Thanks Ciaran. I have to say after the last couple of weeks of my Cassinia sightings that I'm now totally confused. What are the key things you look for to distinguish between the two?

Leaves to 40 mm long, if ever to 50 mm, then adaxial surfaces aculeate to shortly hispid; margins strongly recurved to revolute; foliage not viscid (Cassinia aculeata)
At least the longest leaves mostly 40 mm long or more, adaxial surface smooth; margins not or barely recurved; new growth typically rather viscid (Cassinia longifolia).
So effectively from photos we are making a judgment about relative leaf length and/or using the leaf margins. C.longifolia should be sticky in the field (hence the common name) which is a super helpful tip when you've got the plant in hand!

Thanks for the tips, I'll see if I can lift my game. I'm aware of the sticky feature but this specimen was not obviously sticky; I'm wondering if water stress reduces the stickiness (despite the recent rain, this specimen because of its location on a rocky slope was still looking pretty stressed).
