The alternately arranged leaves are on stalks to 6 cm long.
There are axillary tendrils up to 15 cm long.
Leaves can be up to 10 cm long and wide.
The blade can be entire but is usually divided half way to the midrib into 3 (5) lobes.

There are gland-tipped hairs on the stipule filaments, the leaf blade edges and the bracts.
The sticky exudate, with digestive enzymes, traps small insects.
