Conservation
The collections seen suggest that the extent of occurrence of the species is less than 20,000 km2, suggesting a possible rating of vulnerable, if the habitats are threatened. No recent collections have been seen, but they may well exist in regional herbaria. We consider this species as Data Deficient.
Distribution
Nepal, India (Sikkim, Assam), Bhutan.
Ecology
In dry open places in subtropical areas; alt. 150 – 900 m. Flowering October – November, fruiting November – December.
