Unusual gender types in some Pistacia species are considered as useful material for pistachio breeding. In this report, the inflorescence characteristics of an exceptional monoecious Pistacia atlantica Desf. tree population were presented. The gender distribution was highly complex and variable among the trees. Some of the branches bore only female or male inflorescences. Also, some branches bore inflorescences belonging to both sexes concurrently. Besides, there were several branches having mixed clusters comprised the flowers of both sexes separately or hermaphrodite flowers in which the pistil and stamen concurrently appeared in some trees. In hermaphrodite flowers, defected floral organs were abundant.
