Hairy Spider Orchid (Arachnorchis villosissima - formerly Caladenia villosissima)

Flowers in Spring (Sept - Nov), favours grassy woodland with Eucalyptus leucoxylon & camaldulensis.

Medium-sized flowers with calli extending into the reddish area of the labellum.  The photo ruler indicates the height of this particular plant - a total of 6 inches (15cm).  It is identified by the large densely hairy leaf.

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


Basalt sun Orchid (Thelymitra gregaria)

Flowers in Spring (Oct - Nov), confined to Western Victoria growing in native grasslands.

This orchid has a clumping habit and is very endangered because of loss of habitat.  The photo ruler indicates the height of this particular plant - a total of 7.5 inches (9cm).

Believed to be pollinated by bees but if not, then the flowers will self pollinate.  Almost all species have flowers that open only on sunny days - hence the name of 'sun' orchid.
