Common Name
Tall Donkey Orchid

Description
The Tall Donkey Orchid is endemic to Western Australia. As its name indicates it is a fairly large Diuris species growing to about a metre in height. The flowers are yellow, with typical ear-shaped lateral petals. The labellum and dorsal sepal are mostly yellow with some darker markings near the centre of the flower. Three to eight flowers are produced in a cluster, with each individual flower about 3 cm across. Flowering is in late spring and early summer from October to January. The plant forms tubers and can grow in dense colonies. It responds to fire by increased flowering and increased spread of the colony.
