Pink Sun Orchid (Thelymitra carnea)

Flowers in Spring (Sep - Nov), grows in a variety of habitats but does like some other vegetation in growing area.

This sun orchid is very reluctant to open and can be easily missed because of this.  It can grow in large colonies as seen in photo on the right. It readily hybridizes with other Thelymitra.

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

 


Rigid Spider Orchid (Arachnorchis tensa - formerly Caladenia tensa)

Flowers in Spring (Sept - Nov), favours heathy woodland with well drained soils.  Apparently confined to the Wimmera region.

Labellum has sparse calli and sepals have yellowish clubs.  The photo ruler indicates the height of this particular plant - a total of 5.25 inches (13cm).

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).
