ex Knight Lomatia is a genus of 12 species of evergreen flowering plants in the protea family Proteaceae.
The genus has a Pacific Rim distribution, with members native to eastern Australia and southern South America, forming a part of the Antarctic flora.
Lomatia dentata, then L. hirsuta and L. ferruginea all diverged successively from the lineage that gave rise to Australian species.
L. tasmanica is one of the most endangered species, due to its inability to reproduce sexually.
