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.
The inflorescence, which rises above the surface of the water, is a raceme made up of several whorls of flowers, the lowest node bearing female flowers and upper ones bearing males. The flower is up to 2.5 centimetres (1 inch) wide with white petals. The male flowers have rings of yellow stamens at the centers.
Stamen is the Latin word meaning "thread" (originally thread of the warp, in weaving). [8]Filament derives from classical Latin filum, meaning "thread" [8]; Anther derives from French anthère, [9] from classical Latin anthera, meaning "medicine extracted from the flower" [10] [11] in turn from Ancient Greek ἀνθηρά (anthērá), [9] [11] feminine of ἀνθηρός (anthērós) meaning ...
A cyclic flower is a flower type formed out of a series of whorls; [1] sets of identical organs attached around the axis at the same point. Most flowers consist of a single whorl of sepals termed a calyx; a single whorl of petals termed a corolla; one or more whorls of stamens (together termed the androecium); and a single whorl of carpels termed the gynoecium.
From centre outwards: Trilocular ovary, 6 stamens, 6 tepals. Ornithogalum umbellatum, the garden star-of-Bethlehem, grass lily, nap-at-noon, or eleven-o'clock lady, a species of the genus Ornithogalum, is a perennial bulbous flowering plant in the asparagus family (Asparagaceae).
Heterostyly is a unique form of polymorphism and herkogamy in flowers. In a heterostylous species, two or three morphological types of flowers, termed "morphs", exist in the population. On each individual plant, all flowers share the same morph. The flower morphs differ in the lengths of the pistil and stamens, and
The plant usually forms a stout groundcover, but its flowers may reach up to 25 cm (10 in). Flowers are solitary and brightly colored with many narrow petals. The flowers open in bright sunlight, and are up to 30 millimetres (1.2 in) in diameter. Stamens are maroon with purple or yellow anthers, and are found in the center of the flower in rows ...
The terminal flowers are solitary in many species. In others the terminal inflorescence is cymose or racemose. The flowers are odourless and regular. There are many stamens, mostly 16 to 60, arranged in two separate whorls, the outer one with stamens alternating with petals, the inner one opposite, or numerous in the subfamily Papaveroideae.
