Resumen de Validation of the Hybrid Flowering Cherry Prunus ×incam (Rosaceae)

Richard T. Olsen, Alan T. Whittemore

• The name Prunus ×incam Ingram ex R. Olsen & Whittemore is validated here. Introduced as a cultivated variety in 1947, Ingram's name Prunus ×incam has been in use as a nomen nudum in horticultural literature and the nursery trade for artificial crosses involving the parent taxa P. incisa Thunberg × P. campanulata Maximowicz. Prunus ×incam is an early flowering tree with two or three flowers in each persistent involucre, spreading sepals, and pink, deeply emarginate petals. Ingram's original introduction, the cultivated variety �Okamé,� is the most widely grown form.
