Diuris decrementum, commonly called the common bee orchid,[1] is a species of orchid which is endemic to the south-west of Western Australia. It is similar to the bee orchid (Diuris laxiflora) but its flowers are smaller and on a shorter flowering stem.

Description

Diuris decrementum is a tuberous, perennial herb, usually growing to a height of Шаблон:Convert with two to five leaves emerging at the base, each Шаблон:Convert long and Шаблон:Convert wide. There are up to three yellow flowers with brown blotches, Шаблон:Convert wide. The flowers have broad, ear-like petals, an erect, tapering dorsal sepal and narrow, forward-projecting lateral sepals. The labellum has three lobes, the lateral ones small and spreading, and the middle lobe elongated with a raised mid-line. Flowering occurs from late August to early November.[1][2]

Taxonomy and naming

Diuris decrementum was first formally described in 2013 by David Jones and Christopher French and the description was published in Australian Orchid Review.[3] The specific epithet (decrementum) is derived from the Latin word decrementum meaning "lessening"[4] referring to the small flowers and shorter flowering stem of this species.[1]

Distribution and habitat

The common bee orchid occurs from near Perth to the east of Esperance where it grows in a range of habitats from woodlands to soil pockets on granite outcrops.[1][5]

Conservation

Diuris decrementum is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[5]
