Obdiplostemony

As Obdiplostemonie in which is Botany a position of the flower organs referred to, wherein the further outwardly standing stamen circle parallel rather than gap to the inner circle of the perianth stands.

During the development of obdiplostemonic flowers, the two stamen circles are laid out normally, i.e. the first alternating to the inner flower envelope circle and the second alternating to the outer stamen circle and thus parallel to the inner flower envelope circle. Then the carpels are placed in the center of the flower parallel to the stamens of the second circle and push them outwards during their development, so that at the end the stamen circle created as the second becomes the outer one and, due to the original position of its attachments, parallel to the inner bracts stands.
