Crimson Spider Orchid (Arachnorchis clavescens - previously Caladenia concolor)

Flowers in Spring (Sep - Oct) - Heavy soils, often rocky, on ridges or slopes in woodland and box-ironbark forest.

This orchid is considered endangered because of the limited sites and few plant numbers.  Although the flowers are usually dark red, it does have some variance in colour forms.  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).


Golden Cowslips (Diuris behrii)

Flowers in Spring (Sep - Nov), favours moist grassy areas in open forest and woodland.

Distinguished by its robust habit as well as larger flowers.  The photo ruler indicates the height of this particular plant - a total of 10 inches (25.5cm).  Some flowers can have dark streaks.

The colourful flowers of the Diuris genus appear to be pollinated mainly by small bees but syrphiid flies and beetles may also be pollinators.
