There are about 1,000 species of Orchids in Australia and as many as 35,000 species worldwide - making it the largest flower family.
There is only one commercial substance produced from Orchids - vanilla - which is produced from the fruit pod of Vanilla planifolia. For a full description of this marvelous orchid visit www.orchidsaustralia.com/vanilla.html
Although Orchids vary greatly in form, colour and size, their flowers are composed of 6 segments. The outer 3 segments are the sepals; and inner three segments are the petals. The third petal becoming a lip or labellum.
Although the sepals and two of the petals vary greatly across the orchid family, it is the third petal (the labellum) and the column that achieve fascinating, and at times bizarre shapes, sizes and colours.
Insects being the principal pollinators of orchids, often use the labellum as a landing place.
A seedpod may contain more than 2 million seeds.
The Small Waxlip Orchid (Glossodia minor) kindly consented to be used as a model for this botany lesson. The photos above were taken in the Lane Cove National Park.
This web page contains orchids from the greater Sydney area. Please take a look at the Western Australian Orchids web page.
The Spotted Sun Orchid (Thelymitra ixioides var. ixioides), also known as the Blue Sun Orchid has dark blue dots on its upper three segments.
The flower is 25mm wide, but needs a sunny day to open.
It is best identified by the finger like papillae as not all Spotted Sun Orchids have spots as this image shows.
They also have a hint of vanilla when smelt.
The photos of the Spotted Sun Orchid were taken in Lane Cove National Park.

 Donkey Orchids are easily recognised by their donkey ear-like petals with two leg-like sepals below. (Lane Cove National Park) |

 Also known as the Duck Orchid due to is bill or tongue like labellum - which is around 30mm in length. The sepals and other petals are small and spike like. (upper Blue Mountains) |
 This orchid is all labellum. The other petals and the sepals looking more like leaves. It is also known as the Bonnet Orchid and the Tartan Tongue Orchid. (Lane Cove National Park) |
 Spring flowering, the Copper Beard Orchid is identified by the two blue plates on its labellum. (Lane Cove National Park) |
 Spring flowering, its thick beard at the top of the labellum differentiates it from the other Beard Orchids. (Lane Cove National Park) |
