Pretty Leek Orchid (Prasophyllum sp. aff. diversiflorum)

Flowers in Spring(Oct - Nov), favours grassland habitats on basalt soils.

Flowers are green with some brown tones and white labellum.  Lateral sepals are divergent; sepals incurved.  This orchid is known from near Orford and should be considered endangered because of loss of habitat.  The photo ruler indicates the height of this particular plant - at total of 16 inches (41cm).

Bees and wasps are reported to be main pollinators of this genus although syrphiid flies and ants are also frequent visitors.


Green-comb Spider Orchid (Arachnorchis dilatata - formerly Caladenia dilatata)

Flowers in Spring/Summer (Nov - Jan), favours coastal heathlands and woodland in well-drained soils.

Late flowering greencomb with yellow-brown clubs, larger on sepals.  Leaf is long, narrow and present with flower.  Lateral sepal and petals are deflexed   The photo ruler indicates the height of this particular plant - a total of 10 inches (25cm).

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).
