The petals and sepals are above the ovary; such a flower is said to have an inferior ovary, or the flower is said to be epigynous. Cross section of a tulip ovary In the flowering plants , an ovary is a part of the female reproductive organ of the flower or gynoecium .
In an epigynous flower, the stamens, petals, and sepals are attached to the hypanthium at the top of the ovary or, occasionally, the hypanthium may extend beyond the top of the ovary. Epigynous flowers are often referred to as having an inferior ovary. Plant families with epigynous flowers include orchids, asters, and evening primroses.
These three genera have been treated together taxonomically by most authors, on the basis of an inferior ovary. As the number of plant species increased, so did the taxonomic complexity. By the time Bentham and Hooker published their Genera plantarum (1862–1883) [ 35 ] ordo Amaryllideae [ 36 ] contained five tribes, and tribe Amarylleae [ 37 ...
The flower is bisexual, it contains 5 stamens, the pistil is fused of five carpels, and the ovary is inferior. A floral formula is a notation for representing the structure of particular types of flowers .
The position of the ovary varies by subfamily. The subfamilies Agapanthoideae and Allioideae have superior ovaries, while the Amaryllidoideae have inferior ovaries. The six stamens are arranged in two whorls of three, occasionally more as in Gethyllis (Amaryllidoideae, 9–18).
Ovary: Inferior - 3 fused carpels The Zingiberales are flowering plants forming one of four orders in the commelinids clade of monocots , together with its sister order, Commelinales . The order includes 68 genera and 2,600 species .
These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. [5] The family includes both epiphytes , such as Spanish moss ( Tillandsia usneoides ), and terrestrial species, such as the pineapple ( Ananas comosus ).
