Sean Spence Posted November 8, 2013 Report Share Posted November 8, 2013 Below are a number of images of Australian terrestrial orchids that I have encountered during many field trips mainly around the state of Victoria over the past few years. I'll start with my favourite group, Oligochaetochilus (or rufa group Pterostylis if you prefer). On this group you'll notice the small triggered labellum that imitates a small insect. These look very much like little beetles. This group favours incredibly dry habitats, often desert-like and flowering occurs at the end of spring, after the rosette of leaves have dried and shrivelled. They are very difficult to find as the flowers are well camouflaged. O. pusillis a tiny species. O. aciculiformis O. squamatus O. hamatus O. despectans- very rare and very low to the ground. O. linguus- in southern NSW last weekend O. boormanii- incredibly difficult to get the whole flower of this species in focus. O. maximus- photographed yesterday. O. setiferus O. woollsii- the best of the best and one of the rarest in Victoria. Only around 100 plants in the state and we were lucky enough to find one of them. and yes, I do grow one species, O. petrosus from southern NSW. Next up, the remainder of the greenhood group. Thanks for looking. 2 Quote Link to comment Share on other sites More sharing options...

tropicbreeze Posted November 17, 2013 Report Share Posted November 17, 2013 Although they're rather diminutive, they more than make up for it with their bizarre forms. Often wish I could grow some, but just have to be content with seeing them in habitat, or digitally. Quote Link to comment Share on other sites More sharing options...
