The inflorescence-axis bears a spathe and a single pendulous flower. The two whorls of the perianth are composed of separate perianth-leaves; the outer whorl differs in appearance from the inner whorl, so that we may speak definitely of three sepals and three petals. The stamens are not inserted on the perianth, they are epigynous. Each anther opens by two terminal pores. (See also page 32.) IRIDACE.^ (Crocus Family) Perennial herbs with rhizomes or corms. Flowers usually regular, cyclic, epigynous, conspicuous. Perianth 3 + 3, peta- loid. Stamens three, with extrorse anthers. Carpels three, syncarpous ; ovary three-chambered, with many ovules on axile placentae; stigmas three.
