Calyx | plant anatomy | Britannica
The sepals (collectively called the calyx) most resemble leaves because of their generally green colour. From their base and along most of their length, sepals remain either separate (aposepalous, or polysepalous) or marginally fused (synsepalous), forming a tube with terminal lobes or teeth. The… Read More

After initiation, the margins of the sepals become confluent and intercalary growth produces the synsepalous calyx. The periphery of the flower, interior to the sepals, now rises to form a ring primordium composed of three common petal/androecial primordia.
