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.
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.).

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.
