Drosera androsacea is a pygmy species native to the inland south west of Western Australia. It actively grows during winter, before forming a pentagonal stack of stipular buds as the weather warms up. The flowers emerge in spring and are borne on a moderately glandular and variably hirsute scape. The flowers are white to light pink with the undersides of the petal sometimes striped with darker pink. The sepals are obovate, with a slightly serrated edge. After flowering, the species enters dormancy over summer.
