The in Southern Europe with circa 30 species native genus is on the one hand partly very attractive and interesting, but at the same time also difficult in flower morphology and in discrimination of the several species. All species have, except Serapias perez-chiscanoi, reddish flowers. The flower structure is not easy to understand at first view. The sepals are grown together and build a closed helmet. The petals sit closely on the inside to the helmet. They are almost round to drop-shaped at the base and show a filiform extension. The lip is divided into two parts. The anterior part, the epichil, looks out of the helmet. The posterior part, the hypochil, is inside of the helmet. The side lobes of the hypochil are turned upwards and sit also closely on the inside to the helmet. The whole flower is in addition surrounded in the area of the pedicel by a bract, which corresponds a remodeled leaf.
