Petalacte has been in continuous use for this genus of 1-3 species since proposed by D. Don. The only exception was Lessing's misuse of Petalolepis Cassini, from which he excluded the two original Australian species and substituted two from S. Africa. Lessing was not followed by later authors.T he genus was recently revised by Lundgren (in Bot. Notiser 127: 119-124. 1974) and this revision may be consulted for full references.
