Today I simply publish a few more Orchid photos from yesterday's outing in the Shoalhaven area.
Dark Mosquito Orchid. Hard to spot, in amongst the leaf litter, in shaded positions, usually.
Large Mosquito Orchid.
The hooded dorsal sepal is distinctive. In general, these plants I saw were greyer and paler than the other species. They are perhaps a little larger, though, in the world of Mosquito Orchids, that is a relative term.
I would have to say, it takes a close examination to make sure of which species you are looking at.
Long-leafed Greenhood, (formerly Pterostylis longifolia). It is good to get an image of the flower fully open, as in this shot. It has leaves along the flower stem (cauline leaves). A number of Greenhoods have this characteristic, but this species has relatively long leaves (hence its name).
You can see the top leaf in this image.
Fringed Helmet Orchid.
This is another photo to go with the one from yesterday where the two flowers were sprinkled with sand. (Formerly classified in the Corybas genus.)
Toothed Helmet Orchid (not the "plum-coloured" Helmet Orchid as I had wondered).
These flowers were standing up nicely on little white stems, and there is an obvious pair of appendages underneath the "labellum". The pale grey-green "helmets" are distinctive.
The brown-tinged, and heavily rounded tip of the "hood" is obvious in this photo. The two "points" are strongly distorted to spread low and wide, unlike most Greenhoods, where they form prominent "ears".
(with bronze fly)
I mentioned these flies yesterday. Here is another one, which I had not even noticed when peering through the view-finder yesterday. I only found it when processing the photos.
Speculantha sp. aff parvifolia
This is one of the brownish "tiny greenhoods", which have not as yet been properly distinguished. The taxonomist are busy working through the Orchid family, but have not yet thoroughly revised this group yet. For the moment, this one I will label with the phrase "sp. aff' which is shorthand for "species close to ...".
I have seen true Tiny Greenhoods, with green flowers. Then I have also seen tiny brown Greenhoods, growing on Tourist Road, with stems a mere 4 inches high, no more, and dark brown tip of the "hood". Also, those specimens had points which did not exceed the hood.
By contrast, this flower had a stem at least 12 inches high, had quite prominent stem leaves, (with rosette leaves forming at the base as well), and ears which exceed the hood, and curl back in a charming "windswept" look. (Click on the image for a better look, and then click on the link above, to see the other similar flowers, to contrast the two groups of related plants).
