Andersonia R.Br. is a genus of small to medium-sized shrubs endemic to the south west of Australia. It currently comprises 22 recognized species and is one of three closely related genera which form the tribe Cosmelieae.Andersoniais distinct from the closely relatedSprengeliaSm., but serious problems in the subgeneric taxonomy have been identified. A strict application of the current descriptions of two subgeneric divisions does not include two species, and a full assessment of the homologies of the leaf-organs on which these sections are based has never been made. At species level a large number of new taxa have been identified, and some previous combinations are questionable. This paper outlines these problems and ways in which they are being addressed. Some urgency is attached to the taxonomic work because of the threat posed to the genus by dieback caused by the fungusPhytophthora cinnamomi.
