Rosella Spider Orchid (Arachnorchis rosella - formerly Caladenia rosella)

Flowers in Spring (Aug - Sep) - favours box-stringybark woodland with open understory.

Endangered orchid - often the first to flower in Spring.  The photo ruler indicates the height of this particular plant - a total of 5 inches (13cm). 

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).


Spiral Sun Orchid (Thelymitra matthewsii)

Flowers in Spring (Sep), favours poor gravelly soil, mainly coastal, often in areas that have been disturbed.

This small orchid is listed as vulnerable because of the limited populations.  The flower is temperamental and reluctant to open unless circumstances are exactly right.  The photo ruler indicates the height of this particular plant - a total of 5.5 inches (13.5cm).

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