Hibbertia platyphylla is a species of flowering plant in the family Dilleniaceae and is endemic to south-eastern South Australia. It is a shrub with linear stem leaves and yellow flowers arranged singly in leaf axils with ten to fifteen stamens arranged on one side of two carpels. Description. "Hibbertia platyphylla" is a shrub that typically grows to a height of and has hairy foliage. The leaves are usually linear, long, wide on a petiole long. The flowers are arranged on the ends of branches with linear to elliptic bracts long at the base. The five sepals are  joined at the base, the outer sepal lobes long, wide and the inner sepal lobes long, wide. The five petals are yellow, broadly egg-shaped to heart-shaped, with the narrower end towards the base, long and there are ten to fifteen stamens fused at the base on one side of the two carpels, each carpel usually with six ovules. Taxonomy. "Hibbertia platyphylla" was first formally described in 2010 by Hellmut R. Toelken in the "Journal of the Adelaide Botanic Gardens" from specimens he collected near the Foul Bay Road in 1994. The specific epithet ("platyphylla") means "broad- or flat -leaved". In the same journal, Toelken changed the name of "Hibbertia sericea" var. "major" of John McConnell Black to "Hibbertia platyphylla" subsp. "major" and described two new subspecies, the three new names now accepted by the Australian Plant Census: Distribution and habitat. Subspecies "halmaturorum" usually grows in mallee and mainly occurs in the western parts of Kangaroo Island. Subspecies "major" often grows on rocky slopes in woodland on the south-east coast of South Australia but also on the Eyre Peninsula and scattered parts of the central Yorke Peninsula. Subspecies "platyphylla" often grows near surface limestone and is found on  the coast, southern Yorke Peninsula and south-eastern Eyre Peninsula.
