Botanic information
Leaf: The sessile leaves are broadly ovate to rhombic-ovate up to 200mm (7¾ in) wide with an acuminate apex. The bright green leaves have prominent veins but no pigmentation and 3-leaves are arranged in a terminal whorl on a slender stem.

Flower: The funnelform flowers have 3-green sepals, 3-spreading pointed petals and a purplish ovary. The petals are colours brownish-purple or occasionally white, yellow or green. The flowers are held above the foliage on a greenish scape accompanied with bracts and appear during mid-spring. The  fragrance resembles rotting meat, which encourages flies to pollinate them.

Fruit: The small fleshy dark maroon globose berry has 3-chambers and produces a slight fragrance. The small seeds are viable but the plant is commonly reproduced vegetatively.
