Leucopogon

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.

Description

Plants in the genus Leucopogon range from prostrate shrubs to small trees. The leaves are arranged alternately and usually have about three, more or less parallel veins visible on the lower surface. The flowers are arranged in leaf axils or on the ends of branchlets either singly or in spikes of a few to many flowers. There is a single egg-shaped to circular bract and a pair of similar bracteoles at the base of each flower immediately below the five sepals. The sepals are similar to the bracts but larger. The petals are fused to form a tube with the five petal tips rolled back or spreading, usually with a beard of white hairs inside. The stamens are attached to the tube near its tip and have a short filament and the tip of the style is thin. The fruit is a drupe.

Taxonomy and naming

The genus Leucopogon was first formally described in 1810 by Robert Brown in his Prodromus.[2][3]

In 2005, following cladistic analysis, in a paper published in Australian Systematic Botany, Christopher John Quinn and others transferred some species previously known as species of Leucopogon to other genera, including Androstoma Hook.f., Acrotriche R.Br., Acrothamnus Quinn and Agiortia Quinn. These species include the former L. colensoi, L. milliganii, L. maccraei, L. montanus. These, and other changes proposed have been accepted by the Australian Plant Census ("APC") but not the change of L. melaleucoides to Acrothamnus melaleucoides.[4][5]

Further molecular phylogenetic analysis of Styphelia and related genera by Crayn and others in 2018 have led to further proposed changes, not yet assessed by the APC as at April 2020. These changes include moving 75 species of Leucopogon to Styphelia.[6]

The genus name, Leucopogon is derived from ancient Greek words meaning "white" and "beard", referring to the petal tube.[7][8]

Species list

The following is a list of species accepted by the Australian Plant Census as at April 2020 and by the New Zealand Plant Conservation Network for species occurring in New Zealand. There is a proposal to move the species marked with an asterisk to the genus Styphelia.[6][9][10]
