Description
Diuris laxiflora is a tuberous, perennial herb with 4 to 6 tufted leaves, each 60–150 mm long and 2–3 mm wide. The flower stem is 300–500 mm long with 1 to 6 flowers. The flowers are 10–13 mm across, are yellow with brown spots and appear from August to October.
Taxonomy and naming
The species was first described by John Lindley in 1839 and published in his "A Sketch of the Vegetation of the Swan River Colony" (1840). In ‘’The Genera and Species of Orchidaceous Plants’’ he wrote "The pedicels and ovary together are about 3 inches long, which is less than the length of the internodes. Each stem bears from 4 to 8 flowers, which seem to be dark yellow, with no spotting, but perhaps with some stains of purple."
Its specific epithet (laxiflora) is derived from the Latin words laxus meaning "loose" and flora meaning "flower". suggesting the open flower arrangement in this species.
Distribution and habitat
The species is endemic to the south western corner of Western Australia, occurring in the Avon Wheatbelt, Esperance, Geraldton Sandplains, Jarrah Forest, Mallee, Swan Coastal Plain and Warren biogeographical regions of Western Australia. It grows in sand, lateritic loam, clay and granite rock margins in winter-wet swamps.
