It is a climbing, fibrous-rooted perennial with stems usually having adventitious roots. Its lamina leaves that are triangular-cordate or triangular-hastate, 1–3.5 cm in length and 8–30 mm wide. The apex is acute to attenuate. Basal lobes are acute or undiscerning, with some margins, and small teeth towards the base. It is palmately veined and has a petiole that is 1–1.5 cm long.[3]

Peduncles are 2–5 cm long. Sepals are long and simple, which are 10–15 mm long in flower and 20 mm long in fruit. Corolla is 3–4.5 cm long, purple in colour, and is lighter near the base. The lobes are shorter than the tube.[4]
