Then the resultant structure is called perianth whose individual units are called tepals.A. Thalamus is the swollen end of the peduncle that bears flowers.B. Pedicel connects individual flower to the inflorescence.C. The perianth is the non-essential floral whorl without differentiation of calyx and corolla.D.
