    Inflorescences of unilateral (scorpioid) fasciculate to spiciform cymes, axillary and/or terminal, often compounded into a dense synflorescence, rarely a dichasial thyrse or flowers solitary; bract pairs equal to dimorphic, free, sterile bracts in unilateral cymes typically imbricate and subtending flowers, fertile bracts and bracteoles usually adpressed to calyx; bracteoles paired, (sub)equal, free.

    Stamens 4, didynamous, filaments arising from near base of corolla throat; anterior pair of stamens longer, bithecous, thecae at an equal height or offset; posterior pair shorter, monothecous or bithecous.
    Ovary bilocular, 1 or 2 ovules per locule; style filiform; stigma capitate-bilobed or one lobe expanded and spoon-shaped.
    Capsule compressed, 2-seeded, face then ovate, or 4-seeded, face then oblong-elliptic, sometimes with a short sterile apical beak, placental base inelastic.
