perianth defined in 1951 yearperianth - perianth;
perianth - Outer part of flower enclosing stamens and carpels, usually consisting of two whorls. In dicotyledons differentiated as an outer green calyx consisting of a whorl of sepals, and an inner, usually conspicuous, often coloured corolla consisting of a whorl of petals, e.g. buttercup. In monocotyledons there is usually no differentiation of calyx and corolla, both whorls being alike. In some flowers perianth is reduced, e.g. in stinging nettle where only calyx is present, and grasses where perianth is represented by two tiny scales (lodicules); or it is absent altogether, e.g. willow.
