Feuilles alternes ou rarement (sub)verticillées, simples, pétiolées; stipules absentes; limbe entier ou rarement denté ou lobé, souvent coriace, penninervé. Inflorescence: panicule ou corymbe ombelliforme ou fleurs solitaires, terminale ou axillaire. Fleurs bisexuées ou fonctionnellement unisexuées, actinomorphes, 5-mères (sauf l'ovaire), à 2 bractéoles; sépales libres ou un peu connés, imbriqués, caducs; pétales souvent soudés en tube à la base, imbriqués; étamines épisépales, anthères à 2 loges, déhiscentes par fentes ou pores, dorsifixes à basifixes; ovaire supère, 2(-5)-carpellaire mais généralement uniloculaire, placentas pariétaux et portant chacun 2 rangées d'ovules; style 1 à stigmate capité ou lobé. Fruits: capsules à déhiscence valvaire, ou parfois baies. Graines nombreuses, souvent plongées dans une pulpe résineuse, à testa mince et lisse; albumen abondant; embryon excentré.

Inflorescences umbellate, corymbose, paniculate, or a solitary flower, bracteate and bracteolate. Flowers usually bisexual, sometimes polygamous, actinomorphic, rarely zygomorphic, usually 5-merous (except ovary). Sepals usually free or slightly connate. Petals free or connate, white, yellow, blue, or red. Stamens opposite sepals; filament filiform; anther basifixed or dorsifixed, 2-loculed, dehiscing longitudinally or by pores.
