Belongs within: Boronieae.

Boronia is an Australian genus of shrubs (more rarely small trees or herbs) bearing flowers with pyramidally arranged stamens and fruits composed of basally fused cocci. A small number of species are native to New Caledonia. Several species are popular cultivated plants, grown for their fragrant flowers.

Characters (from New South Wales Flora Online): Shrubs or rarely small trees or rarely herbs, glabrous or with simple or stellate hairs, unarmed. Leaves opposite (or rarely subopposite or whorled), simple or 1-foliolate, palmately 3-foliolate or pinnately 3–19[–41]-foliolate or bipinnate; leaflets with margins entire or toothed, or rarely 3-lobed; lateral leaflets opposite. Inflorescences axillary or terminal, cymose or paniculate or reduced to single flowers. Flowers bisexual, 4- or rarely 5-merous. Sepals usually 4, free. Petals usually 4, valvate or imbricate, free, persistent or not persistent in fruit. Stamens mostly 8, free, erect or pyramidally arranged. Carpels 4 (or rarely 5), more or less free, lacking a sterile apex; styles fused, arising terminally or subterminally from the carpels; stigma scarcely differentiated from style or capitate or grossly swollen and almost sessile; ovules 2 in each carpel. Fruit of 1–4 cocci; cocci not transversely ridged, with rounded apices; seeds released forcibly from dehiscing cocci, dull or shiny, black.
