Abstract

The genus Homoranthus A.Cunn. ex Schauer currently includes 31 endemic species in eastern and southern Australia. In a c. 400,000-hectare section of the New England Tableland bioregion, there are seven rare described species of Homoranthus endemic to granite outcrops, six of which are each found only in a single small, isolated distribution. The exception, Homoranthus lunatus Craven & S.R. Jones has populations 70 km apart and broadly spans the range of the other species. Genetic analysis of the seven Homoranthus species in the region revealed a phylogenetically distinct lineage indicative of an eighth, undescribed taxon. Morphological assessment of H. lunatus has led to the formal recognition and conservation assessment of H. wissmannii Pemberton & McMaster (Myrtaceae), with a revised assessment for H. lunatus.
