Commersonia parviflora, commonly known as small flowered rulingia, is a species of flowering plant in the family Malvaceae and is endemic to the south of Western Australia. It is a low, prostrate or dense shrub with wrinkled, egg-shaped leaves with rounded teeth on the edges, and clusters of small, white flowers.
Commersonia parviflora is a low, prostrate or dense shrub that typically grows to high and wide, its new stems hairy. The leaves are egg-shaped and wrinkled, long and wide on a petiole long with stipules long at the base. The edges of the leaves have irregular, rounded lobes with the edges rolled under, the upper surface has prominent veins and the lower surface is densely covered with star-shaped hairs. The flowers are arranged in clusters of 2 to 11 on a peduncle long, each flower on a pedicel long. The flowers are wide with five white, petal-like sepals that are hairy on the back. The petals have a linear ligule half as long as the sepals, and there is a single hairy staminode between each pair of stamens. Flowering occurs from July to November and the fruit is a hairy capsule in diameter.[1]
This species was first formally described in 1837 by Stephan Endlicher who gave it the name Rulingia parviflora in Enumeratio plantarum quas in Novae Hollandiae ora austro-occidentali ad fluvium Cygnorum et in sinu Regis Georgii collegit Carolus Liber Baro de Hügel from specimens collected from King George Sound by Charles von Hügel.[2] [3] In 1882 Ferdinand von Mueller transferred the species to the genus, Commersonia as C. parviflora.[4] [5]
The specific epithet (parviflora) means "small-flowered".[6]
Commersonia parviflora grows in heath, scrub and woodland between Darkan, Albany and Esperance in the Esperance Plains, Jarrah Forest, Mallee and Warren bioregions of southern Western Australia.
