Berberis

 ( Berberidaceae Genera ) 

Berberis (), commonly known as barberry,

is a large genus of deciduous and evergreen from tall, found throughout Temperateness and subtropical regions of the world (apart from Australia). 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. Flora of China Vol. 19 Page 715 小檗属 xiao bo shu Berberis Linnaeus, Sp. Pl. 1: 330. 1753.

Description The genus Berberis has dimorphic shoots: long shoots which form the structure of the plant, and short shoots only long. The leaf on long shoots are non-Photosynthesis, developed into one to three or more spines

long. The bud in the axil of each thorn-leaf then develops a short shoot with several normal, photosynthetic leaves. These leaves are long, simple, and either entire, or with spiny margins. Only on young seedlings do leaves develop on the long shoots, with the adult foliage style developing after the young plant is 1–2 years old.

Many deciduous species, such as Berberis thunbergii and B. vulgaris, are noted for their attractive pink or red autumn colour. In some evergreen species from China, such as B. candidula and B. verruculosa, the undersides of the leaves are brilliant white, a feature valued horticulturally. Some horticultural variants of B. thunbergii have dark red to violet foliage. Such as B. thunbergii f. atropurpurea 'Admiration', and B. thunbergii f. atropurpurea 'Atropurpurea Nana'.

The flowers are produced singly or in of up to 20 on a single flower-head. They are yellow or orange, long, are usually six, rarely three or nine and there are six in alternating whorls of three, the sepals usually coloured like the petals. The fruit is a small berry long, ripening red or dark blue, often with a pink or violet waxy surface bloom; in some species, they may be long and narrow, but are spherical in other species.

Some authors regard the compound-leaved species as belonging to a different genus, Mahonia. There are no consistent differences between the two groups other than the leaf pinnation ( Berberis sensu stricto appear to have simple leaves, but these are in reality compound with a single leaflet; they are termed "unifoliolate"), and many botanists prefer to classify all these plants in the single genus Berberis.Loconte, H., & J. R. Estes. 1989. Phylogenetic systematics of Berberidaceae and Ranunculales (Magnoliidae). Systematic Botany 14:565-579.Marroquín, Jorge S., & Joseph E. Laferrière. 1997. Transfer of specific and infraspecific taxa from Mahonia to Berberis. Journal of the Arizona-Nevada Academy of Science 30(1):53-55.Laferrière, Joseph E. 1997. Transfer of specific and infraspecific taxa from Mahonia to Berberis. Botanicheskii Zhurnal 82(9):96-99. However, a DNA-based Phylogenetics study retains the two separate genera, by clarifying that unifoliolate-leaved Berberis s.s. is derived from within a paraphyly group of shrubs bearing imparipinnate evergreen leaves, which the paper then divides into three genera: Mahonia, Alloberberis (formerly Mahonia section Horridae), and Moranothamnus (formerly Berberis claireae); it confirms that a broadly-circumscribed Berberis (that is, including Mahonia, Alloberberis, and Moranothamnus) is monophyly.

Ecology Berberis species are used as food plants by the of some Lepidoptera species, including the barberry carpet moth ( Pareulype berberata), and mottled pug ( Mottled pug).

Berberis species can infect wheat with stem rust, a serious fungal disease of wheat and related grains. Berberis vulgaris (European barberry) and Berberis canadensis (American barberry) serve as alternate host species of the rust fungus responsible, the fungus Puccinia graminis. For this reason, cultivation of B. vulgaris is prohibited in many areas, and imports to the United States are forbidden. The North American B. canadensis, native to Appalachia and the Midwest United States, was nearly eradicated for this reason, and is now rarely seen extant, with the most remaining occurrences in the Virginia mountains.

Some Berberis species have become invasive species when planted outside of their native ranges, including B. glaucocarpa and B. darwinii in New Zealand (where it is now banned from sale and propagation), and B. vulgaris and green-leaved B. thunbergii in much of the eastern United States.

Japanese barberry is considered an invasive plant in 32 US states. It is deer-resistant because of its taste and is favored as a shelter for ticks capable of transmitting lyme disease.

Cultivation Several species of Berberis are favored as garden shrubs, grown for such features as ornamental leaves, yellow flowers, or red or blue-black berries. Numerous cultivars and Hybrid plant have been selected for garden use. Low-growing Berberis plants are also commonly planted as pedestrian barriers. Taller-growing species are valued for crime prevention; being dense and viciously spiny, they are effective barriers to burglars; accordingly, they may be planted below vulnerable windows, and used as hedges. Many species are resistant to predation by deer.

Species in cultivation include:

• B. darwinii
• B. dictyophylla
• B. julianae
• B. thunbergii
• B. verruculosa

The following hybrid selections have gained the Royal Horticultural Society's Award of Garden Merit:

• B. 'Georgei'
• B. × lologensis 'Apricot Queen'
• B. × media 'Red Jewel'

• B. × stenophylla 'Corallina Compacta'
• B. × stenophylla (golden barberry)

Uses

Culinary Berberis vulgaris grows in the wild in much of Europe and West Asia. It produces large crops of edible berries, rich in vitamin C, but with a sharp acid flavor. In Europe, for many centuries the berries were used for culinary purposes much as citrus peel is used. The country in which they are used the most is Iran, where they are referred to as zereshk (زرشک) in Persian language. The berries are common in Iranian cuisine in rice dishes, such as zereshk polo (a dish of rice cooked in the Persian style with saffron and barberries, often served with chicken) and morassa polo (literal translation "bejewelled rice", an opulent dish of rice with barberries and slivers of pistachio, almond, and orange peel) and as a flavouring for poultry. Because of their sour flavor, they are sometimes cooked with sugar before being added to Persian rice. Iranian markets sell dried zereshk. By virtue of their limited availability, specialised growing conditions, and the complexity of the harvesting process, they are considered expensive and so are served in the finest of Persian dishes. In Russia and Eastern Europe, it is sometimes used in jams as a source of pectin (especially with mixed berries). An extract of barberries is a common flavoring for soft drinks, candies, and sweets.

Berberis microphylla and B. darwinii (both known as calafate and michay) are two species found in Patagonia in Argentina and Chile. Their edible purple fruit are used for jams and infusions.

Traditional medicine and adverse effects The dried fruit of Berberis vulgaris is used in herbal medicine. The chemical constituents include Isoquinoline , especially berberine. A full list of phytochemicals was compiled and published in 2014. Mokhber-Dezfuli N, Saeidnia S, Gohari AR, Kurepaz-Mahmoodabadi M. Phytochemistry and pharmacology of berberis species. Pharmacogn Rev. 2014;8(15):8–15. doi:10.4103/0973-7847.125517 The safety of using berberine for any condition is not adequately defined by high-quality clinical research.

Its potential for causing is high, including untoward interactions with prescription drugs, reducing the intended effect of established therapies. Nausea, vomiting, diarrhea, dizziness, and fainting are possible effects, particularly with high doses. It is particularly unsafe for use during pregnancy.

Other uses Historically, yellow dye was extracted from the stem, root, and bark.

The thorns of the barberry shrub have been used to clean ancient gold coins, as they are soft enough that they will not damage the surface but will remove corrosion and debris.

The acidic young leaves are sometimes chewed for refreshment by parched hikers.
