Most of the orchids on this web page are from the Stirling Range National Park and were photographed during a Floral Secrets Orchid Tour taken on a Saturday morning in October. The Park is 400 south-east of Perth.
Within the 116,000ha of the Park, there are 1,500 plant species - including 123 species of orchids.
The Tour is provided by Stirling Range Retreat, and in our case was conducted by Ayleen Sands, whose knowledge, passion and charm made it an experience to be remembered and treasured.
Notes taken on the Tour, as well as its handouts allowed the identification of the orchids and much of the detail provided below.
Reference has also been made to the superb Western Australian Herbarium FloraBase and the Orchids of South-West Australia website.
Unless indicated, the photos were taken in the Stirling Range National Park.
The orchid at the top is the stunning Purple Enamel Orchid (Elythranthera brunonis). It is widespread and the flower is 30mm in diameter.
The Butterfly Orchid (Caladenia lobata) above shows the remarkable, if not bizarre shapes of orchids. Its crimson lip quivers in the breeze. It is a Spider Orchid and its "wingspan" would be 70mm.
[A new classification is proposed for the Caladenia genus that would see the Spider Orchids have their own genera - Arachnorchis.]
Sun Orchids are at times difficult to identify from each other - especially when hybrids are involved.
The Shy Sun Orchid (Thelymitra graminea) to the left was found on Wave Rock.
The Scented Sun Orchid (Thelymitra macrophylla) to the right was found in Albany.
The Blue Lady Orchid (Thelymitra crinita) to the right was found in Perth.
It can be distinguished from the Scented Sun Orchid by the purple tufts on its column - see the close-up to the right shows.

This Donkey Orchid was found on Wave Rock. |
Another member of the Donkey Orchid herd - its name is very fitting. |

The distinctive striped labellum readily identifies this orchid. |
This splendid "standard-looking" orchid was found north of Margaret River. |
Another magic spider orchid - looking a bit like some discarded maroon ribbon. The full image shows a seed pod. |

Apparently, the labellum of the Dragon Orchid resembles a female Thynnid Wasp. In addition it excretes the scent of this wasp. |
The male Thynnid Wasp becomes stuck on the labellum and the only way clear is towards the column - thus becoming a pollinator. |
Further details of this intriguing process can be found in this article on Orchid Pollination. There are over 12,000 species of wasp in Australia. |

This beautiful orchid was found in woodland near Pemberton. It was growing out of the stump of a fallen tree. |
Easily identified by its elongated petals looking like rabbit ears. |
One of the more common orchids - often appearing in groups. This one was found near Pemberton. |

This stunning orchid has the longest petals and sepals - wisping and waving. |
One of the more pronounced displays of the labellum and column with the remaining petals and sepals attracting attention. Also known as the Green Spider Orchid. |
Yet another most remarkable spider orchid. |

A spider orchid with so much character. Its labellum looks like a handlebar moustache |
Although not a great photo, as it was past its best, it has been included as it is a threatened species - having been declared "rare". |
One of the more flashy and bold spider orchids. |
