Description: Unisexual flowers of Pistacia lentiscus based on an unvouchered plant from the Gargano Peninsula, Italy. A flower represented by only one of the sexes is also called an imperfect flower. This species is dioecious, i.e., the male flowers (top) and the female flowers (bottom) came from different plants. The flowers are anemochorous, i.e., pollinated by the wind. Note that the perianth is absent. Determination by J. D. Mitchell.
