Darwinia polychroma, commonly known as harlequin bell,[1] is a species of flowering plant in the myrtle family Myrtaceae and is endemic to Western Australia. It has linear leaves and drooping flowers surrounded by yellowish green, green and red bracts.
Description
Darwinia polychroma is a spreading shrub up to Шаблон:Cvt high and Шаблон:Cvt wide when mature, with many old, grey, leafless woody stems on the ground, but is an erect shrub when young. The leaves are densely crowded on the ends of branches, and are linear, triangular in cross-section, Шаблон:Cvt long and Шаблон:Cvt wide on a petiole about Шаблон:Cvt long. The flowers are arranged in drooping groups surrounded by several overlapping rows of yellowish green, green and red bracts Шаблон:Cvt long. Each flower has two boat-shaped to egg-shaped bracteoles at the base. The floral tube is yellowish green, about Шаблон:Cvt long, the sepal lobes about Шаблон:Cvt long, the petals Шаблон:Cvt long and there are 10 stamens and 10 staminodes. Flowering mainly occurs from July to September.[1][2][3]
Taxonomy
Darwinia polychroma was first formally described in 2009 by Gregory John Keighery in the journal Nuytsia from specimens collected near Carnamah in 1995.[3][4] The specific epithet (polychroma) means "many-colours", referring to the involucral bracts.[3]
Distribution and habitat
Harlequin bell grows in shrubland, and is confined to a few road and rail verges in the Carnamah area, in a range of about Шаблон:Convert, although prior to 1929 it had a wider distribution. It is found amongst open low scrub or shrubland with Melaleuca species, Acacia ligulata, mallee (Eucalyptus species) and Exocarpos species growing in yellow loamy sand over laterite. Three populations occur on road or railway reserves with one on private property.[1][2][3] Its range is over approximately Шаблон:Convert with three populations occurring on road or railway reserves with one on private property. The total populations is less than 200 plants.[1]
Conservation status
This darwinia is listed as "endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and as "threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions,[2] meaning that it is in danger of extinction.[5]
