Conservation
One recent collection has been seen, although more may well exist in regional herbaria. Henry et al. (1987), in Flora of Tamil Nadu ser. I: Analysis Vol. 2, record this species as rare. Manickam et al. (2003), in Checklist of the Flora of Tirunelveli Hills, suggest a small extent of occurrence for this species. An assessment of threatened plants of the Keral Forest (www.keralaforest.org) cites this species as endangered.
