(1) This, in turn was surrounded by several whorls of bracts that many homologize with petals and sepals in flowering plants.(2) Roots, stems, leaves, sepals , petals, stamens, stigmas/styles, ovaries, and seeds were collected and frozen in liquid nitrogen.(3) Fruits of this species are glabrous achenes, with sepals modified into plumose bristles and are frequently wind-dispersed.(4) The cocoa flower has five free sepals , five free petals, five staminodes, five stamens and an ovary of five united carpels.(5) The formation of organs in the four whorls of a typical eudicotyledonous flower, consisting of sepals , petals, stamens, and carpels, requires many genes for proper organ and tissue development.
