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.
An inferior ovary lies below the attachment of other floral parts. A pome is a type of fleshy fruit that is often cited as an example, but close inspection of some pomes (such as Pyracantha) will show that it is really a half-inferior ovary. Flowers with inferior ovaries are termed epigynous.
The flowers have three stamens and a gynoecium of three united carpels and an inferior ovary, three locules and axile placentation with fruit that is a loculicidal capsule. [2] Crocus is an acaulescent (lacking a visible lower stem above ground) diminutive seasonal cormous (growing from corms) herbaceous perennial geophytic genus. [3]
Close-up of a Schlumbergera flower, showing part of the gynoecium (specifically the stigma and part of the style) and the stamens that surround it. Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction.
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 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).
Male flowers have three stamens that are connected to a single filament column. The anthers form a globose head. The pollen is produced in S-shaped thecae. Female flowers have an inferior ovary consisting of three carpels and producing a single style. Each carpel ends in a bulging or 2-lobed stigma.
Diagram showing the stigma-style-ovary system of the female reproductive organ of a plant. The stigma is fixed to the apex of the style, a narrow upward extension of the ovary. The stigma (pl.: stigmas or stigmata) [1] is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower.
