The number of stamens in each flower is a highly variable character. Some species of the euphorbiaceae family have flowers with only one stamen (they are called monanders), the oleaceae have two stamens (flowers dianders) and in the myrtaceae there are numerous (they are polyanders). The number of stamens may or may not be equal to the number ...
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 ...
In the 19th century, two contrasting methods of describing the flower were introduced: the textual floral formulae and pictorial floral diagrams. [2] Floral diagrams are credited to A. W. Eichler, whose extensive work Blüthendiagramme [3] [4] (1875, 1878) remains a valuable source of information on floral morphology.
"The cowslip (Primula veris) has two kinds of flowers in nearly equal proportions: in the one the stamens are long and the style short, and in the other the reverse, so that in one the stamens are visible at the mouth of the tube of the flower, in the other the stigma occupies the same place, while the stamens are halfway down the tube. The ...
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 .
In some flowers, a tube or cup-like hypanthium (floral tube) is formed above or around the ovary and bears the sepals, petals, and stamens. There may also be a nectary producing nectar. Nectaries may develop on or in the perianth, receptacle, androecium (stamens), or gynoecium. In some flowers nectar may be produced on nectariferous disks.
A flower's anatomy, as defined by the presence of a series of organs (sepals, petals, stamens and carpels) positioned according to a given pattern, facilitate sexual reproduction in flowering plants. The flower arises from the activity of three classes of genes, which regulate floral development: [8]
The flower is tubular, sometimes narrowing at the top, and varies in color; various shades of red, white, and yellow appear in different species. A hairy belt of varying width appears above the stamens. The tube of the flower varies in length from 9 to 60 mm across the genus.
