Flat Marsh Orchid (Hydrorchis orbicularis)

Flowers in Spring/Summer (Sep - Dec), favours swampy and other wet areas to allow base of plant to be immersed in water.

Labellum is orbicular, fleshy and lacks calli.  The photo ruler indicates the height of this particular plant - a total of 11 inches (28cm).  The flower is minute and can be either green or red.

This orchid is self pollinating and is reproduced through seed as well as the production of extra tubers.


Starry Spider Orchid (Arachnorchis stellata - formerly Caladenia stellata)

Flowers in Spring (Aug - Oct) - favours shrubby forest and Callitris woodland in well drained sandy soil.

Smallish flower; sepals have dark clubs.  Yellow flowers sometimes marked with red.  Labellum has 4 rows of calli and margins have short teeth.

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).
