    Brassicaceae

  • Life FormPlants usually herbaceous, sometimes woody.Flowers bisexual and mostly regular. Inflorescence typically a raceme.Leaves alternate, simple or divided. Major leaves often in basal rosette.

    Six stamens, usually with four long and two short filaments. Superior ovary on prolonged receptacle (gynophore); two carpels that form two-chambered capsule-like fruit with persistent central dividerFour distinct sepals and petals. Petals have claw at base and form cross when fully open. Stems and LeavesPerianthFlowers and InflorescenceReproductive StructuresFruitSilique, silicle or capsule.Brassicaceae
