Guichenotia seorsiflora is a species of flowering plant in the family Malvaceae and is endemic to the south-west of Western Australia. It is a low, spreading, multi-stemmed shrub with linear to narrowly egg-shaped leaves and white flowers arranged singly in upper leaf axils.
Guichenotia seorsiflora is a spreading, multistemmed shrub that typically grows to high and wide, its new growth covered with white, star-shaped hairs. Its leaves are linear to narrowly egg-shaped, long and wide on a petiole long with linear to narrowly egg-shaped stipules two-thirds as long as the leaves, at the base. The edges of the leaves are rolled under, and the upper surface is covered with white, star-shaped hairs. The flowers are arranged singly in upper leaf axils with a bract long at the base, the pedicel long, with a bracteoles long at the base, on a peduncle long. The petal-like sepals are pink in the bud stage, later white, joined at the base and covered with white, star-shaped hairs. There are tiny, dark red petals but no staminodes. Flowering occurs from July to September.[1]
Guichenotia seorsiflora was first formally described in 2003 by Carolyn F. Wilkins and the description was published in Australian Systematic Botany.[2] The specific epithet (seorsiflora) means "separate-flowered", referring to the flowers arranged singly.[3]
This species of guichenotia usually grows on breakaways in heath and open woodland in scattered locations near Youndegin, Corrigin and Kellerberrin in the Avon Wheatbelt bioregion in the south-west of Western Australia.[1]
Guichenotia seorsiflora is listed as "Threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions, meaning that it is in danger of extinction.[4]
