Green-comb Spider Orchid Arachnorchis dilatata

syn. Caladenia dialata
Like all the Spider Orchids, this one has a central flower with elongated petals waving out giving a look to that of a spider (hence their name). These ones were all found along the road near the Baluk Willam Flora Reserve. Although there is a sign warning that disturbance may damage protected flora, its always a concern when such a plant is found essentially unprotected. There were a few scattered along a few metres, in one spot I was able to capture three in the same photo.

A similar orchid is Arachnorchis phaeoclavia and C. tentaculata, and indeed I'm not 100% about this identification.
