Monochlamydeons (from the Greek monos, one, chlamys, a cloak), is a term applied to flowers in which the perianth is represented by a single whorl of floral leaves. This whorl is generally green, or sepaloid, as in the nettles; but sometimes petaloid, as in mezereon. Such flowers occur mostly among the Incompleta; (q.v.); but not exclusively, many Ranunculaoeae, such as Clematis, Anemone, and Caltha, being monochlamydeons, though belonging to a dichlamydeous (q.v.) group.
