A flower has four series on thalamus from base to top: calyx, corolla, androecium (stamens) and Gynoecium (Carpels with ovary at base). Naturally ovary is superior to all other whorls. flower hypogynous; during the course of evolution ovary becomes inferior due to two reasons: 1. calyx fuses with ovary (consequently corolla also) so that ovary (with ovules inside) appears lower than other whorls (consequently inferior): flower epigynous. 2. There is axial invagination of thalamus so that ovary (and carpels) lie at bottom of the depression (ovary semi-inferior); flower pergynous
