Higher Taxonomy
Family: RosaceaeView DescriptionDichotomous Key
Common Name: ROSE FAMILY
Habit: Annual to tree, glandular or not. Leaf: simple to palmately or pinnately compound, generally alternate; stipules free to fused (0), persistent to deciduous. 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 ornamental, fruit, especially Cotoneaster, Fragaria, Malus, Prunus, Pyracantha, Rosa, Rubus. Note: Number of teeth is per leaf or leaflet, not per side of leaf or leaflet, except in Drymocallis.

Genus: PrunusView DescriptionDichotomous Key


Habit: Shrub, tree. Leaf: simple, alternate or clustered on short-shoots, entire to serrate, generally glabrous, generally glandular on teeth and at blade-petiole junction, veins pinnate; stipules deciduous. Inflorescence: raceme, umbel-like or subsessile cluster, or fls 1; pedicel bractlets 0. Flower: hypanthium cup- to urn-shaped, deciduous in fruit, bractlets 0; sepals erect to reflexed; stamens generally 10--30, generally in 2+ whorls; pistil 1, ovary superior, chamber 1, ovules 2, style 1, stigma +- spheric or disk-like. Fruit: drupe, generally ovoid to spheric.
Species In Genus: 200+ species: worldwide, especially northern temperate. Etymology: (Greek: plum, prune) Toxicity: Seeds of many species +- TOXIC from production of hydrocyanic acid. Note: Many cultivated for wood, ornamental, edible fruit; some persisting near human habitations, some possibly naturalized (e.g., Prunus laurocerasus L.).

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.
