Calanthe delavayi

Unknown

Overview

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

Calanthe delavayi faces severe pressure from habitat destruction as montane forests across its range are cleared for agriculture and development. Collection for traditional medicine and the ornamental plant trade has significantly reduced wild populations, particularly targeting the species' distinctive pseudobulbs. Climate change poses an additional threat by altering the cool, humid conditions this orchid requires in its high-altitude forest habitats.
