Unusual new species of Styphelia (Ericaceae, Epacridoideae, Styphelieae) from north-eastern Australia.

Styphelia geniculata Crayn and S. piliflora Crayn are described, phylogenetically placed and compared with related species. Their relationships within Ericaceae tribe Styphelieae, resolved by phylogenetic analysis of plastid and nuclear DNA sequences, support their description in the expanded genus Styphelia. Illustrations, pollen scanning electron micrographs, distribution maps and a key to the species and related northern Queensland taxa are provided, along with notes on the ecology and conservation status
