Plants in the genus Androcalva are shrubs or trees and have stems, leaves and flowers covered with star-like hairs. The leaves are simple, often with irregularly-toothed or lobed edges, and with ligules at the base but that are sometimes deciduous. The flowers are bisexual, arranged in cymes opposite leaf axils, with 5 sepals, 5 petals, 5 stamens, and 5 staminodes sometimes with 3 lobes. The fruit is a bristly capsule with five valves, and is covered with star-shaped hairs.[1] [2] [3]
