Red List Category & Criteria: Data Deficient ver 3.1

Year Published: 2011

Date Assessed: July 12, 2011

Justification: The species is recorded from separate locations in northern India (Meghalaya, Assam, and Orissa), southern India (Kerela), from a single recent record in eastern Bangladesh, and from Myanmar. Little is known of the species current full distribution and population trends, and even within that area appears to be relatively little known. Available information is inadequate to provide an informed assessment of its conservation status and so it is classed as Data Deficient. Geographic Range

Range Description: The species is recorded from northern India (Khasia Hills and Garo Hills (Meghalaya, Assam, and Orissa (Sambalpur)), Bangladesh (Chittagong) (Bhatti and Ingrouille 2007) from Myanmar, and also from southern India (Kerala (Malabar, Godavari District). In eastern Bangladesh it grows on sandy soils (Khanam et al. 2003, Bhatti and Ingrouille 2007).

Country Occurrence: Native: Bangladesh; India (Assam, Kerala, Meghalaya, Orissa); Myanmar (Myanmar (mainland))
