Orchids of the Dandenongs

6 November 2011

Started off in Baluk Willam and lucky to still see numerous sun-orchids in flower, including this one that I have called Thelymitra pauciflora, but I can't tell the difference between that and T. arenaria, T. pallidiflora or T. brevifolia (excluding minor color variations).

In the afternoon I went to Sherbrooke Forest for a study of the various bird-orchids. Here, within metres of each other, are many plants of Chiloglottis/Simpliglottis valida, Simpliglottis cornuta and fewer Simpliglottis jeanesii. Additionally there are variations that appear to be hybrids between at least one of the above pair but its all too confusing for me to be certain about.
