White donkey orchid
This deciduous terrestrial orchid grows in grassy woodland and heath along the coast.
Its grass like leaves grow to 40 cm. The flower stem grows to 40 mm tall with up to 7, 20 mm white flowers with lilac blotches. The area between the labellum callus ridges is yellow.
This orchid is identified by the very pale colour and divergent petals which are only half as wide as their length. It is unlikely to be confused with any other orchid around Brisbane.
