Reinstatement and revision of the genus Marianthus (Pittosporaceae)

Abstract

Cladistic analyses of the family Pittosporaceae in Australia have indicated that the genus Marianthus needs reinstatement from Billardiera. Here, Marianthus is re-circumscribed and monographed. Fourteen species are recognised, excluding the now reinstated Rhytidosporum. In this treatment, two species are reinstated (M. microphyllus, M. tenuis), a new combination is made (M. mollis) and three species are described for the first time (M. dryandra, M. paralius and M. sylvaticus).
