Indeed .., Yellow eyed Susan Vine
its actually called BLACK eyed susan VINE… ( AND A FEW OTHER FLOWERS ARE ALSO CALLED BLACK EYED SUSAN FLOWERS .. a daisy with black center comes to mind: Rudbeckia hirta… considered a weed in most NE states…it came east along with seeds for clover from the western US states… but that’s another story… )
I am not sure if I have heard the name Yellow eyed susan..
Acanthaceae Week: Thunbergia alata from California: Thunbergia alata Bojer ex Sims, Bot. Mag. 52: t. 2591 1825.
syn: Endomelas alata (Bojer ex Sims) Raf.; Thunbergia cordifolia Nees.
Common Name: Black-eyed susan vine
It is interesting to note Thunbergia grandiflora Roxb. is considered as synonym of this species in the Kew Plant List based on TROPICOS source. Interestingly this conclusion is base on a paper Schonenberger, J. 1999. Floral structure, development and diversity in Thunbergia (Acanthaceae). Bot. J. Linn. Soc. 130: 1–36., in which T. erecta is perhaps also considered as synonym of this species, but Plant List treats it as an accepted name.
I request any colleague who has online access to this journal to kindly help in getting this important paper.
Plant was photographed from California in 2010, plant climbing on fence

Attached are pictures of Thunbergia alata captured at Pune in December 2012.
since you took both 16 and 17 serial numbers…
tell me was the color of the flowers really that much faded in 17? compared to 16?
nice pictures but the color sort of looks like a variant if not the problem of the digital color rendering
The flowers in this post were growing wild in a vacant plat adjoining a residential bungalow colony in the heart of Pune and they were captured in the evening…
The flower in my other post was growing wild in Lalbagh, Bengaluru and was clicked early in the morning….therefore they were posted in 2 different posts.
Does the timing affect the colour, does the colour pale/fade towards evening?

Thunbergia alata Bojer ex Sims
yes. an Indian vine appropriated by the tropical nurseries all over the world as their own. grown right it can be prolific
Thanks … I always thought it is an exotic. Most of the sites say that it is native of eastern Africa.
seed packets in usa even forty years ago used to say its Indian. i was not reading botany papers then. last i bought seeds was about ten years ago. have not had the energy recently. now CABI says its a weed of concern worldwide. think of it. even 30-40 years ago a seed packet of 10 seeds used to cost 2 to 3 dollars. because they said it was exotic, from India. now its a weed of concern!!!
yes you are right its native of Africa per CABI
Now , this species is one more example of one popular name applied to more than one plant / flower …
in this case “Black Eyed Susan” is also shared by Rudbeckia hirta.
