|Summer Greenhood, Diplodium decurvum, Tidbinbilla Nature Reserve near Canberra.|
The hood, or galea, covers the top of the flower; it is hard to make out the three different parts of it.
|Snail Orchid Linguella sp., Alligator Gorge, South Australia.|
There are over 30 species of the little snail orchids, mostly in Western Australia;
unfortunately, at last count only five of them had been described!
|Large Mountain Greenhood Pterostylis monticola, Namadgi National Park near Canberra.|
Some 25 Australian species remain in Pterostylis under Jones' taxonomy. Here the labellum protrudes.
|Nodding Greenhood Pterostylis nutans, Micalong Falls, New South Wales.|
Not dozing, they always look like this!
|Trim Greenhood Taurantha concinna, Callala, south coast New South Wales.|
Again the labellum is obvious, protruding through the join of the two lateral sepals;
this angle is the sinus, and is used for identification.
|Black-tip Greenhood Hymenochilus bicolor, Munghorn Gap NR, central western New South Wales.|
These flowers are tiny. In the middle flower the fly-like labellum is exposed; in the other two it has
snapped shut, locking the insect inside.
|Sikh's Whiskers (!) Oligochaetochilus boormanii Weddin Mtns NP, south-western slopes New South Wales.|
Not all greenhoods are just green!
|Jug Orchid Stamnorchis recurva, Twin Creek NR, Western Australia.|
The only one of its genus, restricted to the west, and quite unmistakeable.
|Unnamed Plumed Greenhood Plumatichilus sp. Alligator Gorge, South Australia.|
Only four of the 14 known species of plumed greenhoods have been described;
they have in common these wonderful long yellow hairs along the labellum.
