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 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.
A plant that loses all of its leaves only briefly before growing new ones, so that it is leafless for only a short time, e.g. approximately two weeks. bristle A straight, stiff hair (smooth or with minute teeth); the upper part of an awn (when the latter is bent and has a lower, stouter, and usually twisted part, called the column ).
Deep purple flowers, with veins; have a reddish, double basal spathe (a large sheathing bract enclosing the flower). Petals are narrow. The branches of the stigma are unusually short and do not rise above the throat of the flower and end below the bases of the anthers. The anthers are long, yellow, with reddish filaments. Corms produce 10 to 12 ...
Such organs are described as connate or adnate, respectively. When like organs that are usually well separated are placed next to each other, but not actually connected, they are described as connivent (that is the case for anthers in several genera, such as Solanum). The stamens of Hibiscus (like many Malvaceae) are synfilamentous.
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]

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.
