Perennial herb, shrub, [tree], generally rhizomed, caudexed or not, glabrous, glaucous, or hairy. Stem: spreading to erect, branched or not. Leaf: simple, 1–3-ternate, or pinnately compound, basal and cauline, generally alternate, deciduous or evergreen, petioled, stipuled. Inflorescence: generally raceme, spike, or panicle, scapose, terminal, or axillary. Flower: generally bisexual, radial; sepals 6–18 or 0, generally in whorls of 3; petals generally 6, in 2 whorls of 3, or 0; stamens 6–12(13), free or fused at base, in 2 whorls or not, anthers dehiscent by flap-like valves or longitudinal slits; ovary superior, chamber 1, ovules generally 1–10, style 1 or 0, stigma flat or spheric. Fruit: berry, capsule, achene [follicle].
16 genera, ± 670 species: temperate, tropics worldwide; some cultivated (Berberis, Epimedium, Nandina (heavenly bamboo), Vancouveria). [Wang 2007 Syst Bot 32:731–742] Lower sepals sometimes called "bracteoles," inner petals "staminodes". —Scientific Editor: Thomas J. Rosatti.

Key to Berberidaceae
Shrub, generally rhizomed. Stem: spreading to erect, branched, spiny or not, vine-like or not; inner bark, wood generally bright yellow; over-wintering bud scales deciduous or not. Leaf: simple or pinnately compound, cauline, alternate, generally leathery, generally persistent; leaflets generally 3–11, ± round to lanceolate, generally spine-toothed. Inflorescence: raceme, axillary or terminal. Flower: sepals 9 in 3 whorls of 3; petals 6 in 2 whorls of 3, bases generally glandular; stamens 6; ovules 2–9, stigma ± spheric. Fruit: berry, spheric to elliptic, generally purple-black.Key to Berberis
± 600 species: temperate worldwide. (Latin: ancient Arabic name for barberry) Roots often TOXIC: spines may inject fungal spores into skin. [Kim 2004 J Plant Res 117:175–182] Contact with filament causes stamen to snap inward, possibly to deposit pollen on pollinator.
Unabridged references: [Moran 1982 Phytologia 52:221–226, for relationship between Berberis, Mahonia.]
Stem: upper reclining to erect; bud scales generally deciduous. Leaf: cauline, not crowded, 9–20 cm; petiole generally 1–3 cm; leaflets generally 7–11, terminal 3–7 cm, 2–4.5 cm wide, ovate to wide-elliptic, wavy, base ± lobed to truncate, tip acute to obtuse except tooth, margin entire to generally dentate to serrate, spines 15–23 per side, 0.1–2 mm. Inflorescence: 3–7.5 cm, dense; axis internodes 2–4 mm in flower. Fruit: 6–8 mm diam, ovoid to obovoid, glaucous, blue-purple. Seed: 3–4 mm. Relationship to Berberis aquifolium needs study. [Online Interchange]
Plant generally < 2 m. Stem: upper generally erect. Leaf: entire or generally serrate; leaflet margins generally wavy, spines generally > 1 mm. Inflorescence: 3.5–7.5 cm.
Rocky slopes, conifer forest, oak woodland, chaparral; < 1900 m. Northwestern California, Central Western California, Western Transverse Ranges, San Gabriel Mountains, Peninsular Ranges; to British Columbia, Baja California. Intergrades with Berberis aquifolium var. dictyota. Feb–May [Online Interchange]
