ANGIOSPERM HALLMARK. “Fertilization of both egg and central cell is a major distinguishing feature of flowering plants. Almost 120 years ago, Sergei Gavrilovich Navashin (1898) and Léon Guignard (1899) described independently for the first time that two fertilization events occur in lily, a major model plant at that time. The universality of this observation was confirmed in numerous flowering plant species (angiosperms) and is now widely considered as a major feature distinguishing angiosperms from all other organisms.”
