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.

This study of the vegetative anatomy of Picrodendron and some of its putative relatives has been undertaken in order better to understand its natural relationships. Despite the number of anatomical studies in the literature (Jadin, 1901; Solereder, 1908; Boas, 1913; Webber, 1936; Heimsch, 1942; Record & Hess, 1943; Metcalfe & Chalk, 1950), our information on the anatomy of Picrodendron is still incomplete· for example, nodal and petiolar anatomy has apparently never been described. Furthermore, with the exception of Record and Hess (1943), who discussed Picrodendron in a family by itself, other anatomists have compared Picrodendron only with members of Simaroubaceae, …
