Are Billardiera and Calothamnus both types of genuses?
Billardiera Billardiera is a genus of small vines and shrubs which is endemic to Australia. The genus was first formally described in 1793 by botanist James Edward Smith who named it in honour of Jacques Labillardière, a French botanist.
Calothamnus validus Calothamnus validus, commonly known as Barrens clawflower, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is an upright or rounded shrub with stiff, cylindrical but not sharply pointed leaves and red, 4-part flowers. The common name derives from the location, West Mount Barren, where it was found by Spencer Moore, the author of its formal description. It is commonly cultivated and has sometimes escaped from gardens in Western Australia.
