Mallee Spider Orchid (Arachnorchis verrucosa - formerly Caladenia verrucosa)

Flowers in Spring (Sep - Oct) - favours open woodland among mallee vegetation on the swales or flats in well-drained soil.

The flower is small with thick yellow clubs on the sepals.  The photo ruler indicates the height of this particular plant - a total of 8 inches (20cm).

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).

Erect Midge Orchid (Corunastylis arrecta formerly Genoplesium arrecta)

Flowers in Summer (Dec - Jan), favours sub-alpine shrubby understorey in well drained soil.

Labellum has hairy margins but petals are hairless.  Lateral sepals are erect.  The photo ruler indicates the height of this particular plant - a total of 9 inches (23cm).

These are poorly studied when it comes to pollination but some of the genus are known to attract small flies.
