Cassinia flowers late Spring to Summer, on 2-3 m high bushes on the lower slopes of Barrm Birrm. You will see it as you drive along Gap Road.

It is an erect shrub 1–2.6 m high; trunk and older branches with smooth to lightly stringy light- to dark grey bark, longitudinally fissured on the trunk, becoming black and flaky, with the young twigs green to reddish. What you will see most often in Barrm Birrm is Shiny Cassinia, and the giveaway sign is the longer leaves of this shrub.

There are two other versions of Cassinia in Barrm Birrm, with different sized leaves, and once you get your eye in, you'll find it right through Victoria, in different variations. I've heard it called Chinaman's Tea, along with the story that it was sometimes a fallback when no other tea was around.

With its fresh white flowerheads, it is a treat to the eyes, but this version above has a lovely pink hue. The genus Cassinia was first formally described in 1817 by the Scottish botanist Robert Brown, who named it after the French botanist Alexandre de Cassini. It is part of the family Asteraceae, native to Australia and New Zealand.
