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 .
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.

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).
Cassia is a genus of flowering plants in the legume family, Fabaceae, and the subfamily Caesalpinioideae.Species are known commonly as cassias.The genus includes 37 species and has a pantropical distribution. [2]
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.
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 .
