Crucifix Spider Orchid (Arachnorchis cruciformis - previously Caladenia cruciformis)

Flowers in Spring (Aug - Oct) - Prefers grey sandy-loam soil in heathy woodlands.

Probably endangered because it is found in limited sites with few plants.   Common name comes from the rigid spreading tendency of the lateral sepals and petals. The photo ruler indicates the height of this particular plant - a total of 9 inches (23cm). 

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).


Tawny Spider Orchid (Arachnorchis fulva - previously Caladenia fulva)

Flowers in Spring (Sep - Oct) - Prefers drier forest with well drained soil and sparse under-story.

This orchid is endangered because it is confined to a very limited growing area.   There is a large variance in the labellum colours. The photo ruler indicates the height of this particular plant - a total of 7.5 inches (18cm). 

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).
