Oncocyclus is a section within the Subgenus Iris. Oncocyclus, Greek onco, swollen; with a circular swelling; refers to the fleshy aril on the seeds of these plants. The flowers offer no nectar reward. A number of species of medium-sized bees provide pollination services. Pollinators of Iris atropurpurea are night-sheltering male solitary bees, honey-bees and female solitary bees. Apis mellifera, the Western honey bee, is the most frequent diurnal visitor to Iris atropurpurea.
