Eastern Bronze Stegostyla (Stegostyla transitoria - formerly Caladenia transitoria)

Flowers in Spring (Oct - Nov), favours heathy woodland or in heath often in poor stony soils.

Poorly studied because of short flowering season and flower may not open at all if weather is cold and wet.  The bronze tips on the petals is an identifying feature.

Pollination of the Stegostyla species has been studied very little but it is thought that smaller ones are pollinated by bees.


Large White Spider Orchid (Arachnorchis venusta - formerly Caladenia venusta)

Flowers in Spring (Oct - Nov), favours heathy woodland in sandy soils, especially on the margins of swampy areas. 

Known to flower more abundantly after fires.  This tailed spider orchid has a labellum that is lined with fine reddish-purple teeth.  The photo ruler indicates the height of this particular plant - a total of 16 inches (41cm), including the sepal.

Pollination of the Arachnorchis species has been studied very little but it is thought that spider orchids are generally pollinated by pseudocopulation (male thynnid wasp).
