Charming Spider Orchid (Arachnorchis amoena formerly Caladenia amoena)

Flowers in Spring (Aug - Sep), favours slopes in open forest with well-drained soil.  All plants were found growing in moss.

This is a very small greencomb spider orchid; labellum margins have very few teeth.  Considered endangered and found in only a single location.  The photo ruler indicates the height of this particular plant - a total of 1.5 inches (4cm).

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).


Maroon Leek Orchid (Prasophyllum sp aff fitzgeraldii E)

Flowers in Spring (Sep - Oct), favours yellow gum  with heath understorey and sandy soils.  It is considered to be endangered due to loss of habitat.

This orchid, thought to be endemic to South Australia, has been found in the Tallagiera district.  It has a common name of 'Bright Shiny Maroon'' in Bob Bates' CD.  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.
