The anthers are dorsifixed and pollen dehiscence occurs by longitudinal openings. Rare complications include lymphatic injury and major wound dehiscence. This can occur as a result of senescence, dehiscence or disinsertion of the levator aponeurosis. The androecium has two stamens and three staminodes, anther dehiscence is explosive. The sporangia open by lateral dehiscence to release the spores. Explosive dehiscence of sporangia is a characteristic of "Sphagnum". The stomium is the region of the anther where dehiscence occurs. Following dehiscence, the bud scar disappears. Unless wound dehiscence aesthetically compromises the breast-lift outcome, it is managed conservatively. Abdominal bandages are sometimes used to help prevent the risk of dehiscence. The ripe seed capsules undergo explosive dehiscence. The pollen grains are bicellular at the moment of dehiscence, usually open and angular. Flower buds of "Eucalyptus" and related genera open with circumscissile dehiscence. Once seed capsules have matured, seeds are dispelled around the plant through explosive dehiscence. Eusporangiate ferns do not generally have specialized dehiscence mechanisms.
