Stamen, a microsporophyll in a fl., usu. a stalked organ, or filament, 

 bearing an anther, the latter composed of 2 lobes or ihecae, united by 

 a prolongation of the filament, the connective, each lobe with two 

 pollen sacs, opening by a definite line of dehiscence, or pore, to allow 

 escape of pollen. 



The androeceum or stamens may be hypo-, peri- or epi-gynoiis; 

 epi-phyllous- , -petalous, or -sepalous (concrescent with P, C, or K); 

 diplostenionous (in two whorls, the outer alt. with the C, and as 

 numerous), obdiplostemonous (in two whorls, the outer opp. or anteposed 

 to the pets., Caryophyllaceae), haplo- or iso-stenionous (in one whorl, 

 alt. or anteposed to C, as in Primulaceae), or in 2 whorls (Rosaceae). 

 The sta. may be few and definite (usu. under 20, often described as 

 won-, di-androus, &c., according to the number), or indefinite (over 20, 

 Ranunculaceae, Rosaceae, &c.); they may be all free (monandroits... 

 polyandrons), or concrescent in i, 2, 3, many bundles (mon-, di-, tri- 

 poly-adelphous] with free anthers, or including the anthers into one 

 mass (synaiidriutn, adj. synandrons) as in many Araceae, Cucurbi- 

 taceae, Cyclanthera, Phyllanthus sp. ; they may be concrescent also 

 with the gynaecium (gynandrotis, Orchidaceae), or have the anthers 

 only united [syngenesious, Compositae). There may be two sta. longer 

 than the rest (didynamous, Labiatae), or 4 (tetradynamous, Cruciferae). 

 The anther may be sessile or on a filament; may be joined to the 

 filament by its whole length (adna/e, dorsifixed, A in fig.) or by its 

 base (innate, basijixed), or balanced on it, forming a T (versatilf, C);
