N2 - A new genus, Androcalva C.F.Wilkins & Whitlock, is here described and includes 22 species previously described as Commersonia, four species formerly described as Rulingia and seven new species, including A. aphrix C.F.Wilkins, A. perlaria C.F.Wilkins, A. bivillosa C.F.Wilkins, A. adenothalia C.F.Wilkins, A. fragifolia C.F.Wilkins, A. incilis C.F.Wilkins and A. lachna C.F.Wilkins. Rulingia pauciflora Turcz. is here placed in synonymy with C. gaudichaudii J.Gay as A. gaudichaudii. Recognition of Androcalva is supported by the results of a previous molecular phylogenetic analysis demonstrating that neither Rulingia nor Commersonia as previously circumscribed is monophyletic. Species of Androcalva share characters of extrorse anther dehiscence and glabrous central staminodes. In contrast, species in the redefined Commersonia have anthers with sublatrorse dehiscence and hairy central staminodes. Taxonomic descriptions, a key, distribution maps, conservation status and illustrations are presented.
