All have a labellum on which can be found small projections called calli.

From Greek – calos (beautiful) and aden (glands).

Caladenia can be divided into four groups according to distinct visual differences.

Sepals and petals Labellum Leaf
1. Spider Orchids long fringed or toothed narrow
4. Fairy Orchids short and spreading fringed broad
2. Crested Orchids shorter smooth edges and prominent calli narrow
3. Dragon Orchids shorter hairy with horn-like appendages broad

These orchids have an affinity with both the spider and crested orchids.
The Lazy Spider Orchid has a smooth edged labellum with prominent calli yet upright sepals and petals.
The Dancing Orchid looks like a crested orchid but has a fringed labellum like the spider orchids.

    You have a collection of very beautiful photos. I too am compiling a collection of photos of our local wildflowers. I became particularly interested in the orchids because of there amazing shapes and in many cases the difficulty in finding them. Last season I was very lucky to stumble across a colony of 5 Flying Duck orchids which I had never found before.

    Beautiful photos. I love to stroll through Wireless Hill Reserve about this time of the year. I will be taking a trip down through Lake Grace and Esperance early October and hope to see some orchids. I love all wildflowers, but yes, orchids are special.
