The capsules dehisce (split open), laterally (similar to "Iris korolkowii"). Ripe capsules dehisce or are cracked open by birds. The sporangia will dehisce longitudinally, forming slits through which spores are dispersed. Anthers on the tassel dehisce and release pollen, which is dispersed by the wind (anemophilous). The vaginal cuff has a tendency to partially or completely dehisce or open up. They dehisce along each edge to release up to 26 to 30 seeds each. They open (dehisce) along the top forming two equally sized valves. They have short beak, taper to a pointed apex and dehisce (split open) laterally. They dehisce (split open) below the apex of the capsule, with 3 lateral slits.
