22092017BHAR – Critically Endangered species needs confirmation : 7 posts by 3 authors. Attachments (1) – 5 MB

Bought this sapling from Auroville Botanical garden.
Need confirmation for below species:

It is not possible to tell this apart from Thespesia populnea or any other taxon with similar kind of leaves, based on this single vegetative image only.
Only flowering/fruiting specimens can suggest anything conclusive..

Thank you very much for your reply.
You are correct. Even I thought of Thespesia populnea.
Another problem here: it is endemic to particular region only. So, many people are not aware of it.
I will try my level best in identifying through leaves.

Was this name (Hildegardia populifolia) mentioned by them ?

Yes. The name was given by them only. I got the details how to differentiate it: The stem will be in more green color than that of Thespesia populnea.
