Leucopogon

Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Prostrate shrubs to small trees. Leaves alternate, more or less coriaceous, concolorous or discolorous, the lower surface usually somewhat striate from the 3–several longitudinal (rarely palmate) nerves. Inflorescences terminal and/or axillary, with flowers solitary, or few to many in spikes; individual flowers with a bract and a pair of bracteoles immediately subtending sepals; sepals resembling bracts but larger; corolla lobes valvate in bud, finally spreading to recurved, white-bearded internally (rarely papillose or glabrous); stamens inserted just below lobes; filaments shorter than anthers; anthers with a sterile tip; ovary 2–5(–6)-locular, with 1 ovule per loculus, completely encircled by nectary of 5 lobes, style slender and terete or thickish near base and tapered upwards. Fruit a drupe.

About 230 species (with many more to be described from Western Australia), all but c. 30 endemic in Australia, the remainder extending from Malesia north-west to Indo-China, and south-east to New Zealand.

As presently understood the genus is heterogeneous. Taxa with functionally unisexual flowers have recently been placed in a new genus Acrothamnus, while a recent study suggests that some species of Leucopogon are better placed in Styphelia (Puente-Lelievre et al. 2015).
