Genus Leucopogon Family Ericaceae
Subfamily Epacridoideae

Description: Shrubs or [small trees]; branches erect to spreading, glabrous to pubescent.

Leaves erect to reflexed, aristate or with a callous tip, usually concolorous; lamina glabrous or pubescent, lower surface striate, margins entire or ciliate to finely toothed; sessile or shortly petiolate.

Flowers in solitary or clustered spikes, each flower subtended by a single bract and 2 bracteoles; peduncles usually pubescent; bracts and bracteoles ovate to circular, glabrous except for ciliolate margins. Sepals similar to bracts. Corolla tube often shorter than lobes, glabrous, or minutely pubescent inside near the throat or with lobe hairs deflexed into tube; lobes valvate in bud, erect to spreading, rarely reflexed in the open flower, white-bearded inside. Stamens inserted at the throat; filaments slender, terete; anthers usually partly enclosed in the tube, with or without a paler sterile tip. Ovary usually 2–5-locular, with 1 ovule per loculus; style usually glabrous, stigma lobed; nectary annular or in 5 scales.

Fruit a drupe.

Distribution and occurrence: World: c. 230 species, Australia, Malaysia, Indo-China, New Caledonia, Pacific & New Zealand. Australia: c. 200 species (most species endemic), all States.
