Grevillea divaricata R.Br., 1830:20

 

 

Taxonomy & Nomenclature

 

 

Conservation Status

Extinct (Humphreys et al., 2019)

Last record: 1823

IUCN RedList status: Critically Endangered (Possibly Extinct)

 

Listed as extant in the wild by (Abeli et al., 2022 [preprint]), but this may be a result of confusion with the closely related G. rosmariniflolia which was rediscovered after many decades, especially since further up the preprint they state that they could not get any updates on the taxon.

 

Distribution

north of Bathurst, New South Wales, Australia
