Leaves alternate, simple, entire or somewhat lobed.
Morphology Reproductive morphology Flowers
Flowers bibracteolate, in spikes or more generally dense to lax terminal and axillary bracteate thyrses (the uppermost frequently forming a panicle), lateral cymes lax to dense and forming lateral clusters and the inflorescence then spiciform.
Morphology Reproductive morphology Flowers Perianth
Perianth segments 5, free, all more or less equal.
Morphology Reproductive morphology Flowers Androecium
Stamens 5, the filaments fused below into a short cup, the free portions deltoid below and narrow above or more or less swollen below; pseudostaminodes absent but minute blunt intermediate teeth occasionally found; anthers bilocular.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary with few to numerous ovules (one or two species occasionally with solitary ovules in some ovaries); style distinct and elongate to almost obsolete; stigmas 2–3, circular to filiform.
Morphology Reproductive morphology Fruits
Capsule circumcissile, sometimes thickened at the apex.
