This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in Magnolia, or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in Lilium).

Ligulate floret, typical for some members of the family Asteraceae: A. inferior ovary B. The calyx is a crown-shaped pappus, called a corona. C. Anthers are united in a tube around the style, though the filaments are separate. D. A ligulate petal extends from the tubular corolla. E. style and stigmas

In some taxa, for instance some magnolias and water lilies, the perianth is arranged in a spiral on nodes, rather than whorls.
