  • Tepals fused below, forming a tube near base; lobes usually reflexed, usually longer than tube; deciduous, cohering above when withered, circumscissile below
  • Stamens 6, arising from base of perianth tube; filaments erect and somewhat connivent or spreading, terete, smooth or rough; anthers versatile, opening by longitudinal slits
  • Ovary ovoid, obtuse; ovules many; style terete, ultimately exserted; stigma small, apical
  • Fruit an oblong-globose to globose capsule, triangular; dehiscing loculicidally
