A cruciform arrangement occurs in Havetiopsis (Amazon district), where two pairs of sepals are followed by two pairs of petals and two pairs of stamens, the pistil forming a whorl of four carpels. In other genera a dimerous calyx and corolla are succeeded by two or three whorls of stamens and a whorl of carpels, or by numerous spirally arranged stamens. In other cases ( species of Clusia) the cruciform arrangement characterises bracteoles and calyx, while petals and stamens are arranged.
