All three of these structures combined are called the pistil. Surrounding the style can be one or more filaments each with an anther on the top which contains the pollen. Around all of those structures are the petals, when combined are the corolla. At the base of the corolla, there are green leaves called calyx.directly under the ovary is the peduncle or stem.
