Abstract
Phylogenetic analysis of nrDNA ITS and tmL (UAA) 5' exon-tmF (GAA)
chloroplast DNA sequences from 17 species of Pelargonium sect. Peristera, together with
nine putative outgroups, suggests paraphyly for the section and a close relationship
between the highly disjurmt South African and Australian species of sect. Peristera.
Representatives from Pelargonium sectt. Reniformia, Ligularia s. 1. and Isopetalum (the St.
Helena endemic P. cotyledonis) appear to be nested within the Peristera clade. The dose
relationship between the South African and Australian Peristera is interpreted as being
caused by long-range dispersal to Australia, probably as recent as the late Pliocene
