Rourke (1976) dismissed Salisbury's name humifusa as the type could not be traced and "the description is so vague that it cannot be applied with certainty". However, taken in conjunction with the section Salisbury placed it in (petals beyond the anthers hairless), the description is unambiguous. It remains to find the herbarium specimen collected by Roxburgh to locate the type.
