Description

[edit]

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.[2][3][4]

Taxonomy and naming

[edit]

The genus Elaeocarpus was first formally described in 1753 by Carl Linnaeus in Species Plantarum,[5][6] although Johannes Burman published an illustration of "Elaecarpus serrata" in his book Thesaurus zeylanicus, but without a description of the genus.[7] The first species described by Linnaeus (the type species) was Elaeocarpus serratus.[5] The name Elaeocarpus is derived from Greek and means ‘olive-fruited’.[8]
