Periomphale Baill. (incl. Pachydiscus Gilg & Schltr. and Memecylanthus Gilg & Schltr.) from New Caledonia is reduced to Wittsteinia F.v.M. from New South Wales. This genus occurs also in New Guinea. Three transfers are made. A new monotypic genus of the group Crispiloba is described from Queensland, based on Randia disperma S. Moore. A general discussion is held on the features of the group and the affinities within it. It has become clear that it has no alliance to the Caprifoliaceae but must be regarded as allied to Saxifragaceae sensu lato, either as a distinct family or as a subfamily. A key is given to the three genera: Alseuosmia from “New Zealand, Wittsteinia from New South Wales, New Caledonia and New Guinea, and Crispiloba from Queensland.
