I checked all our observations in efi site. I think keys above are not proper and there is no clear cut demarcation between the two species as pointed out by keys above. Lobes are quite variable with a single post showing one, one and a half lobes. Some are showing more than two lobes and I think it depends on the age of the leaf also. Immature leaves are showing more lobes compared to mature leaves.
I think flora by Dr. Almeida gives *Thunbergia fragrans var. laevis* as a syn. of *Thunbergia fragrans *as per thread: Please identify this climber - 080311NS-8 <https://groups.google.com/group/indiantreepix/browse_thread/thread/54e73798af217e70?hl=en#> Different sources available online, show both the species with contradicting descriptions, as below: An Excursion Flora of Central Tamilnadu, India <https://books.google.co.in/books?id=umMFT6tKtrkC&pg=PA387&dq=Thunbergia+fragrans+%2B+india&hl=en&sa=X&ved=0ahUKEwiLqumChpblAhUJL48KHX3HBSgQ6AEIMjAB#v=onepage&q=Thunbergia%20fragrans%20%2B%20india&f=false> By K.
