Leaves glabrous; blade orbicular, variable in size, ± 30-150 mm in diameter, margins entire or shallowly lobed, upper surface green, prominently veined, lower surface paler; petioles up to 300 mm long. Flowers: solitary on long pedicels; corolla 25-60 mm in diameter, dark orange, shades of red and yellow or yellow with red markings; Oct.-Apr. Fruit of 3 mericarps; seeds elongate, 10-15 mm long.
A creeping climbing annual herb. It grows to 60-300 cm high and can spread to several m wide with long branches. The leaves are small and round. They are light green. Leaves are 2.5-6 cm across. The edges of the leaves are wavy. The veins radiate out from the centre. It has trumpet like flowers. The flowers are orange and yellow and have a pointy piece at the back of the flower.
