This species was initially described as growing in Sarawak, Peninsular Malaysia (Cesati and Beccari 1879). Any further information regarding this species distribution, habitat preferences, or potential threats is lacking, although if any wild populations of this species do exist within its known locality, they would likely be threatened by deforestation for palm oil harvesting. Further information is required in order to assess the current status of any existing wild populations of this species, and so until research is carried out to gather this information, this species is listed as DD.
Why suggested for a Global Red List Assessment?
The type of this species was originally found in Sarawak, Malaysia (Cesati and Beccari 1879).
Population and Trends
The current status of the wild populations of this species is difficult to determine without further research, although this species could be under threat, and therefore show a decreasing population size. Further research is needed to affirm this claim, and so this species’ population trends remain uncertain.
Population Trend: Uncertain
Habitat and Ecology
The original text for this species is not in English, but appears to describe this species as growing spread on the lower faces of the leathery leaves of a certain plant. This passage could also possibly be referring to Kokoona coriacea, a species of plant occurring in Sarawak.
Subtropical/Tropical Moist Lowland Forest
This species appears to exist within Peninsular Malaysian forest, meaning that it is likely threatened by deforestation for palm oil harvesting, should any populations remain at this locality. Furthermore, Kokoona coriacea, with which this species is thought to possibly associate with, is itself threatened by such deforestation, as well as by disturbance for housing and urban areas.
The only known wild population of this species is thought to exist within threatened habitat. Protection of this species’ habitat is needed.
Resource & habitat protection
Further research is needed to determine the extent to which this species is threatened within its natural habitat, where this species occurs within Sarawak, and in order to determine whether this species does indeed associate with Kokoona coriacea.
