Characteristics
Mature fruits are very helpful for identification but rarely are collected. The flowers are very showy and, in most of our irises, the sepals are the most prominent and largest part of the flower. The sepals are the brightly colored (violet, blue, copper, yellow) outer whorl that often have markings (e.g. yelllow or white) near the base and center. The petaloid stigmas (inner whorl) arch directly over the sepals and can be bifurcate at the tip. The petals are the middle whorl that alternate with the sepals, and in I. tridentata are rather small. However, in Iris domestica the stigmas are not petal-like.
