Inflorescence: cyme, raceme, panicle, cluster, or flowers 1; bractlets on pedicel ("pedicel bractlets") generally 0--3(many), subtended by bract or generally not. Flower: generally bisexual, radial; hypanthium free or fused to ovary, saucer- to funnel-shaped, subtending bractlets ("hypanthium bractlets") 0--5, alternate sepals; sepals generally 5; petals generally 5, free; stamens (0,1)5--many, anther pollen sacs generally 2; pistils (0)1--many, simple or compound, ovary superior to inferior, styles 1--5. Fruit: 1--many per flower, achene (fleshy-coated or not), follicle, drupe, or pome with generally papery core, occasionally drupe-like with 1--5 stones. Seed: generally 1--5 (per fruit, not per flower). Genera In Family: 110 genera, +- 3000 species: worldwide, especially temperate; many cultivated for ornament, fruit, especially Cotoneaster, Fragaria, Malus, Prunus, Pyracantha, Rosa, Rubus.

Common Name: SERVICE-BERRY Habit: Shrub, small tree. Stem: bark gray- to red-brown; overwintering buds ovate to lanceolate, +- red to +- purple. Leaf: simple, deciduous; stipules deciduous. Inflorescence: raceme, cluster (panicle), flowers 3--16+; pedicel bractlets generally 1--2. Flower: hypanthium bell- to urn-shaped, bractlets 0; sepals persistent; petals erect to spreading, white (suffused with red); stamens +- 10--20; ovary inferior, 2--5-chambered, styles 2--5. Fruit: pome of 2--5 papery segments, berry-like, generally spheric, generally blue-black. Etymology: (Latin: from old French common name) Note: Fruit of some species used by Native Americans for food. Unabridged Note: Variation in Amelanchier in western North America not studied as extensively as in eastern North America, where hybridization, polyploidy, and apomixis have contributed to considerable taxonomic complexity (Campbell & Wright 1996 Folia Geobot Phytotax 31:345--354; http://biology.umaine.edu/Amelanchier). eFlora Treatment Author: Christopher S.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
