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 ...
The stamens are highly modified leaves formed by a foot that is inserted into the receptacle of the flower, called filament, and a distal portion called anther. The filament is the sterile part of the stamen, it can be very long, short or missing, in which case the anthers are called sessile.
Any part of a microsporophyll that bears microsporangia is called an anther. Most anthers are formed on the apex of a filament. An anther and its filament together form a typical (or filantherous) stamen, part of the male floral organ. The typical anther is bilocular, i.e. it consists of two thecae.
A bundle or structure of stamens forming one unit in an adelphous flower; for example, the stamen tube around the pistil of Hibiscus. adelphous Having organs, particularly filament s such as stamen s, connected into one or more adelphiae, whether in the form of bunches or tubes, such as is commonly seen in families such as Malvaceae. Usage of ...
Stamens consist typically of an anther, made up of four pollen sacs arranged in two thecae, connected to a filament, or stalk. [2] The anther contains microsporocytes which become pollen, the male gametophyte, after undergoing meiosis. Although they exhibit the widest variation among floral organs, the androecium is usually confined just to one ...
The androecium (literally, men's house) is a collective term for the male organs (stamens or microsporophylls). While sometimes leaflike (laminar), more commonly they consist of a long thread-like column, the filament, surmounted by a pollen bearing anther. The anther usually consists of two fused thecae. A theca is two microspoorangia.
Schematic cross section of an anther. 1: Filament 2: Theca 3: Connective 4: Pollen sac (also known as sporangium) In botany, the connective is the portion of sterile tissue of the anther between and interconnecting the two thecae, [1] [2] which forms a body with them and holds them together.
