The perianth segments and stamen (s) may be attached to the pistil(s) in one of three ways: Hypogynous positioned below the pistil Perigynous positioned around the pistil Epigynous positioned above the pistil In Cactaceae, the perianth form an intergrading series of segment variously known as, tepals, sepaloids and petaloids.
