Primulina modesta

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Primulina modesta faces severe threats from limestone quarrying activities that directly destroy its specialized karst habitat in Guangxi Province, China. The species' extremely restricted range makes it particularly vulnerable to habitat fragmentation, while agricultural expansion and infrastructure development continue to encroach upon remaining limestone cliff environments where this endemic gesneriad survives.

Threat summary

Habitat

Primulina modesta is endemic to limestone cliffs and karst cave entrances in the subtropical regions of Guangxi Province, China. This specialized gesneriad grows in shaded, humid microhabitats on vertical limestone surfaces and rocky crevices where moisture levels remain consistently high.
