The enlarged showy calyx-lobes in Mussaenda are good examples. The calyx-lobes, so called calycophylls, are mostly leaf-shaped, but have bright color, papillate epidermis, and loose mesophylls, features generally only found in petals. In higher eudicots, floral organs are typically arranged in four different whorls, namely sepals, petals, stamens and carpels.
