An evergreen shrub or small tree. It grows to 4-10 m high and spreads to 2 m across. The stem is erect and slender. The branches are crooked. The leaves are green and have 2 lobes which divide the leaves for half their length. They are rounded and 7-16 cm long and the same width. The leaf stalk is 3 cm long. The flowers are purple and orchid like. They are large and can be 6 cm across. They can occur either on their own or in flowering branches and can be in the axils of leaves or at the ends of branches. The flower buds are 4-5 angled. The flower petals are reddish purple and often with coloured marks. The petals do not overlap and there are 3-4 stamens. The fruit are oblong brown pods. They are flattened and can be 25 cm long by 2 cm wide. There are 5-6 seeds. The seeds are 12-13 mm long.
Introduced, unarmed, ornamental shrub, branchlets glabrous to lightly pubes-cent. Leaves broadly orbicular, cordate to truncate basally, usually prominently 9-veined, glabrous to lightly pubescent below, up to 13 cm. long and 16 cm. broad, shallowly cleft apically, lobes obtuse, rounded; petiole angled, callous-swollen apically and basally, up to 4 cm. long. Inflorescence terminal or subterminal,
several-to many-flowered. Flowers conspicuous, 3-4 cm. long; calyx scarcely spathaceous, tube up to 1 cm. long, limb up to 2.5 cm. long; petals clawed, spatulate-obovate, about 3.5 cm. long; fertile stamens 3, glabrous; anthers linear-oblong, versatile, 7 mm. long in bud; ovary long-stipitate, densely pubescent, with a truncate stigma.
