Petrocosmea pubescens
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Petrocosmea pubescens faces significant pressure from habitat degradation in its restricted limestone karst environments across southwestern China. The species' specialized requirements for humid rock crevices and cave entrances make it particularly vulnerable to quarrying activities and tourism development in karst regions. Agricultural expansion and infrastructure development continue to fragment its already limited habitat, while collection pressure for the horticultural trade poses an additional threat to wild populations.
Habitat
This species inhabits humid limestone rock crevices, cave entrances, and shaded cliff faces in karst landscapes of southwestern China. It requires consistently moist conditions and grows primarily on moss-covered limestone surfaces in areas with high humidity and filtered light.
