It is a small deciduous tree reaching a height of 8–20 m. The trunk is slender with smooth grey to purple-grey bark marked with horizontal brown lenticels, with a strong smell when cut. The leaves are elliptical to ovoid, 4–10 cm long and 1.8–4.5 cm broad, with a serrated margin with aristate tips to the serrations. The lowest teeth of a leaf feature two glands. The flowers are produced on 5–8 cm long racemes, each flower 7–10 mm diameter, with five white petals; they are hermaphroditic, and appear in mid-spring after the leaves. The fruit is a small drupe, about 8 mm in diameter, green at first, then red and finally ripening black in mid summer.Botanic Japan: Prunus grayana (in Japanese; google translation.Huxley, A., ed.
