It has between two or three grass-like leaves of different lengths, and a flowering stem with up to five pale yellow to butter yellow flowers with reddish brown or purple marks and patterns, and leopard-like spots on the back.
Description
Diuris leopardina is a tuberous, terrestrial herb with two or three erect, grass-like, linear leaves Шаблон:Cvt long and of different lengths. Up to five pale yellow to butter yellow flowers Шаблон:Cvt in diameter are borne on a flowering stem usually Шаблон:Cvt tall. The dorsal sepal is oblong, Шаблон:Cvt long and Шаблон:Cvt wide, the lateral sepals linear, purplish brown with green edges, Шаблон:Cvt long and about Шаблон:Cvt wide. The petals are more or less erect, broadly egg-shaped to round, Шаблон:Cvt long and Шаблон:Cvt wide. The labellum has three lobes, the middle lobe oblong, Шаблон:Cvt long and Шаблон:Cvt wide and the side lobes spread widely, pressed against the dorsal sepal, Шаблон:Cvt long and Шаблон:Cvt wide. The callus consists of two purplish ridges. Flowering occurs from late September to November.[1]
This donkey orchid is similar to Diuris pardina but has fewer, taller flowers and a later flowering period.[1]
Taxonomy and naming
Diuris leopardina was first formally described in 2017 by David Jones and Robert Bates in Australian Orchid Review from specimens collected near the Penola to Duradong road in 1963.[1][2] The specific epithet (leopardina) means "marked like a leopard", referring to the spots on the back of the flowers and large patches on the dorsal sepal.[1]
Distribution and habitat
This species of orchid grows in open forest on the plains of south-eastern South Australia and nearby areas of Victoria.[1]
