Description

Native perennial, trailing or climbing with tendrils.

Leaves are alternate, palmately lobed, rough and hairy, and cordate at the base.

Flowers are unisexual, corolla campanulate and white, monoecious.

The bladder-like fruits are sparsely to densely covered with flexible prickles that harden with age, dehiscent at apex when dry. [1]
