Hi Elfi I am sorry I do have have the best eyesight but if it looks something like my one on the link below I do realise the outer petal are coloured different so search the other name that is on that link..

I put a lot of my ID on the US website as there is not much traffic here these days.

Here is a link that might be useful: Garden Web Orchid Forum

Thanks MM! It does look similar but your flower seems to be quite a bit larger, mine are only small and they are the ones growing everywhere here in the bush high up in the forks of the trees. That's why I thought it could be a wild one and was wondering if the Aussies gave it a name.

Elfi I took those pics with my macro lens then cropped it so members could see it better for ID.

I would do a search of Dendrobium and Sarcochilus orchids as they are natives and smaller..

Cheers...Misty.
