Abstract
The new species Hibbertia advena T.Hammer & Toelken is described. It occurs in north-east Queensland but shares a strong morphological affinity with members of the H. exasperata (Steud.) Briq. species group, which are widespread in south-west Western Australia. This may be an example of a very wide transcontinental disjunction in Australian Hibbertia. The biogeographic significance of such disjunctions is briefly discussed, pending further insights when a more complete molecular phylogeny of the genus is generated.
