Overview

Psychotria tubuaiensis is a species of plant in the family Rubiaceae. It is endemic to the Tubuai Islands of French Polynesia.

Psychotria tubuaiensis faces severe threats from habitat destruction on its limited range in the Austral Islands of French Polynesia. The species is particularly vulnerable to invasive plant species that alter native forest composition and compete for resources. Human development pressures and potential climate change impacts on its restricted island habitat further compound the risks to this endemic coffee family plant.
