s less than tall to small trees up to tall. 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'' is one of the most endangered species, due to its inability to reproduce sexually. 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.
