If the hypanthium is present up to the base of the style(s), the flower is epigynous. 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 ...
Flowers with inferior ovaries are termed epigynous. Some examples of flowers with an inferior ovary are orchids (inferior capsule), Fuchsia (inferior berry), banana (inferior berry), Asteraceae (inferior achene-like fruit, called a cypsela ) and the pepo of the squash, melon and gourd family, Cucurbitaceae .
Flowers are highly specialized in relation to their pollinators. Flowers are hermaphrodite (rarely unisexual), generally zygomorphic (bilaterally symmetrical), usually resupinates (i.e., the floral parts rotate 180° during development), often conspicuous and epigynous (i.e., the perianth parts are arranged above the ovary).
In epigynous berries, the berry includes tissue derived from parts of the flower other than the ovary. The floral tube, formed from the basal part of the sepals, petals, and stamens, can become fleshy at maturity and is united with the ovary to form the fruit.
The flowers are pendulous, with a white, sometimes pink-tinged, [3] bell-shaped corolla with five teeth at the tip 8–10 mm (0.31–0.39 in) long, and above it a white calyx. They are borne in leaf axils , usually one to three per stem.
Flowers are generally large and showy, following the general monocot pattern, with inflorescences in thyrse-like spikes, zygomorphic to asymmetric, with two trimerous whorls of tepals. Gynoecium tricarpellate, ovary epigynous (inferior), two trimerous androecial whorls with stamens 6, 5 or 1. Stamens have elongated sterile filaments to which ...
Individual florets usually flower for 3–4 days. Commercial varieties are largely self-pollinated. Flowers are commonly yellow, orange and red, but white and cream coloured forms exist. [2] The dicarpelled, epigynous ovary forms the ovule. The safflower plant then produces achenes. Each flower head commonly contains 15–50 seeds; however, the ...
