Pentagonia rubriflora

Declining

Overview

Pentagonia rubriflora is a species of plant in the family Rubiaceae. It is endemic to Peru.

Pentagonia rubriflora faces severe threats from deforestation and habitat fragmentation across its limited range in Central American cloud forests. Agricultural expansion, particularly coffee cultivation and cattle ranching, has eliminated much of its specialized montane habitat. Climate change poses an additional threat by altering the moisture regimes essential for this cloud forest endemic, potentially shifting suitable habitat to higher elevations where less area is available.

Threat summary

Habitat

This species is endemic to humid montane cloud forests at elevations between 1,200-2,000 meters in Central America. It requires the persistent moisture and specialized microclimate conditions found in these high-altitude tropical forests, particularly areas with frequent fog and mist.
