Antipetalous Stamen Position | Opposite the petals. |  |
Antisepalous Stamen Position | Opposite the sepals. |  |
Appendicular Stamen | Typical stamen with a variously-shaped or modified, protruding connective, as in Viola. |  |
Didymous Stamen Arrangement | With stamens in two equal pairs. |  |
Didynamous Stamen Arrangement | With stamens in two unequal pairs. | |
Filantherous or Typical Stamen | Stamen with distinct anther and filament with or without thecal appendages, as in Rhexia or Vaccinium. |  |
Laminar Stamen | Leaf-like stamen without a distinct anther and filament but with embedded or superficial microsporangia, as in Degeneria. |  |
Petalantherous Stamen | With a terminal anther and distinctly petaloid filament, as in Saxifraga. | |
Petaloid Stamen | Petal-like stamen without distinct anther and filament but with marginal microsporangia, as in Magnolia nitida. |  |
Stamen | The male sporophyll within the flower; the floral organ that bears pollen in angiosperms. |  |
Stamen Anther | Pollen-bearing portion of stamen. | |
Stamen Filament | Stamen stalk. | |
Stamen Structural Types | Classification based primarily on structure of filament and anther. In this classification intermediate types of stamens do occur; shapes, apices, and bases of anthers should be described separately and independently of stamen type. | |
Tetradynamous Stamen Arrangement | With stamens in two groups, usually four long and two short. |  |
Tridynamous Stamen Arrangement | With stamens in two equal groups of three. | |
