Calothamnus species in Fitzgerald River and surrounds

Updated 28/2/2024. Index to my other posts.

The purpose of this post is to gather some information about the Calothamnus species in Fitzgerald River and surrounds to facilitate their identification.

Twelve species of Calothamnus are shown by Florabase to be in the area (shires of Jerramungup, Kent, Lake Grace and Ravensthorpe). I have shown the Local Government Areas in which the species occur as the area is so large:
