[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 ...
Valvular – anthers opening through valves or small flaps; e.g. Berberis. Versatile – anthers pivoting freely on the filament. Pollen – Stamen – Anther – the distal end of the stamen where pollen is produced, normally composed of two parts called anther-sacs and pollen-sacs . Filament – the stalk of a stamen.
[2] 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.
Diagram of an anther in cross section. 1: Filament; 2: Theca; 3: Connective (the conducting vessels in red); 4: Pollen sac (also called sporangium) The androecium is one of the fertile cycles of flowers. The parts that make up the androecium are called stamens whose function is the generation of male gametophytes or pollen grains.
Corolla: Cup-shaped, petals six, 50 mm (2 in) long, in two rows, imbricate, hypogynous, greenish yellow, marked toward the base with yellow. Somewhat fleshy in texture. Stamens: Indefinite, imbricate in many ranks on the base of the receptacle; filaments thread-like, short; anthers extrorse, long, two-celled, adnate; cells opening longitudinally.

The peduncles are jointed near the apex and persist after the flower falls off; the flowers are usually conspicuous, with ruffled petals and numerous stamens that are reflexed in the bud, usually having porous anthers. The fruits are small follicles containing seeds with aril, the calyx is persistent, sometimes acrescent, and the filaments are ...
The scales are obovate, lobed, and fringed, membranous, hairy or smooth, and usually caducous. The male flowers are without calyx or corolla, and comprise a group of four to 60 stamens inserted on a disk; filaments are short and pale yellow; anthers are oblong, purple or red, introrse, and two-celled; the cells open longitudinally. The female ...
