It is also reported from North-East India but no specimens, or listing in the Floras, were found, and its presence there remains uncertain. Range Size Elevation Biogeographic Realm Area of Occupancy: Upper limit: 1600 Afrotropical Extent of Occurrence: Lower limit: 600 Antarctic Map Status: Depth Australasian Upper limit: Neotropical Lower limit: Oceanian Depth Zones Palearctic Shallow photic Bathyl Hadal Indomalayan Photic Abyssal Nearctic Population No data was available about the current population status and trends. The most recent collection was in 2005 from Yunnan, other records are much older. Total Population Size Minimum Population Size: Maximum Population Size: Habitat and Ecology This climbing shrub or liana is found in forests on lower mountain slopes. 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 Shrub - size Perennial shrub (any size), also termed a Phanerophyte if >1m or a Chamaephyte if <1m Vines Vines, lianas and creepers Threats The forest habitat of this species faces threats, mainly from conversion for agricultural purposes. For example the tropical seasonal rainforest in southern Yunnan decreased from a cover of 10.9% of the total area of the region in 1976 down to 3.6% in 2003, mainly due to rubber planting (Zhu 2008). Past Present Future 1 Habitat Loss/Degradation (human induced) 1.1 Agriculture 1.3 Extraction 1.3.3 Wood 1.4 Infrastructure development Conservation Measures No specific conservation measures are in place for this species. It was not found in available lists of seed bank or botanic garden species. Further research is needed to establish its habitat status and threats to determine its conservation needs. Surveys are recommended to confirm its current geographical range and population status, as many herbarium specimen records are old. It is likely to benefit from the identification of new, and expansion of existing protected areas. It has been recorded in the Ba Vi area in Vietnam, and the Doi Inthanon area in Thailand, both of which have National Parks.

Unknown 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 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 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 population are also inferred to exceed the thresholds. It is assessed as Least Concern (LC). However, the forest habitat of this species faces ongoing threats, and research is needed to establish and monitor the current population and habitat status and to confirm the current geographical range.
