Subfamily Epacridoideae

Description: Small shrubs; branchlets finely pubescent to hirsute.

Leaves crowded, usually linear, lanceolate or oblong, discolorous, the lower surface dull or glaucous and shallowly or deeply striate-veined, and usually with a pungent tip; petiole short.

Flowers small, in sessile or shortly pedunculate spikes, axillary or on the old wood below the leaves; each flower subtended by 1 bract and 2 bracteoles. Sepals 5, ovate to ± circular, obtuse and glabrous except for ciliolate margins. Corolla tube campanulate to cylindrical, often somewhat inflated, with 5 tufts of hairs spreading across the throat; lobes valvate in bud, spreading in open flower, each with an erect tuft of hairs near the tip. Stamens with short filaments inserted at the throat; anthers half to fully exserted, obvious below the lobes outside. Nectary annular. Ovary globose, usually 2–7-locular with 1 ovule per loculus; style short, not exserted; stigma lobed.

Fruit usually flat-topped.
