Location- Chinnar

Habitat-   Wild

Plant Habit – Epiphytic herb


Note : This is a species mentioned in the Plant list as a synonym of Luisia tenuifolia Blume which I strongly feel is not correct. The Habitat and the Habit and the shape of the flower and its appearance are entirely different

Your plant is Luisia birchea and the second plant I think is Luisia evangelinae.

Thank you very much .. I have no doubt in their id’s. I have only on doubt why that “Plant list” has made them the same species ?
Thanks to … for their comments. Still I am not fully placed how to go about replying to each person who had made comments.

The Name L.evangelinae is now the synonym of L.tenuifolia.
