Шаблон:Short description Шаблон:Speciesbox
Hibbertia glomerata is a species of flowering plant in the family Dilleniaceae and is endemic to the south-west of Western Australia. It is a much-branched shrub with mostly oblong or egg-shaped to elliptic leaves and yellow flowers borne on the ends of short side shoots, with nine to twelve stamens, sometimes in groups of three, arranged around the three carpels.
Description
Hibbertia glomerata is a much-branched shrub that typically grows to a height of Шаблон:Cvt, the branchlets with prominent leaf scars. The leaves are spirally arranged and mostly oblong or egg-shaped to elliptic, Шаблон:Cvt long, Шаблон:Cvt wide and more or less glabrous. The flowers are arranged singly on short side-shoots and are Шаблон:Cvt wide and sessile, usually with three egg-shaped bracts Шаблон:Cvt long at the base of the flower. The five sepals are joined at the base, elliptic and Шаблон:Cvt long and the five petals are yellow, egg-shaped with the narrower end towards the base and Шаблон:Cvt long with a notch at the tip. There are ten to twelve stamens, either free from each other or in groups of three, arranged around the three glabrous carpels, each carpel containing one ovule.[1][2]
Taxonomy
Hibbertia glomerata was first formally described in 1863 by George Bentham in Flora Australiensis from specimens collected by James Drummond from the Swan River Colony.[3][4] The specific epithet (glomerata) means"collected into heads", referring to the flowers.[5]
In 2002, Judy Wheeler described four subspecies and the names are accepted by the Australian Plant Census:
- Hibbertia glomerata subsp. darlingensis J.R.Wheeler[6] has eleven stamens, nine of them in three groups, all leaves oblong to elliptic, glabrous and Шаблон:Cvt wide and flowers mainly from August to October;[1]
- Hibbertia glomerata subsp. ginginensis J.R.Wheeler[7] has eleven stamens, nine of them in three groups, some leaves oblong to elliptic, glabrous and Шаблон:Cvt wide, floral leaves Шаблон:Cvt wide and flowers from July to September;[1]
- Hibbertia glomerata Benth. subsp. glomerata[8] has ten to twelve stamens mostly free from each other, some leaves oblong to elliptic, glabrous and Шаблон:Cvt wide and floral leaves egg-shaped to elliptic and usually with wavy edges. and mostly flowers from September to November;[1]
- Hibbertia glomerata subsp. wandoo J.R.Wheeler[9] has ten to twelve stamens mostly free from each other, all leaves are narrow egg-shaped with the narrower end towards the base, the outer sepals shorter than the inner sepals, and mostly flowers from August to October.[1]
Distribution and habitat
This hibbertia grows occurs in the Jarrah Forest and Swan Coastal Plain biogeographic regions of south-western Western Australia.[1][2] Subspecies darlingensis is found in forest and woodland, sometimes on roadside reserves, on the Darling Scarp, mainly near Perth.[1][10] Subspecies ginginensis occurs in woodland and forest mainly on roadsides near Gingin.[1][11] The autonym glomerata is found in a variety of habitats in the south-west of Western Australia[1][12] and subsp. wandoo is restricted to an area near Beverley where it grows in wandoo woodland.[1][13]
Conservation status
Hibbertia glomerata is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife,[2] but subsp. ginginensis is classified as "Priority Two"[11] meaning that it is poorly known and from only one or a few locations and subsp. wandoo as "Priority Three"[13] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[14]
