A genus of a single deciduous species with alternate leaves and small flowers crowded in terminal, globose heads, subtended by several bracts. The flowers have no petals, but numerous stamens, which furnish their chief attraction. The nearest allied genera are Parrotiopsis (q.v. for the marks of distinction), Sycopsis, which is evergreen, and Fothergilla, which has no bracts beneath the head of flowers. The genus is named after the German F. W. Parrot, who made the first ascent of Mt Ararat in 1829.
