southern China.
Berberis haematocarpa, Woot. with the common names red barberry, red Mexican barbery, Colorado barberry and Mexican barberry, is a species in the Barberry family in southwestern North America. It is also sometimes called algerita, but that name is more often applied to its relative, Mahonia trifoliolata.
Berberis amoena is a shrub native to the Sichuan and Yunnan provinces of China. It is found at elevations of 1600–3100 m.
Berberis bealei, also known as leatherleaf mahonia, Beale's barberry, or Oregon grape, is a species of evergreen shrub native to mainland China. The species has been regarded as the same species as Berberis japonica, native to Taiwan, but the two differ consistently in certain floral and leaf characters. Both species are widely cultivated in many countries as ornamentals. Berberis bealei has reportedly escaped cultivation and become established in the wild in scattered places in the south-eastern United States from Arkansas to Florida to Delaware.
Berberis sikkimensis is a plant species native to the high Himalayas at elevations of 2000–3000 m. It is known from Sikkim, Nepal, Bhutan, Tibet and Yunnan.
