Common names: Blue trumpet vine, Bengal clock vine, sky vine. The plant though closely related to T. laurifolia is treated as synonym of T. alata in Kew Plant List and perhaps in Schonenberger, J. 1999.

Attached images are unknown species. Please ID the sp. I am inclined more towards Thunbergia sp. Yes, the fruits suggest Thunbergia. Thanks, … I think close to images of Thunbergia grandiflora Roxb.

Looks like some Thunbergia sp. (Acanthaceae). I guess it could be Thunbergia grandiflora (Roxb. ex Rottl.) Roxb. (accepted name) Habitat
T. grandiflora can be found growing in moist areas from sea level to middle elevations. It is especially common in disturbed areas, urban forests near human settlements, riparian forests, forest gaps, forest edges and along roadsides (ISGG, 2012; PIER, 2012). In Australia, this species has been reported growing in areas from sea level to 750 metres in riparian areas, rainforest margins, roadsides, disturbed sites and old gardens (Queensland Department of Primary Industries and Fisheries, 2007). In Hawaii, T. grandiflora grows in lowland moist areas, disturbed forests, and urban areas (Starr et al., 2003). Please validate. I also feel it is closer to images at Thunbergia grandiflora Roxb. as per comparative images at Thunbergia Nepali Names : काग चुच्चे Kaagchuchche / काग फुली Kagphulee

I also think so. Pl. check comparative images at genera page in efi site. Pl. check comparative images at /species/a—l/a/acanthaceae/thunbergia
Closest I find is /species/a—l/a/acanthaceae/thunbergia/thunbergia grandiflora as per comparative images. KEW says Thunbergia grandiflora Roxb. is a synonym of Thunbergia alata Bojer ex Sims. But ‘google search’ gives all yellow flowers for Thunbergia alata Bojer ex Sims !

I hope new comers will learn from your posts. How to do homework before posting it on Eflora. yes … grows at the hort and elliot park on chowringhee and many places in and around the canals in shyambazar etc… saw them during the whirlwind durgapuja pandal hopping a couple of years ago…. I said yes to the plant being T. grandiflora without reading your first line about KEW The Plant List listing.
Having gone through the Plant List, with so many missing names, unresolved names, and many wrong synonymy records, I have become increasingly unsure about The Plant List.
I prefer to follow GRIN for records which are dealt there and periodically updated by its scientists. GRIN as well as several recent treatments recognise T. grandiflora. as distinct species.
Yes … is right, T. alata is a sufficiently distinct from T. grandiflora, and to call T. grandiflora its synonym at least I find hard to digest.
If there is any species closest and can be combined with is T. laurifolia. The two are very close.

In the attached collage the background colour is taken from the colour of the flower itself. With careful observation you will find two small spots in the flower. You got it, the background is composed of this colour.
