Elaeocarpus Acmocarpus

''Elaeocarpus'' is a genus of nearly five hundred species of flowering plants in the family Elaeocarpaceae native to the Western Indian Ocean, Tropical and Subtropical Asia, and the Pacific. Plants in the genus ''Elaeocarpus'' are trees or shrubs with simple leaves, flowers with four or five petals usually, and usually blue fruit.

Description

Plants in the genus ''Elaeocarpus'' are mostly evergreen trees or shrubs, a few are epiphytes or lianes, and some are briefly deciduous. The leaves are arranged alternately, simple (strictly compound with only one leaflet) with a swelling where the petiole meets the lamina, often have toothed edges, usually have prominent veins and often turn red before falling. The flowers are usually arranged in a raceme, usually bisexual, have four or five sepals and petals and many stamens. The petals usually have finely-divided, linear lobes. The fruit is a oval to spherical drupe that is usually blue, sometimes black, with a sculptured endocarp.

Taxonomy and naming

The genus ''Elaeocarpus'' was first formally described in 1753 by Carl Linnaeus in ''Species Plantarum'', although Johannes Burman published an illustration of "''Elaecarpus serrata''" in his book ''Thesaurus zeylanicus'', but without a description of the genus. The first species described by Linnaeus (the type species) was ''Elaeocarpus serratus''. The name ''Elaeocarpus'' is derived from Greek and means ‘olive-fruited’.
