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 .
[2] [4] Dampiera altissima has epigynous flowers, with the ovary of each flower sitting below the petals. The plant has 1-2 ovules, which are upright. [5] The calyx lobes, each 1 to 2 mm (0.04 to 0.08 in) in length, are equally winged and have high density of hairs.
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 ...
Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces. [note 1]
The flowers produce seeds which, when germinated, take five to seven years to produce a flowering plant. (Sexual seed reproduction mixes the traits of both parent flowers, so if garden hybrid cultivars are planted close to wild populations of Narcissus pseudonarcissus , there is a danger that the new seedlings, having hybrid vigour , could out ...
Each leaf is 2.5 to 6.5 cm (1 to 3 in) wide and 8 to 20 cm (3 to 8 in) long. A plant typically bears a single flower but occasionally there will be an inflorescence of two flowers. The small flower has six white tepals , each approximately 2 cm (0.8 in) long, and six protruding white stamens with pollen-dusted anthers .
They are epigynous, with the ovary inferior (lying below the attachment of the other flower parts). [1] After three months, the flower heads develop into a fleshy globular multiple fruit (syncarp) joined by their calyces (each flower becoming a fruitlet containing one seed). They are around 4 to 5 cm (1.6 to 2.0 in) in diameter, about the size ...
