Alpine Bird Orchid (Chiloglottis sp. aff. valida)

Flowers in Summer (Dec - Jan), favours Snow Gum woodland in alpine areas of Eastern Victoria.

This plant is similar to C valida except for the generally smaller flower, darker calli and is endemic to Victoria.

Pollination is by pseudo-copulation, agents being male wasps.  Each species has its own unique pollinator species.


Mountain Spider Orchid (Arachnorchis montana - formerly Caladenia montana)

Flowers in Spring/Summer (Oct - Jan), favours montane forest on moist grassy slopes.

Not often encountered and flowering seems to be stimulated by previous summer fires.  The photo ruler indicates the height of this particular plant - a total of 14.5 inches (37cm).

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).
