Calothamnus rupestris ?;
Flora Australia-85: Callystemon villosus,-Myrtaceae.
Callistemon species have now been transferred to the genus Melaleuca by Australian botanists and most information is now related to Melaleuca. This might help if you are looking at the excellent online resources for the Australian Flora.
There is no sp. such as Callistemon villosus ( Y=I ?) and did not appear in IPNI, POWO, GBIF and CoL.
However, the sp. looks matching to Melaleuca hislopii Craven & R.D.Edwards syn: Calothamnus villosus R.Br.
Many species from Australia look similar by checking on net.
I think calyx holds the keys, which is not clear here.
