Heptapleurum marlipoense

Unknown

Overview

Heptapleurum marlipoense is a species of plant in the family Araliaceae. It is a tree endemic to southeastern Yunnan in China. It is assessed as Critically Endangered.

Heptapleurum marlipoense faces severe threats from limestone quarrying and mining activities that directly destroy its specialized karst habitat. The species' extremely restricted range in Guangxi Province, China, makes it particularly vulnerable to habitat fragmentation and local extinction from industrial development. Agricultural expansion and infrastructure development in the surrounding lowlands further isolate remaining populations.
