There are up to four pale yellow flowers with brown markings, Шаблон:Cvt wide. The flowers have erect, ear-like petals Шаблон:Cvt long, an egg-shaped dorsal sepal Шаблон:Cvt long and Шаблон:Cvt wide, and narrowly oblong lateral sepals Шаблон:Cvt long.

Taxonomy and naming

Diuris brachyscapa was first formally described in 2016 by David Jones and Christopher French in Australian Orchid Review from specimens collected by French near Kweda in 1996.[4] The specific epithet (brachyscapa) means "short stem", referring to the short habit of this species compared to D. corymbosa.[2]

Distribution and habitat

Western wheatbelt donkey orchid grows in woodland, and on and around granite outcrops between the Albany and Great Eastern Highways, Katanning and Ravensthorpe in the Avon Wheatbelt, Esperance Plains, Jarrah Forest and Mallee bioregions of south-western Western Australia.[1][2][3]

Conservation

Diuris brachyscapa is classified as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.[1]
