Androcalva pearnii is a suckering shrub that typically grows to high and wide, its new growth covered with fine, star-shaped hairs. The leaves are oblong to elliptic, long and wide on a
petiole long with narrowly triangular
stipules long at the base. The edges of the leaves are wavy with 5 to 7 pairs of rounded lobes long and both surfaces of the leaves are covered with velvety hairs. The flowers are arranged in groups of 3 to 8 on a
peduncle long, each flower on a
pedicel long, with
bracts long at the base. The flowers are white and cream-coloured to pale green and in diameter with 5 petal-like
sepals, the lobes long and wide. The petals are white, long, and there are 3
staminodes between each pair of
stamens. Flowering occurs from September to December and in March. ==Taxonomy==
