This species is heavily lacking in geographic information, as well as information regarding its habitat preferences and potential threats, which can only be inferred at this time. Data regarding the trends of any wild populations of this species are lacking, although this species is known to exist under preservation as 3 separate specimens. This species is therefore listed as DD in terms of provenance until further research into this species is performed.
Why suggested for a Global Red List Assessment?
This species is known to occupy the Malaysian state of Sabah, in Northern Borneo (Nova Hedwigia 1970). No occurrences of this species are known with geographic coordinates, however 3 specimens exist, recorded in Indonesia, maintained by the Royal Botanic Garden Edinburgh Herbarium (information provided by gbif, citation needed).
Population and Trends
No data of occurrences outside of Herbarium specimens is currently known, and so it is currently not possible to establish the current population trends of this species.
Population Trend: Uncertain
Habitat and Ecology
Although no accurate geographical information is available for the specimen, its initial description was made in Saban, Northern Borneo, and so it is likely that this species grows within subtropical or tropical rainforest biomes.
Subtropical/Tropical Moist Lowland Forest
This species exists within Malaysia, and is therefore likely to be threatened by the deforestation required for oil palm plantations.
The exact locality, habitat preference, and population data relating to this species is poorly understood. No conservation action can be recommended at this time.
Much research into the population trends, habitat preferences, and threats which may be affecting this species in the wild is required for accurate assessment of the risk of extinction of this species.
