Шаблон:Short description Шаблон:Speciesbox
Goodenia scapigera, commonly known as white goodenia,[1] is a species of flowering plant in the family Goodeniaceae and is endemic to the south-west of Western Australia. It is an erect, perennial herb or shrub with linear to narrow egg-shaped leaves clustered near the ends of the stems, and thyrses of white flowers with purplish spots.
Description
Goodenia scapigera is an erect, perennial herb or shrub that typically grows to a height of Шаблон:Cvt and is glabrous. The leaves are linear to narrow egg-shaped with the narrower end towards the base, more or less clustered at the ends of the stems, Шаблон:Cvt long and Шаблон:Cvt wide, sometimes with toothed edges. The flowers are arranged in thyrses up to Шаблон:Cvt long, with linear bracts about Шаблон:Cvt long and linear bracteoles about Шаблон:Cvt long. Each flower is on a pedicel Шаблон:Cvt long with linear to triangular sepals Шаблон:Cvt long. The petals are white with purplish spots near the base, Шаблон:Cvt long, the lower lobes of the corolla Шаблон:Cvt long with wings about Шаблон:Cvt wide. Flowering mainly occurs from September to January and the fruit is an oval to elliptical capsule Шаблон:Cvt long.[1][2]
Taxonomy and naming
Goodenia scapigera was first formally described in 1810 by Robert Brown in his Prodromus Florae Novae Hollandiae et Insulae Van Diemen.[3][4] The specific epithet (scapigera) means "bearing a flower stalk".[5]
In 2000, Leigh William Sage described two subspecies and the names are accepted by the Australian Plant Census:[6]
- Goodenia scapigera subsp. graniticola L.W.Sage[7] differs from the autonym in having leaves that are in clusters, linear, not toothed, and up to Шаблон:Cvt wide;[6][8]
- Goodenia scapigera R.Br. subsp. scapigera L.W.Sage[9] (the autonym) has leaves not clustered, linear to narrow egg-shaped, sometimes toothed and Шаблон:Cvt wide.[6][10]
Distribution and habitat
This goodenia usually grows in sandy soil in woodland or heath and is widespread in the Avon Wheatbelt, Coolgardie, Esperance Plains, Jarrah Forest, Mallee and Swan Coastal Plain biogeographic regions in the south west of Western Australia. Subspecies graniticola has a more restricted distribution, growing in heath in granitic soil near Peak Charles National Park.[1][2][6][8][10]
Conservation status
Goodenia scapigera subsp. scapigera is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife, but subsp. graniticola is classified as "Priority Two" by the Western Australian Government Department of Parks and Wildlife[1] meaning that it is poorly known and from only one or a few locations.[8][11]
