Upper Level Taxonomy Kingdom: PLANTAE Phylum: TRACHEOPHYTA Class: MAGNOLIOPSIDA Order: FABALES Family: LEGUMINOSAE Lower Level Taxonomy Rank: Infra- rank name: Plant Hybrid Subpopulation: Authority: General Information Distribution This species is found in Peninsular Malaysia, Singapore, Sabah, Kalimatan, Jawa, Sumatera, Sulawesi, Thailand and the Philippines. Range Size Elevation Biogeographic Realm Area of Occupancy: Upper limit: 800 Afrotropical Extent of Occurrence: Lower limit: 0 Antarctic Map Status: Depth Australasian Upper limit: Neotropical Lower limit: Oceanian Depth Zones Palearctic Shallow photic Bathyl Hadal Indomalayan Photic Abyssal Nearctic Population No population data is availbale for this species. Many of the herbarium records found are from the late nineteenth and early twentieth century. The most recent collections found were from Singapore in 2004. Whitmore (1972) reported this species to be rare in Peninsular Malaysia, with records of it being collected only once, at three separate locations. Total Population Size Minimum Population Size: Maximum Population Size: Habitat and Ecology This tree is found in lowland forest. System Movement pattern Crop Wild Relative System Movement pattern Crop Wild Relative Terrestrial Freshwater Nomadic Congregatory/Dispersive Is the species a wild relative of a crop? Marine Migratory Altitudinally migrant Growth From Definition Tree - size unknow Tree (any size), also termed a Phanerophyte (>1m) Threats This species suffers from the general threats of habitat loss associated with expanding human populations. Its lowland forest habitat is vulnerable to clearance for agriculture, including palm oil plantations, timber extraction and infrastructure developments. In Singapore, for example, extensive urbanization has lead to the species here being considered as Critically Endangered (Chong et al. 2009). Past Present Future 1 Habitat Loss/Degradation (human induced) 1.1 Agriculture 1.1.1 Crops 1.1.1.1 Shifting Agriculture 1.1.1.2 Small-holder farming 1.1.3 Non-timber plantations 1.1.3.2 Large-scale 1.3 Extraction 1.3.3 Wood 1.3.3.1 Small-scale subsistence 1.3.3.3 Clear-cutting 1.4 Infrastructure development 1.4.2 Human settlement Conservation Measures There are no specific conservation measures in place for this species. It may benefit from existing protected areas, for example, it is recorded from the Sungai Wain Protected Area, in Kalimantan Timur. However, such areas cover only a small proportion of its range. Further research is needed into its current population status and trends, and its habitat status and threats, to help determine any specific conservation needs. It was not found in available lists of seed bank or botanic garden species.

Construction/structural materials Trend in the level of wild offtake/harvest in relation to total wild population numbers over the last five years: Trend in the amount of offtake/harvest produced through domestication/cultivation over the last five years: CITES status: Not listed IUCN Red Listing Red List Assessment: (using 2001 IUCN system) Least Concern (LC) Red List Criteria: Date Last Seen (only for EX, EW or Possibly EX species): Is the species Possibly Extinct? Possibly Extinct Candidate? Rationale for the Red List Assessment The extent of occurrence (EOO) for this species exceeds the critical threshold. The estimated area of occupancy (AOO) and inferred population also exceed the thresholds. It is assessed as Least concern (LC). However, surveys are recommended to establish the current gepgraphical distribution and habitat status as many of the herbarium records found are from the late nineteenth and early twentieth century. Also research is needed to establish the current population status and trends, as this species is known to be rare in some parts of its range.
