Lasiopetalum baueri, commonly known as slender velvet bush, is a common shrub of the mallow family. It was first described by Joachim Steetz in 1806. It was named for the 19th century botanical artist Ferdinand Bauer. It is found in southern South Australia, central and western Victoria, southwestern New South Wales, where it is confined to the vicinity of Rankins Springs, and in the north-east of Tasmania. It grows in mallee communities or coastal cliffs on sandy soil over limestone, the top layer of soil often neutral to acidic, while the subsoil is highly alkaline.
