Diadelphous stamens Stamens united into two, often unequal, sets; e.g., those of many Fabaceae, which have nine stamens in one set and one stamen in the other. Androecium of a papilionoid legume. Drawing by B. Angell.
Didynamous stamens With two pairs of stamens of unequal length. Didynamous stamens and staminode of a Bignoniaceae. Photo by S. A. Mori.
Heteromorphic stamens Stamens of two distinct types; one type usually bears fertile pollen and the other type bears sterile or fodder pollen; e.g., (Lecythidaceae) and species of (Fabaceae). Heteromorphic (= heterantherous) stamens of a species of Swartzia. Photo by S. A. Mori.

Urticaceous stamens Stamens that spring forward to release pollen at anthesis; typical of the flowers of the Urticaceae and some related families. Clavate filaments and lateral anther dehiscence. Drawing by B. Angell.
Vestigial stamens An appendage, most likely derived directly from a staminode and indirectly from a stamen, that no longer has an anther or the anther is small and withered compared to the fertile anthers of normal stamens in the staminal ring or the fodder pollen-producing antherodes of staminodes. The androecium of a zygomorphic-flowered Lecythidaceae. Photo by C. A. Gracie.
Vestigial stamens external Referring to an inwardly, once coiled androecial hood that possesses vestigial stamens only on the outside (externally of the coil. This feature is only used to describe species with at single coil. Medial section of flower of Lecythis minor. Photo by C. Galdames (SCZ).
Vestigial stamens external Referring to an inwardly curved hood that possesses vestigial stamens only on the outside of the coil; e.g., in the Lecythidaceae. Medial section of flower of Lecythis minor. Photo by C. Galdames (SCZ).
Vestigial stamens internal Referring to an inwardly, once-coiled androecial hood that possesses vestigial stamens on the inside (internally) as well as on the outside of the coil (externally). Flowers of Eschweilera tetrapetala. Photo by N. P. Smith.
