Description
Goodenia watsonii is perennial herb that typically grows to a height of Шаблон:Cvt with a thick stem. It has egg-shaped to elliptic leaves Шаблон:Cvt long, Шаблон:Cvt wide at the base of the plant and sometimes with toothed edges. The flowers are arranged in thyrses up to Шаблон:Cvt long on a peduncle up to Шаблон:Cvt long, each flower on a pedicel Шаблон:Cvt long with linear bracts up to Шаблон:Cvt long and shorter bracteoles. The sepals are narrow egg-shaped, Шаблон:Cvt long, the corolla white, cream-coloured or bluish, Шаблон:Cvt long. The corolla lobes are Шаблон:Cvt long with wings about Шаблон:Cvt wide. Flowering occurs from October to February and the fruit is a more or less spherical capsule Шаблон:Cvt in diameter.[1][2]
Taxonomy and naming
Goodenia watsonii was first formally described in 1893 by Ferdinand von Mueller and Ralph Tate in Botanisches Centralblatt from material collected by Richard Helms "at Gnarlbine" during the Elder Exploring Expedition.[3][4] The specific epithet (watsonii) honours "Professor Watson, of the Adelaide University.[4]
In 1990, Roger Charles Carolin described two subspecies in the journal Telopea and the names are accepted by the Australian Plant Census:[5]
- Goodenia watsonii subsp. glandulosa Carolin[6] has the peduncles, pedicels ovary and parts of the petals covered with soft glandular hairs, and a bluish corolla with a yellow centre, or whitish;[5][7][8]
- Goodenia watsonii F.Muell. & Tate subsp. watsonii[9] has most glabrous flower parts and a white corolla.[5][10][11]
Distribution and habitat
This goodenia grows in heath in the south-west of Western Australia.[2][1] Subspecies glandulosa is restricteed to areas between Lake Grace and Hyden.[10][11]
Conservation status
Both subspecies of G. watsonii are classed as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[8][11]
