A few weeks ago I went to the zoo, and in the butterfly farm I found two species that caught my eye. Both are climbing species. The first has purple flowers, and the leaves are similar to Thunbergia alata, but the flower is quite different. The other has strange yellow flowers, with the leaves similar to those of T. grandiflora, which grows in my garden. I hope you can help me with these plants. Thank you.
I've just found that the second plant is a Thunbergia mysorensis... but I still have no idea about the first one.
Thank you very much! I was totally lost, I was looking in the wrong family :P. By the way, reading a little more, I found that it seems Aristolochia sp. have carcinogenic substances! :0 Thank you very much again.
