Etymology:   

• Lomatia:  from Greek loma, a fringe, referring to the wing that surrounds the seed

• Evergreen flowering plants

• The species range from prostrate shrubs less than 0.5 m  tall to small trees up to 12 m tall

Habitat:   

Distribution:                  

• The genus has a Pacific Rim distribution, with members native to eastern Australia and southern South America, forming a part of the Antarctic flora

Species:                     

• World:            15 

• Australia:        9 

Additional notes:     

• 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

• Species in Australia:

  • Lomatia arborescens - eastern Australia

  • Lomatia fraseri - eastern Australia

  • Lomatia milnerae - Queensland

  • Lomatia ilicifolia - eastern Australia

  • Lomatia myricoides - southeastern Australia

  • Lomatia polymorpha (mountain guitarplant) - Tasmania

  • Lomatia silaifolia - eastern Australia

  • Lomatia tasmanica (King's lomatia) - Tasmania

  • Lomatia tinctoria (guitarplant) - Tasmania

• Species elsewhere:

  • Lomatia dentata - Chile, Argentina

  • Lomatia ferruginea - Chile, Argentina

  • Lomatia hirsuta - Chile, Peru, Argentina

  • Lomatia occidentalis - (Eocene fossil records) Patagonia 

  • Lomatia patagonica - (Late Oligocene-Early Miocene (Ñirihuau Formation) fossil records) Patagonia

  • Lomatia preferruginea - (Middle Eocene fossil records (Ventana Formation) Patagonia
