An evergreen climber with spreading stems often forming dense masses and attaining up to 12 m high and 20 mm diameter. Bark pale brown, rough, exfoliating in loose fibrous strips. Leaves mostly fascicled on arrested branches, trifoliate. Petiole usually 2.5- 5 cm long, sometimes less. Leaflets variable, 3.8- 12.7 by 0.7- 3 cm, entire or more or less deeply 3-   lobed, sometimes to the base very membranous, usually lanceolate or linear lanceolate, acute, glabrous, glossy beneath. Flowers greenish, on axillary fascicled, slender, drooping peduncles 2.5- 6.3 cm long. Sepals 15- 18 mm long, erect, densely silky-pubescent outside. Filaments glabrous, pink. Anthers lilac.

Its fresh roots are crushed and tightened in a clean cotton cloth and heated over an oven for two minutes. During this process, strong fume is produced, the inhalation of which through nose relieves sinus. (Nepali System).
