Threats [top]
Major Threat(s): The forest habitat of this species has declined in both extent and quality. This is largely as a result of pressures from expanding human populations, with conversion for agricultural purposes and logging and also infrastructure developments. For example, it is now reported as extinct in Singapore. This species was also previously recorded from Johor and Penang, and extensive collections, since 2006, for the Flora of Peninsular Malaysia Project, have not encountered this species (Chung 2011).
