Isopogon anethifolius, Maranoa Gardens

Isopogon is a genus of about forty species of mainly low-growing and prostrate perennial shrubs in the family Proteaceae that are endemic to Australia. They are found throughout Australia, though Western Australia has the greatest variety with 27 of the 35 species found there. They are popularly known as drumsticks due to the shape of their inflorescences.

Several species are grown in gardens, though they are nowhere near as well known or cultivated as their fellow Proteaceae members Grevillea or Banksia.

Taxonomy

The genus Isopogon was first formally described in 1809 by Joseph Knight On the cultivation of the plants belonging to the natural order of Proteeae, preempting publication of the same name by Robert Brown in his book On the natural order of plants called Proteaceae.

Genetics

Isopogon have 13 haploid chromosomes.
