Description: Herbs or shrubs.
Leaves mostly alternate, simple, margins entire, toothed or variously lobed, often with a tuft of villous hairs in axil.
Inflorescence terminal or axillary, dichasia, thyrses, racemes, subumbels, spikes or heads or flowers solitary. Flowers zygomorphic or rarely almost actinomorphic, bisexual, mostly 5-merous. Sepals 5 or 3, free or fused. Corolla yellow, white, pink, mauve [blue or brownish red], with 5 fused petals, with the tube slit on lower side, usually (except in Scaevola and Selliera) ± 2-lipped, often with auricles enclosing stamens. Stamens 5, epigynous or rarely almost hypogynous; anthers free or fused around style, 2-locular; dehiscence by longitudinal slits into the anther cylinder, so that the cylinder is filled with pollen before the style grows up. Ovary inferior to superior, 2-locular but usually incompletely so [or rarely 4-locular] or apparently 1-locular, with axile or basal placentas; ovules 1–several per loculus; style surmounted by a pollen cup or indusium which collects and exposes the pollen; stigma growing from centre of indusium.
Fruit a capsule, inferior nut or drupaceous; seeds 1–several, caruncle present or absent.
Distribution and occurrence: World: 13 genera, c. 390 species, chiefly temperate and mostly confined to Southern Hemisphere. Australia: 13 genera, c. 370 species, all States but particularly SW W.A.
