You are looking at the flower head of one of several Melaleuca species that are commonly known as “honey myrtles”.
The Melaleuca genus has more than 300 members, most of them endemic to Australia; it also includes all of the bottlebrushes and paperbarks, plus some of the so-called tea-trees.
The genus is part of the Myrtle family.
I am pretty sure that the picture shows Melaleuca nesophila, a WA-endemic which naturally occurs only in the Albany-Esperance region.
It is however, a popular garden plant, commonly found in Australian gardens and parks.
I took the photo at 4.23 pm on 29 September 2025 in Hollywood Reserve, adjacent to Perth’s Karrakatta Cemetery.
This post’s sequel will show an “inhabited” flower head of the same species.
