Vigna dalzelliana LC Taxonomic Authority: (Kuntze) Verdc. Global Assessment Regional Region: Global Endemic to region Synonyms No common names available Phaseolus dalzellianus Kuntze Phaseolus dalzellii T.Cooke Phaseolus Dalzell 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 The species is reported from Thailand, Cambodia, Laos, Vietnam, the Philippines, India and Pakistan. It is also noted from Sri lanka (Tomooka et al. 2002). Range Size Elevation Biogeographic Realm Area of Occupancy: Upper limit: 2500 Afrotropical Extent of Occurrence: Lower limit: 50 Antarctic Map Status: Depth Australasian Upper limit: Neotropical Lower limit: Oceanian Depth Zones Palearctic Shallow photic Bathyl Hadal Indomalayan Photic Abyssal Nearctic Population There was no population data available but, the population is inferred to be large as it has a wide geographical distribution and occurs in forest over a large altitudinal range. Total Population Size Minimum Population Size: Maximum Population Size: Habitat and Ecology This creeping herb forms a component of the ground flora of monsoon forest. It can root from stem nodes (Tomooka et al. 2002). This species is considered to be a crop wild relative of green gram (Vigna radiata) and black gram (Vigna mungo) (Department of Agriculture, Sri lanka 2006). It is also found mountain grassland. 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 Annual An annual plant, also termed a Therophyte Forb or Herb Biennial or perennial herbacaeous plant, also termed a Hemicryptophyte Vines Vines, lianas and creepers Threats The forest habitat of this species suffers from the general threats of loss and degradation as a result of expanding human populations, particularly conversion for agricultural purposes. Past Present Future 1 Habitat Loss/Degradation (human induced) 1.1 Agriculture Conservation Measures This species is listed as present in the Sanjay Gandhi National Park in India and several national parks in Thailand, for example, the Doi Suthep National Park. It is also recorded as a species of the national gene bank in New Delhi.

Food - human 16. Other 2. Food - animal The seeds are used as a food in the same way as green gram (Vigna radiata (L.) Wilczek). The whole plant is used as fodder and is excellent for soil conservation (Jansen 1989) 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 inferred population also exceed the thresholds. It is assessed as Least Concern (LC). Reason(s) for Change in Red List Category from the Previous Assessment: Genuine Change Nongenuine Change No Change Genuine (recent) New information Taxonom Same category Genuine (since first assessment) Knowledge of Criteria Criteria and criteria Incorrect data used Other Same category but previously change in criteria Current Population Trend: Stable Date of Assessment: 24/08/2010 Name(s) of the H.Chadburn Evaluator(s): Notes: % population decline in the past: % 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 Number of Mature Individuals: Bibliography Ali, S.I., 1977, Papilionaceae, Flora of West Pakistan, , , Department of Agriculture, Sri lanka, 2006, Crop Wild Relatives in Sri Lanka, Crop Wild Relative Species, , , Jansen, P.C.M, 1989, Vigna dalzelliana (O.
