Trunk is a bit thin for normal C. australis. Need a c loser look at the trunk.

No C.cooperi there as far as I know.

I have seen similar plants near Crystal Creek near Murwillumbah that keyed out as C. australis, but were morphologically far more gracile than the typical thick-trunked C. australis we see in the Canberra and South coast region (ie gracile like this specimen). Needs further investigation. Interesting.

It is very unikely that C. cooperi ocours in natural rainforest that far south. Its S limit naturally is about Lake Conola.

Perhaps another Cyathea species, then? It definitely does not look like the C. australis that I'm familiar with.

The only other species is Cyathea leichhardtiana, and it is not that. This is not on my list for that site, but C. australis is.

OK. C. australis it is. It strikes me that there are variations in C. australis that might require some differentiation.

I revisited the site this week and the only two tree ferns in that valley are C. australis and D.antarctica.
