Description:
Prostrate or decumbent to tall shrubs with woody stems; bark lightly but extensively furrowed; young stems stellate-pubescent; leaves dorsiventral, opposite and decussate, variously petiolate, nearly glabrous to tomentose with stellate vestiture; numerous oil glands but not apparent externally; volatile oil odour is species specific.
1-3 (rarely to 5) pedunculate flowers terminally developed on lateral or axillary branchlets; terminal leaf pair may act as bracts; bracteoles linear, persistent or caducous, inserted at pedicel base; calyx persistent, cup-shaped to semi-orbicular, with entire or lobed margins, remaining open or closed after anthesis; corolla with free petals in C. alba, tubular but scarcely fused in C. aemula, Sympetalous and tubular for all others, erect in 2 species, deflexed in all others; petals 4, large, 1-4 cm long, white, green, orange, red or bicoloured, more or less persistent; disk below the ovary, 8-lobed, with oil glands and nectaries; stamen filaments inserted at the disk base; the 4 opposite the petals often shorter with broad fusiform bases; anthers included to variously exserted, oblong to lanceolate, yellow-brown or rarely purple; dorsifixed and introrse; ovary superior, glabrous to tomentose; carpels 4, each with 2 ovules, placentation axile; style same length as stamens, minutely 4-lobed.
Mature fruit with 4 Basally fixed segments, apically and axially dehiscing explosively; seeds 1 or 2, 2-4 mm, endocarp cartilaginous; testa hard, brown, black or mottled; papery elaiosome present.

Taxonomic notes:
A source of variation and potential confusion within Correa is hybridisation. All taxa will hybridise and form fertile progeny when sympatric or where grown together, e.g. in cultivation-horticulture.
