The most recent herbarium record is dated 1993. Total Population Size Minimum Population Size: Maximum Population Size: Habitat and Ecology This species is found in a variety of forest types and disturbed vegetation. It occurs in seasonal rain forests, often by streams, dry evergreen forests, primary and slightly disturbed evergreen hardwood forests, swamp forests, degraded caducous forests aswell as bam•boo, scrub and roadsides. 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 Forb or Herb Biennial or perennial herbacaeous plant, also termed a Hemicryptophyte Shrub - size unkno Perennial shrub (any size), also termed a Phanerophyte if >1m or a Chamaephyte if <1m Vines Vines, lianas and creepers Threats This species occurs in a variety of habitats and may tolerate some disturbance. It suffers from the general threats of human induced habitat loss and degradation. Past Present Future 1 Habitat Loss/Degradation (human induced) Conservation Measures This species has been recorded from Cat Tien National Park in Vietnam. It is also recorded from Xishuangbanna Tropical Botanical Garden, Yunnan, China. It was not found in available lists of seed bank species. In view of some past difficulties with separation of this species from M.interrupta further taxonomic research is recommended.

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 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 for a threatened category. The estimated area of occupancy (AOO) and inferred population also exceed the thresholds. It is found in a variety of habitats and may tolerate some disturbance. It is assessed as Least concern (LC). However, further research is needed to establish the current population status and trends. Reason(s) for Change in Red List Category from the Previous Assessment: Genuine Change Nongenuine Change No Change Genuine (recent) New information Taxonomy Same category Genuine (since first assessment) Knowledge of Criteria Criteria Revisio and criteria Incorrect data used Other Same category but previously change in criteria Current Population Trend: Unknown Date of Assessment: 23/08/2010 Name(s) of the Assessor(s): H.Chadburn Evaluator(s): Notes: % population decline in the past: Time period over which the past decline has been measured for applying Criterion A or C1 (in years or generations): Time period over which the past decline has been measured for applying Criterion A or C1 (in years or generations): % population decline in the future: Time period over which the future decline has been measured for applying Criterion A or C1 (in years or generations): Number of Locations: Severely Fragmented: Number of Mature Individuals: Bibliography Wilmot-Dear,C.M., 1992, Kew Bull.47:203-245.
