Pimelea sulphurea is a plant in the Thymelaeaceae family. [3]

Thymelaeaceae family of plants

The Thymelaeaceae are a cosmopolitan family of flowering plants composed of 50 genera and 898 species. It was established in 1789 by Antoine Laurent de Jussieu. The Thymelaeaceae are mostly trees and shrubs, with a few vines and herbaceous plants.

Description

Pimelea sulphurea (Yellow banjine [4] ) is a small shrub from 15–60 cm high. [1] Its stems are smooth (glabrous) and its elliptic to circular leaves are opposite, and without stalks (sessile - the leaves attaching directly to the stem), and of length 2–16 mm, width 1.5–9 mm. [1] Both surfaces of the leaves are smooth and of a green to bluish green colour. [1] The inflorescence hangs down (is pendulous ), and is compact, with many flowers. [1] The yellow flowers are usually bisexual, but sometimes female only. [1] They are hairy outside and smooth inside. P. sulphurea flowers from July to November. [1]

Sessility (botany)

In botany, sessility is a characteristic of plant parts that have no stalk. Flowers or leaves are borne directly from the stem or peduncle, and thus lack a petiole or pedicel. The leaves of most monocotyledons lack petioles.

Habitat

It usually grows on sand, within woodland or shrubland. [1]

Distribution

The species occurs in the south-west of Western Australia, [1] [5] in the IBRA regions of Avon Wheatbelt, Coolgardie, Esperance Plains, Geraldton Sandplains, Jarrah Forest, Mallee, and the Swan Coastal Plain. [4]

Western Australia State in Australia

Western Australia is a state occupying the entire western third of Australia. It is bounded by the Indian Ocean to the north and west, and the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of 2,529,875 square kilometres, and the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. The state has about 2.6 million inhabitants – around 11 percent of the national total – of whom the vast majority live in the south-west corner, 79 per cent of the population living in the Perth area, leaving the remainder of the state sparsely populated.

Avon Wheatbelt Bioregion

The Avon Wheatbelt is an Australian bioregion in Western Australia and part of the larger Southwest Australia savanna ecoregion.

Coolgardie (biogeographic region) Ecoregion (WWF)

Coolgardie is an Australian bioregion and a World Wildlife Fund ecoregion consisting of an area of low hills and plains of infertile sandy soil in Western Australia.

Taxonomy

The species was described by C.D.F. Meisner in 1848. [6] [2] In 1852, Walpers assigned it to Meyer's genus of Calyptrostegia (now considered a synonym of Pimelea ) [7] thereby giving it the name, Calyptrostegia sulphurea. [8] [9] In 1891, Otto Kuntze redescribed Pimelea as being the genus Banksia and hence gave it (incorrectly) the name Banksia sulfurea. [10] [11]

Carl Anton von Meyer was a German, Russified botanist and explorer.
