[3] The flowers of this Thunbergia bicolor are borne in hanging clusters known as axillary pendent racemes.

It consists of a cylindrical or bulging tube that curves, while the corolla limb is oblique in shape.

[3] Stamens, the male reproductive parts of the flower, are present in sets of four and are didynamous, meaning they occur in two pairs of different lengths.

The capsule has a globose shape at the lower part and abruptly narrows into a beak resembling a sword.

[3] Thunbergia bicolor is endemic to Southwest India,[4] where it can be found growing in the South Western Ghats montane rain forests.
