Verticordia endlicheriana Yellow Feather Flower Endemic
The unofficial common name "Yellow Feather Flower" isn't very helpful as there are quite a few Verticordia species with yellow flowers. The thick leaves and groups of corymbose flowers on a quite small shrub suggest that this is a correct identification but let me know if you are a Verticordia expert and think differently. It can be reddish in colour as well as yellow and there are several varieties.
It is found from just south of Geraldton through the Wheat Belt to the south coastal plain approximately to Denmark, and can be found as far east as Fitzgerald River National Park.
