Gerrardanthus macrorhizus Description: The Bigfoot, Gerrardanthus macrorrhizus, is a perennial climber, expanded at the base into a succulent pumpkin-like caudex, usually about 30-40 cm in diameter. The smooth, alternate leaves are ivy-shaped, shiny and prominently veined. The Bigfoot has small, dark brownish-yellow orchid-like flowers. There are male and female plants. If a female flowers is fecundated, it is followed by pendulous fruit, which resembles a sea cucumber, and opens at the lower tip to release a number of large, papery, winged seeds. Unlike its close relative Gerrardanthus tomentosus, the leaves and stems are without a covering of downy hairs.
