Important part of the flower. Formed by the filament and anther. Filaments slender, anthers at the top of filaments, enlargement into cystic, endogenous pollen. All of the stamen flower called the stamen group total. Stamen stamen base because of the number and shape of plant species to another.

Stamen (stamen) Seed plants produce pollen organs. By the filament and anther two parts. Square or above the flower of the receptacle arranged in round or spiral. Due to the number of different plant species, in general, the number of the original variety and not necessarily of high and tends to reduce the number of kinds of a certain amount. A generic term for flower stamen stamens all groups. Stalk-like part of the base of the filaments of stamens, anthers and stretching from the support role. Generally elongated, such as silk, but also as a flat band (such as lotus), or completely disappear (e.g., gardenia), or transformed into a petal (e.g., canna). Filament length, free or connate, because plant species to another. Filigree flower is usually the same length. But there are also the same flower filaments of varying lengths. For example, cruciferous plants flowers, six stamens in two rounds, filaments shorter outer two stamens, the longer four wheels, called tetradynamous; Labiatae plants and flowers Scrophulariaceae , 4 stamen filaments two long and two short, saying didynamous. Filaments usually separated from each other, but there are some or even all together, such as cotton, synthetic filaments even bunch, tubular shape, said monomer stamens; beans, locust synthetic filaments two beams, said diadelphous; ricin Even synthetic multi-beam filaments, called multibody stamens. Anther filaments dilated cystic top part was. Often separated into two drug medicine room, and each room has a drug or two pollen sacs. Anther local produce pollen. Anther wall is formed by the skin layer, the fiber layer, the intermediate layer and the tapetum. Tapetum special cell layer surrounding the pollen sac, with a dual-core or multi-core structure, cells containing more rna and proteins, and fats and carotenoids and other nutrients, with a supply of nutrients required for pollen development role. When mature pollen, pollen sac itself cracking, shed pollen. Anther filaments according to the students on the way, can be divided into full-forward medicine (all the students in the anther filaments, such as lotus), at the end of the drug (anther filaments top of its base was born, such as sedges, flat fruit grass etc.), carrying medicine (with its back against the anther filaments, such as verbena, dogwood, etc.), versatile drug (anther recumbent, with its back that was born in the middle of the top of filaments, such as lilies, rice, etc. ) and other types. Compositae stamen filaments separated anther joint, called poly drug stamens.

Filaments
Stalk-like part of the core base of support, and stretch from anther role. Generally elongated, such as silk, but also as a flat band (such as lotus), or completely disappear (e.g., gardenia), or transformed into a petal (e.g., canna). Filament length, free or connate, because plant species to another. Filigree flower is usually the same length. But there are also the same flower filaments of varying lengths.

Anther
Filaments dilated cystic top part was. Often separated into two drug medicine room, and each room has a drug or two pollen sacs. Anther local produce pollen. Anthers from the periphery of the cell wall anticlinal and periclinal division to form the drug chamber wall (the development of fibrous layer) middle (degenerated) and tapetum (degenerated) line to pass. Tapetum special cell layer surrounding the pollen sac, with a dual-core or multi-core structure, cells containing more RNA and proteins, and fats and carotenoids and other nutrients, with a supply of nutrients required for pollen development role. When mature pollen, pollen sac itself cracking, shed pollen. Anther filaments according to the students on the way, can be divided into full-forward medicine (all the students in the anther filaments, such as lotus), at the end of the drug (anther filaments top of its base was born, such as sedges, flat fruit grass etc.), carrying medicine (with its back against the anther filaments, such as verbena, dogwood, etc.), versatile drug (anther recumbent, with its back that was born in the middle of the top of filaments, such as lilies, rice, etc. ) and other types. Compositae stamen filaments separated anther joint, called poly drug stamens.

Type
Stamens often due to different clutch or not, filament length, divided into different types, common are: 1 distinct stamens (stamen distinct) a majority of the flowers have stamens and separated from each other, such as lotus, wheat flower stamens. 2 single stamen (monadelphous stamen) in a 10 to spend most of stamens, whose filaments even synthetic bouquet, consisting of filament tube, anther separation, such as cotton, kenaf, mallow, Crotalaria flower, lupine, etc. flower stamens. 3 two-body stamens (diadelphous stamens) in 10 stamens of a flower even synthetic filaments two beams, such as beans, peas stamens, where nine filaments even synthetic bunch, the other a single stamen separation, or 5 per bundle . This stamens of Fabaceae (or Leguminosae) plant-specific. 4 multibody stamens (polydelphous stamens) a majority of the flower stamen filaments even number of beam synthesis, such as hypericin and generations flower stamens. 5 tetradynamous (tetradynamous stamen) flowers have six stamens, two short outer filaments, and four long filaments within the wheel, such as rape, radish flower stamens. Such stamens of cruciferous plants endemic. 6 didynamous (didynamous stamen) a flower has four stamens, two long, two short, such as paulownia, Glechomae, motherwort flower stamens. 7 poly drug stamens (synantherous stamen) a flower stamen filaments separated synthetic tubular anthers stickers, such as sunflower and pumpkin Compositae, etc. Gloxinia flower stamens.
