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 anther is the fertile part of the stamen and usually consists of two distinguishable, contiguous parts, called thecae, joined by an area called the connective, which is also where the anther joins the filament. It is usually formed by two thecae, sometimes it can be constituted by a single theca as in malvaceae and cannaceae or by three in ...
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. Each theca contains two microsporangia, also known as pollen sacs.
To distinguish the two species, the only reliable characters are the lengths of the filaments and anthers. In absolute terms, the filaments and anthers of T. scouleri are almost always longer than the corresponding characters in T. ovatum. The minimum, average, and maximum lengths of the filaments and anthers of each species is as follows: [3]
In such cases, examine the stamens. The anthers of T. cernuum are slender, lavender-pink or purplish, with the anthers and filaments approximately equal in length, while the anthers of T. flexipes are thick, creamy white or yellow, with the anthers greatly exceeding the length of the usually very short filaments.

The male stamen is inside the tube-shaped corolla of the disk floret. It has five anthers, five filaments, and produces pollen. The anthers and filaments are readily visible as separate entities in non-Asteraceae species. Here, they are fused together to form a cylinder, or tube, with their pollen on the inside only.
Sebaceous filaments are responsible for directing oil flow from sebaceous glands to the surface of skin, and can get clogged with dead skin cells and excess oil, making them appear as small dots ...
The stamens consist of an awl- to thread-shaped filament and an anther. The filament closest to the branch tip is shorter and upright and carries a large yellow anther. The longer two filaments, facing away from the tip of the branch, are somewhat spreading and carry smaller reddish anthers.
