Taxonomy
Within the family, they have been placed, alone, in their own subtribe, Lomatiinae according to Johnson & Briggs 1975 classification of the family
This was subsequently followed in Flora of Australia (1995)
Species relationships
Genetic analysis using microsatellite markers showed that species found close together geographically are most closely related to each other
Lomatia dentata, then L. hirsuta and L. ferruginea all diverged successively from the lineage that gave rise to Australian species
The three Tasmanian species (with L. tasmanica sister to the other two species) are sister to the mainland Australian group
L. tasmanica of the three tasmania species, happens to be one of the most endangered species
On mainland Australia, the far northern L. fraxinifolia is sister to the other five species, all of which are found in southeastern Australia
L. fraseri and L. myricoides are sister taxa, with L. ilicifolia sister to them, while L. arborescens and L. silaifolia are each other's closest relatives
Strong genomic filters may facilitate continued gene flow between species without the danger of assimilation
