Myoporum cordifolium, commonly known as Jerramungup myoporum, is a plant in the figwort family, Scrophulariaceae. It is a shrub with thin, stiff branches and tiny, heart-shaped leaves, both covered with wart-like tubercles. Single white flowers with purple spots develop in the leaf axils and are followed by wrinkled green or brown fruits. It is endemic to a small area in the south-west of Western Australia

Taxonomy and naming
Myoporum cordifolium was first formally described in 1859 by Ferdinand von Mueller in Fragmenta phytographiae Australiae and given the name Disoon cordifolius.[3][4] In 1917, George Claridge Druce transferred it to the present genus.[5] The specific epithet (cordifolium) is from the Latin cor (hence cordis) meaning "heart"[6] and folium meaning "a leaf"[7] referring to the heart-shaped leaves.[1]
Distribution and habitat
Myoporum cordifolium occurs between the Ongerup and Jerramungup districts in the Esperance Plains, Jarrah Forest and Mallee biogeographic regions,[8] where it grows in sandy or clay loam.[9]
Conservation
Myoporum cordifolium is classified as "Threatened" by the Western Australian Government Department of Parks and Wildlife[8] meaning that it is likely to become extinct or rare and therefore in need of special protection.[10] It has also been declared "vulnerable" by the Australian Government Department of the Environment.[11]
