What is "toronia"

Toronia is a genus of tree in the family Proteaceae that contains a single species, Toronia toru, which is found in New Zealand. The genus is closely related to the large genus Persoonia, and in fact this species was long regarded as one until placed in its own new genus by Lawrie Johnson and Barbara G. Briggs in their 1975 monograph "On the Proteaceae: the evolution and classification of a southern family".

However, unpublished data indicates Toronia, Garnieria and Acidonia all lie within the large genus Persoonia.
