The leaves are opposite and simple being 6 to 10 cm across, with base truncate or cordate. The leaves are 5-lobed and palmate. The lobes are ovate, the middle lobe having 5 to 8 pairs of lateral veins with minor veins finely reticulate.[4]

Flowers are whitish with five purplish sepal . They have five white petals and eight stamen that are longer than the petals.[4]

The fruit are glabrous ranging from 2.5 to 3 cm long that spread at a wide angle.[4]
