Lomatia

Lomatia is a genus of 12 species of evergreen flowering plants in the protea family Proteaceae. Within the family, they have been placed, alone, in their own subtribe, Lomatiinae according to Johnson & Briggs 1975 classification of the family and subsequently in Flora of Australia (1995).

This article is about the plant species. For the genus of insects, see Bombyliidae and Lomatia belzebul.

The genus has a Pacific Rim distribution, with members native to eastern Australia and southern South America, forming a part of the Antarctic flora. The species range from prostrate shrubs less than 0.5 m (1 ft 8 in) tall to small trees up to 12 m (39 ft) 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 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.[1] Strong genomic filters may facilitate continued gene flow between species without the danger of assimilation.
