Large Striped Greenhood Orchid (Diplodium robustum - formerly Pterostylis robusta)

Flowers in Autumn/Winter (May-Sept), favours poor soils growing in sheltered situations in drier forests and sporadic.

Labellum generally not visible.  The photo ruler indicates the height of this particular plant - a total of 3 inches (8cm) with the flower being 2.5cm X 1cm.  Sepal tips curve forward.

Pollinator uncertain but all known pollinators of the Genus Diplodium have been male insects of the fungus gnat and mosquito family.


Heart-lip Spider Orchid (Arachnorchis cardiochila - formerly Caladenia cardiochila)

Flowers in Spring (Aug - Sept), favours heathy forest, woodland and mallee - usually in sandy soils.

Dainty, small flowered spider orchid which is particularly common in South Australia.  The photo ruler indicates the height of this particular plant - a total of 3 inches (8cm).

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).
