Overview

Comprehensive Description

Description

Trees or shrubs, sometimes armed. Stipules 0. Leaves alternate, simple, entire; midrib impressed above, prominent below (in ours). Flowers actinomorphic, unisexual or bisexual. Calyx cup-shaped, margin entire or lobed. Petals 3-5(-6), free or united, valvate. Stamens as many as or more numerous than the petals; all fertile or some sterile (i.e. staminodes may be present). Ovary superior or semi-inferior, usually 3-5-locular at base. Stigma lobed or capitate. Fruit a 1-seeded drupe (in ours).

Olacaceae

Olacaceae is a family of flowering plants in the order Santalales. They are woody plants, native throughout the tropical regions of the world.

The 1998 APG system and the 2003 APG II system assign it to the order Santalales in the clade core eudicots. Prior to the advent of molecular data, the circumscription of the family Olacaceae varied widely between different authorities.[2] Among these various classifications, about 30 genera were included in the family. 15 genera are recognized for Olacaceae by the Germplasm Resources Information Network. The phylogenetic investigation published in 2008 recovered seven clades that were well-supported by molecular and morphological characters, but no formal taxonomic reorganization of the family was proposed. For this reason, Olacaceae in the broad sense was adopted by the APG III-system.[1] The formal reconfiguration of this family (as well as the rest of the order Santalales) was published by Nickrent and co-workers in 2010[3] and this concept is shown below. Olacaceae in the broad sense was split into seven families the genus Schoepfia was placed with Arjona and Quinchamalium (both previously Santalaceae) in the family Schoepfiaceae.

Unplaced genus
  • Brachynema - morphological cladistic analysis places this genus in Ericales,[4] and no genetic study has yet been published
