Phialanthus macrostemon
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Phialanthus macrostemon faces significant pressure from deforestation and habitat conversion throughout its limited range in tropical montane forests. Agricultural expansion and logging activities have fragmented its specialized cloud forest habitat, while climate change threatens to shift the narrow altitudinal zones where this species can survive. The species' restricted distribution makes it particularly vulnerable to localized habitat destruction.
Habitat
Phialanthus macrostemon inhabits tropical montane cloud forests at elevations between 1,200-2,400 meters, typically in areas with persistent fog and high humidity. The species requires the specialized microclimate conditions found in these cloud forest ecosystems, often growing in association with epiphytic communities on steep mountain slopes.
