Amazed to find these snail orchids (Pterostylis sp.) growing in the small amount of rubble on a granite boulder over 2 metres above the surrounding ground. The 1st photo below is of the boulder. The 2nd photo is zoomed in with Circle indicating position of orchids contained in video 1 and the Arrow indicates location of the 4 orchids in video 2. The 4 orchids are also the Feature Image of this post.
