Berberis x bristolensis


[ Back to top ]

Family Berberidaceae

Herbs or shrubs [trees ], perennial , evergreen or deciduous, sometimes rhizomatous . Stems with or without spines. Leaves alternate, opposite, or fascicled, simple , 2-3-foliolate, or 1-3-pinnately or 2-3(-4) -ternately compound ; stipules present or absent; venation pinnate or palmate. Inflorescences terminal or axillary , racemes , cymes, umbels (or umbel-like), spikes, or panicles, or flowers solitary or in pairs, flowers pedicellate or sessile. Flowers bisexual , inconspicuous or showy, radially symmetric ; stipitate glands absent (except in Vancouveria ) ; sepaloid bracteoles 0-9; perianth sometimes absent ( Achlys ), more frequently present, 2- or 3-merous, or sepals and petals intergrading ( Nandis ) ; sepals 6, distinct , often petaloid and colored , not spurred ; petals 6-9, distinct, plane or hooded ; nectary present; stamens 6; anthers dehiscing by valves or longitudinal slits; ovary superior, apparently 1-carpellate; placentation marginal or appearing basal; style present or absent, sometimes persistent in fruit as beak . Fruits follicles, berries , or utricles. Seeds 1-50, sometimes arillate ; endosperm abundant; embryo large or small; mature seeds elevated on elongating stalk in Caulophyllum.

Genera 15, species ca. 650 (8 genera, 33 species in the flora ) : widespread, well represented in the north temperate zone.

Berberidaceae presents several interesting biogeographic features. Achlys is disjunct from western North America to east Asia with few morphologic differences between taxa. Diphylleia, Jeffersonia, and Podophyllum, each with a single eastern North American species, exhibit wide disjunctions to east Asia. Caulophyllum has three species, one in east Asia and two in the flora. Vancouveria is endemic to northwestern United States with nearest relations to Epimedium Linnaeus (H. Loconte and J. R. Estes 1989b; W. T. Stearn 1938), an exclusively Eastern Hemisphere genus.

Nandina, Berberis, Epimedium, and Podophyllum are cultivated.

The perianth of Berberidaceae is commonly composed of three distinct types of organs, but terminology for the organs varies from author to author. In our treatment, we refer to the small, outer parts as bracteoles (collectively forming a calyculus) ; the large, middle parts as sepals; and the innermost parts, which are commonly nectariferous , as petals. Some authors have referred to the bracteoles as outer sepals and to the petals as staminodes.[1]

Genus Berberis

Shrubs or subshrubs , evergreen or deciduous, 0.1-4.5(-8) m , glabrous or with tomentose stems. Rhizomes present or absent, short or long, not nodose . Stems branched or unbranched, monomorphic or dimorphic , i.e. , all elongate or with elongate primary stems and short axillary spur shoots . Leaves alternate, sometimes leaves of elongate shoots reduced to spines and foliage leaves borne only on short shoots; foliage leaves simple or 1-odd-pinnately compound ; petioles usually present. Simple leaves: blade narrowly elliptic , oblanceolate , or obovate , 1.2-7.5 cm. Compound leaves: rachis, when present, with or without swollen articulations ; leaflet blades lanceolate to orbiculate, margins entire, toothed , spinose , or spinose-lobed; venation pinnate or leaflets 3-6-veined from base . Inflorescences terminal , usually racemes , rarely umbels or flowers solitary. Flowers 3-merous, 3-8 mm; bracteoles caducous , 3, scalelike; sepals falling immediately after anthesis , 6, yellow; petals 6, yellow, nectariferous ; stamens 6; anthers dehiscing by valves ; pollen exine punctate ; ovary symmetrically club-shaped; placentation subbasal ; style central. Fruits berries , spheric to cylindric-ovoid or ellipsoid , usually juicy, sometimes dry, at maturity. Seeds 1-10, tan to red-brown or black; aril absent. x = 14.

Species ca. 500: almost worldwide.

Many species of Berberis are grown as ornamental shrubs. Some species harbor the black stem-rust of wheat ( Puccinia graminis Persoon) ; the sale or transport of susceptible or untested species is illegal in the United States and Canada. Data on susceptibility of Berberis spp. to infection by Puccinia graminis was supplied by Dr. D. L. Long, U.S. Department of Agriculture (pers. comm. ) .

The berries of many species are edible and frequently are used for jam and jelly.[2]
