Plain-lip Spider Orchid (Arachnorchis clavigera - formerly Caladenia clavigera)

Flowers in Spring (Sept - Nov), favours open forest and woodland with well-drained soil.

Widespread and common, growing in loose colonies.  The labellum is neither fringed nor toothed.  The photo ruler indicates the height of this particular plant - a total of 6.5 inches (17cm).

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).


Tiny Fingers (Petalochilus pusillus - formerly Caladenia pusilla)

Flowers in Spring (Sep - Nov), favours heathland or open forest growing in sandy soils.

This diminutive Petalochilus has colourful flowers, incurved dorsal sepal and lateral sepals often united at base.  The photo ruler indicates the height of this particular plant - a total of 4.75 inches (12cm).

Pollination of the Petalochilus species has been studied very little but it is thought that smaller ones are pollinated by bees.
