This Tabernaemontana sp. has been introduced to Thailand a few years ago. The flower is big and very fragrant. I'm trying to figure out if it is T. africana or T. pachysiphon. The information I got from the internet is somewhat confusing. Can anybody identify the species of this Tabernaemontana? Thank you very much.
Flora Zambesiaca has an excellent description of Tabernaemontana pachysiphon, so I would rely on that as a species description. However, I haven't been able to find a key that distinguishes the two species (are you positive it is one of the two? there are over a hundred species...)
