Arbres , arbustes, ou lianes, rarement herbacées. Feuilles habituellement opposées, composées palmées ou pennées, parfois simples, foliole terminale souvent remplacée par une vrille chez les lianes. Inflorescence terminale ou axillaire, en panicule ou racème, parfois réduite à un fascicule ou à une simple fleur. Fleurs avec le calice synpétale, habituellement plus ou moins cupulaire, tronqué à variablement lobé ou fendu comme une spathe. Corolle synpétale avec un tube visible et 5 lobes habituellement imbriqués. Étamines insérées sur le tube de la corolle, didynames, habituellement 4, rarement 2 ou 5, un staminode postérieur ordinairement présent, anthères à 1 ou 2 thèques, celles-ci habituellement divergentes ou divariquées et accrochées contre le côté adaxial du tube de la corolle, filets minces. Ovaire supère, 1 ou (habituellement) 2 loges, ovules nombreux, attachés à quatre arêtes placentaires, celles-ci axiles dans les ovaires biloculaires et pariétales dans les ovaires uniloculaires (une seule crête placentaire dans chaque loge dans quelques espèces de Schlegelia MIQ.), un style mince, stigmate bilamellé. Disque nectarifère normalement visible, parfois manquant. Fruit en capsule avec déhiscence perpendiculaire ou parallèle au septum ou en baie ou en peponide (calebasse). Graines sans endosperme, quelquefois aplaties, habituellement ailées, à cotylédons foliacés.
