This species is recorded from Bangladesh, India, Myanmar, Yunnan in China and northern Vietnam.

Population
This species is poorly represented in collections (Larsen et al. 1980) and most herbarium specimens found are dated
from the late 19th and early 20th century. This species has been recently reported as new to China (Zhang and Chen
1996) and Thailand (Larsen 1999) and this support the view that it is under recorded.

Definition
Vines, lianas and creepers
Threats
The main threat to this species is the loss of its forest habitat. Forests in Vietnam and the hills of southern Yunnan have
been degraded, cleared and fragmented (Carpenter et al. 2001). Much of the Brahmaputra valley semi-evergreen
forests has been cleared but some large blocks of habitat remain (Rawat 2001). The Mizoram-Manipur-Kachin rain forests has
large areas still intact (Wikramanayake and Tin Than 2001). The main threats are from logging and clearing for agriculture,
particularly shifting cultivation.

Conservation Measures
There are no specific conservation measures in place for this species. It was not found in available lists of seed bank and
botanic garden species. It is reported from the Mahananda Wildlife Sanctuary in West bengal but most records fall outside
existing protected areas. Further research is needed to establish its current georaphic range as this species appears to be
under-recorded. Also more information is needed in relation to the current population status and trends and the specific
habitat status and threats.

Red List Assessment: (using 2001 IUCN system) Least Concern (LC)
Red List Criteria:

Is the species Possibly Extinct? Possibly Extinct Candidate?
Rationale for the Red List Assessment
The extent of occurrence (EOO) exceeds the critical threshold for a threatened category. The estimated area of
occurrence (AOO) and inferred population also exceed the thresholds. It is assessed as Least concern (LC). However, the
habitat of this species has threats and further research is needed to establish the current population status and trends. Also
surveys are needed to confirm the current geographic range, as this species appears to be under-represented in collections.
