Robust Spider Orchid (Arachnorchis valida - formerly Caladenia valida)

Flowers in Spring (Sept - Nov) - favours heathy eucalypt forest. Found mainly in Portland area but also from Anglesea.

Rather uncommon.  Difficult to find because of its growing habitat.  The photo ruler indicates the height of this particular plant - a total of 8.5 inches (22cm).  Labellum has extensive maroon apex and saw-tooth calli.

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).


Pink-lip Leek Orchid (Prasophyllum sp aff fitzgeraldii)

Flowers in Spring (Oct - Nov), favours forest with heath & grassy under-story.  It is one of the threatened orchid species in Victoria.

This orchid, thought to be endemic to South Australia, has been found in the Stawell district.  The flower is very fragrant; the callus plate can be cream to dark pink.  The photo ruler indicates the height of this particular plant - a total of 9 inches (23cm).  The leaf is onion-like and fibrous.

Bees and wasps are reported to be main pollinators of this genus although syrphiid flies are also frequent visitors.
