Unique Orchids

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.
