Leucopogon marginatusW.Fitzg.

Styphelia marginata, commonly known as thick-margined leucopogon, [1] is a species of flowering plant in the heath family Ericaceae and is endemic to the south-west of Western Australia. It is a dwarf shrub with lance-shaped leaves and white, tube-shaped flowers.

Description

Styphelia marginata is a dwarf shrub that typically grows to a height of 40–60 cm (16–24 in) and has glabrous new growth. The leaves are lance-shaped, 4–6 mm (0.16–0.24 in) long with a short petiole, and are sharply pointed. The leaves have a stem-clasping base and membraneous edges. The flowers are white, arranged singly or in groups of up to 3 in upper leaf axils with a bracteole about one-third the length of the sepals. The sepals are broadly lance-shaped, 2.0–2.6 mm (0.079–0.102 in) long. The petals are joined at the base, forming a tube slightly longer than the sepals, and have 5 bearded lobes but with glabrous tips. The style is slightly longer than the petal tube. [1] [4]

Taxonomy

This species was first formally described in 1904 by William Vincent Fitzgerald who gave it the name Leucopogon marginatus in the Journal of the West Australian Natural History Society from specimens he collected on sand plains near Arrino in 1903. [4] [5]

In 2020, Hislop, Crayn and Puente-Lel. transferred L. marginatus to Styphelia as S. marginata in the journal Australian Systematic Botany . [6] [7] As at February 2023, the name Styphelia marginata is accepted by the Herbarium of Western Australia [8] and by Plants of the World Online. [3] The Australian Plant Census list S. marginata as a synonym as L. marginatus. [9]

The specific epithet (marginata) means "furnished with a border", referring to the margins of the leaves. [10]

Distribution

This species occurs in the Avon Wheatbelt and Geraldton Sandplains bioregions of south-western Western Australia. [8]

Conservation status

Leucopogon marginatus is listed as "endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 [1] and a recovery plan has been prepared. [11] Styphelia marginata is classified as "Threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions, [8] meaning that it is in danger of extinction. [12] The main threats to the species include inappropriate fire regimes, grazing by livestock and weed invasion. [11]

<i>Leucopogon</i> Genus of flowering plants

Leucopogon is a genus of about 150-160 species of shrubs or small trees in the family Ericaceae, in the section of that family formerly treated as the separate family Epacridaceae. They are native to Australia, New Zealand, New Caledonia, the western Pacific Islands and Malaysia, with the greatest species diversity in southeastern Australia. Plants in this genus have leaves with a few more or less parallel veins, and tube-shaped flowers usually with a white beard inside.

<i>Styphelia planifolia</i> Species of shrub

Styphelia planifolia is a small shrub in the family Ericaceae native to Western Australia. It was first described as Leucopogon planifolius in 1845 by Otto Wilhelm Sonder, but moved to the genus, Styphelia, by Hermann Sleumer in 1963. Until 2020, the name Leucopogon planifolius was the name accepted by the Council of Heads of Australasian Herbaria, but the Herbarium of Western Australia now accepts the name Styphelia planifolia based on the phylogenetic studies of Crayn and others.

<i>Styphelia conostephioides</i> Species of flowering plant

Styphelia conostephioides is a plant in the family Ericaceae native to Western Australia. It was first described in 1839 as Leucopogon conostephioides by Augustin Pyramus de Candolle. In 1867 Ferdinand von Mueller transferred it to the genus, Styphelia, but the accepted name continued to be Leucopogon conostephioides. However in 2020, with a publication concerning the phylogeny of Styphelia by Crayn and others, the name Styphelia conostephioides was accepted by the Herbarium of Western Australia.

Styphelia crassifolia is a plant in the family Ericaceae native to Western Australia. It was first described in 1845 as Leucopogon crassifolius by Otto Wilhelm Sonder. In 1867 Ferdinand von Mueller transferred it to the genus, Styphelia, but the accepted name continued to be Leucopogon crassifolius. However, in 2020, with a publication concerning the phylogeny of Styphelia by Crayn and others, the name Styphelia crassifolia was accepted by the Herbarium of Western Australia.

<i>Coleanthera</i> Genus of flowering plants

Coleanthera is a plant genus in the family Ericaceae. The genus is endemic to Western Australia, and is currently accepted by Plants of the World online, and the Council of Heads of Australasian Herbaria, but not by the Western Australian Herbarium, where it has been subsumed into the genus, Styphelia, for the phylogenetic reasons given by Darren M. Crayn, Michael Hislop and Caroline Puente-Lelièvre.

<i>Styphelia coelophylla</i> Species of flowering plant

Styphelia coelophylla is a plant in the family Ericaceae native to Western Australia. It was first described as Leucopogon coelophyllus in 1839 by Allan Cunningham, but based on the phylogenetic studies of Darren Crayn, Michael Hislop and Caroline Puente-Lelièvre in 2020 it was moved to the genus, Styphelia, and Styphelia coelophylla is the name accepted by the WA herbarium.
