Description

There are up to four yellow and brown flowers, Шаблон:Cvt wide on slender pedicels Шаблон:Cvt long. The flowers have erect, widely-spreading, ear-like petals Шаблон:Cvt long, a dorsal sepal Шаблон:Cvt long and Шаблон:Cvt wide, and narrowly oblong, reddish-brown lateral sepals Шаблон:Cvt long. The labellum has three lobes, the lateral ones widely spreading, and the middle lobe very short and flattish with down-curved edges and a smooth yellow callus.

Taxonomy and naming

Diuris brevis was first formally described in 2016 by David Jones and Christopher French in Australian Orchid Review from specimens they collected in the Kenwick Swamp in 1997.[4] The specific epithet (brevis) means "short ", referring to the mid-lobe of the labellum.[2]

Distribution and habitat

Short-nosed donkey orchid is only known from the type location where it grows in dense, low shrubland.[1][2][3]

Conservation

Diuris brevis is listed as "Priority Two" by the Western Australian Government Department of Biodiversity, Conservation and Attractions,[1] meaning that it is poorly known and from only one or a few locations.[5]
