Diuris magnifica, commonly called the large pansy orchid[1] is a species of orchid which is endemic to the south-west of Western Australia. It has large, colourful flowers and is common in a narrow range near the coast around Perth, often occurring with the similar but smaller Diuris corymbosa.
Description
Diuris magnifica is a tuberous, perennial herb, usually growing to a height of Шаблон:Convert. Two or three leaves emerge at the base, each leaf Шаблон:Convert long, Шаблон:Convert wide and folded lengthwise. There are between three and nine golden-yellow and purple flowers Шаблон:Convert long and Шаблон:Convert wide. The dorsal sepal is egg-shaped, Шаблон:Convert long and Шаблон:Convert wide and curves upwards. The lateral sepals are linear to lance-shaped, Шаблон:Convert long, about Шаблон:Convert wide, turned downwards and usually crossed. The petals are erect with an egg-shaped blade Шаблон:Convert long and Шаблон:Convert wide on a purplish-brown stalk Шаблон:Convert long. The labellum is mauve or purple with some yellow markings, Шаблон:Convert long and has three lobes. The centre lobe is wedge-shaped, Шаблон:Convert long and Шаблон:Convert wide and the side lobes are Шаблон:Convert long and Шаблон:Convert wide. There is a single yellow, ridged callus Шаблон:Convert long in the mid-line of the labellum. The species is similar to several other Diuris including D. corymbosa and D. amplissima but is distinguished from them by its size, flowering period and distribution. Flowering occurs from late August to October.[1][2][3][4]
Taxonomy and naming
Diuris magnifica was first formally described in 1991 by David Jones from a specimen collected in a reserve near Kwinana and the description was published in Australian Orchid Review.[5][2] The specific epithet (magnifica) is a Latin word meaning "noble", "eminent" or "splendid"[6] referring to the large, colourful flowers of this orchid.[2]
Distribution and habitat
The large pansy orchid is common in near coastal shrubland and woodland between Lancelin and Mandurah in the Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain biogeographic regions. At the northern end of its distribution, this species hybridises with the as yet undescribed Arrowsmith pansy orchid (Diuris sp. 'Eneabba') and in the south with D. corymbosa.[3][4][7]
Conservation
Diuris magnifica is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[7]
