ANGIOSPERM FUSIONS. “During the evolution of the angiosperm flower, the ovule-bearing carpels become enrolled and sealed with the ovules inside, with carpel fusion being a derived state for the angiosperm flower. Once the carpel is formed, syncarpy, or the congenital fusion of multiple carpels to form a multicarpellate ovary, dominates angiosperm evolution, with an estimated 80% of all angiosperms bearing syncarpous ovaries.”
