Hibbertia spicata is a species of flowering plant in the family Dilleniaceae and is endemic to the west of Western Australia. It is a low, erect to spreading shrub with scattered linear leaves with the edges rolled under and yellow flowers with six or seven stamens on one side of two softly-hairy carpels, and a larger number of staminodes.
Description
Hibbertia spicata is an erect to spreading shrub that typically grows to a height of up to Шаблон:Cvt, its older stems covered with papery bark. The leaves are linear, mostly Шаблон:Cvt long and Шаблон:Cvt wide with the edges rolled under, sometimes obscuring the hairy lower surface. The flowers are crowded along a cincinnus of eight to fourteen flowers, all but the lowest with two bracts at the base. The five sepals are egg-shaped, Шаблон:Cvt long and the five petals are yellow, Шаблон:Cvt long and egg-shaped with the narrower end towards the base. There are six or seven stamens fused at the base on one side of the two softly-hairy carpels, and ten to fourteen staminodes arranged around the carpels, each carpel with two ovules. Flowering occurs from April to October.[1][2]
Taxonomy
Hibbertia spicata was first formally described in 1860 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae from specimens collected at Port Gregory by Pemberton Walcott and Augustus Frederick Oldfield.[3][4] The specific epithet (spicata) means "spicate".[5]
In 1984, Judith Roderick Wheeler described two subspecies and the names are accepted by the Australian Plant Census:
- Hibbertia spicata subsp. leptotheca K.R.Thiele[6] has few, or no staminodes, and the outer two sepals more or less glabrous;[1]
- Hibbertia spicata F.Muell. subsp. spicata[7] has six to twelve staminodes and the outer two sepals are hairy.[1]
Distribution and habitat
Subspecies leptotheca grows on near-coastal limestone between Lancelin and the Yalgorup National Park and subspecies spicata grows in a variety of soils in heathland on the Darling Range.[1][8]
