Aextoxicon
genus of plants
Aextoxicon is a genus of dioecious trees native to southern Chile and Argentina. It is the only genus in the monotypic family Aextoxicaceae, and is itself represented by the olivillo (Aextoxicon punctatum). It is a large evergreen tree native to the forests of the Valdivian temperate rain forests and Magellanic subpolar forests of the Pacific coast of southern Chile, where it forms is a canopy tree in the broadleaf forests. It can reach 15 m tall.
The APG system (1998) and the APG II system (2003) left the family Aextoxicaceae unplaced in the core eudicots. It has since been included in the order Berberidopsidales. The genus was formerly often included in the family Euphorbiaceae.
Description
Aextoxicon punctatum is a large tree often found in the canopy or emergent. It has opposite leaves with dark green coloration on the top and lighter green below, and is covered in rusty peltate scales. The flowers are actinomorphic and unisexual, in hanging racemes.
This brief starts where responsible research should: with the source description of “Aextoxicon” as genus of plants. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as genus of plants. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 9, 2026. The linked authority identifier is Q1070232. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1998 and 2003.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
