This species is thought to be distributed throughout Sabah, Malaysia, as well as throughout Brunei. Geographic information with coordinates is lacking for this species, making it difficult to assess to what extent this species is threatened in its habitat. Further research is needed to assess these threats. Since the current population trends of this species cannot be confirmed at this time, this species is listed as DD until further research is carried out.
Why suggested for a Global Red List Assessment?
This species is known from a recording made in Sabah, Malaysia, but is also known to be distributed in Brunei (Eyssartier et al 2009). It has been located within primary forest containing Dipterocarps or Fagaceae (Eyssartier et al 2009). Although this recording has been noted, geographical data is unavailable. A specimen from Malaysia is maintained by the Royal Botanic Garden Edinburgh Herbarium (information provided by gbif, citation needed).
Population and Trends
The exact localities of this species in its natural habitat are unknown. It is likely that this species is threatened by deforestation for palm oil harvesting, however further research is required to confirm this claim. Therefore, current population trends cannot be ascertained at this time.
Population Trend: Uncertain
Habitat and Ecology
This species has been found growing on the soil and sand by rivers, flowing through primary forests containing Dipterocarps or Fagaceae.
Subtropical/Tropical Moist Lowland Forest
This species occurs within Sabah, Malaysia, and Brunei, and is therefore likely at risk as a result of deforestation for the harvesting of palm oil.
Data on the geographic distribution of wild populations of this species is currently deficient. Consequently, population trends cannot be established and so no conservation action can be recommended at this time.
Research into the distribution of this species is required for the accurate assessment of its population trends and consequently its red list categorisation.
