In some cases a single ovule is attached to the bottom or top of the locule (basal or apical placentation, respectively). Often, the seeds occur inside a fleshy layer of material better known as a fruit. Hypogynous flowers are often referred to as having a superior ovary.

Perigynous flowers are often referred to as having a half-inferior ovary (or, sometimes, partially inferior or half-superior). However, as Leins & Erbar (2010) pointed out, "the classical view that the wall of the inferior ovary results from the "congenital" fusion of dorsal carpel flanks and the floral axis does not correspond to the ontogenetic processes that can actually be observed. The number of pistils usually vary with the different species of a flower. Flowers lacking a gynoecium are called staminate. This is the part of the plant that's trimmed to produce cut flowers. Draw a well-labelled diagram of L.S of a pistil of a flower showing the passage of growing of pollen tube up to its destination. [20][21][18] Therefore, "it is now increasingly acknowledged that the term 'fusion,' as applied to phylogeny (as in 'congenital fusion') is ill-advised."[22]. See more. If the hypanthium is absent, the flower is hypogynous, and the stamens, petals, and sepals are all attached to the receptacle below the gynoecium.
