Description

Diuris is a large genus of terrestrial orchids, which are commonly called 'donkey orchids'. Oaklands Diuris is related to the Victorian species D. fragrantissima but differs from it in a number of characteristics: it is much more robust and has larger leaves; the flower-stem is to 50 cm tall, compared to 20 cm; there are up to nine flowers per flower-stem, compared to six; the flowers are slightly fragrant compared to being intensely fragrant with a strong spicy scent. It also has longer lateral sepals and a larger column. Unlike many species in the genus, which are yellow (often in combination with purple) in colour, the flowers of Oaklands Diuris are white and purple.
