a style and an apical structure that receives pollen called a stigma . Ovary with stipe is called stipitate ovary. Carpel : They are components of a gynoecium. Gynoecium is made of one or more carpels.
Carpels may be distinct or connate. . . Number of carpel Unicarpellary (monocarpellary) Single carpel Example: Fabaceae Bicarpellary Two carpels Example: Rubiaceae Tricarpellary Three carpels Example: Cucurbitaceae Tetracarpellary Four carpels Example: Lamiaceae.
Multicarpellary Many carpels Example: Nymphaeceae . . . Fusion of carpels It is an important systematic character.
Apocarpous gynoecium is generally thought to be ancestral condition in Angiosperms. Figure . : Pistil Stigma Style Ovary Apocarpous A pistil contains two or more distinct carpels. Example: Annona .
Syncarpous A pistil contains two or more carpels which are connate. Example: Citrus , tomato. c0"Crqectrqwu Septum C.S. Stipe Carpels locules d0"U{pectrqwu"wpknqewnct e0"u{pectrqwu"vgvtcnqewnct Carpels locules Figure .

The walls of ovary and septa form a cavity called locule . Like that tetralocular and pentalocular ovaries are present according to the locule numbers four or five. More than one locule ovaries are called plurilocular . A.
