Quercus dentata / Kashiwa カシワ

Quercus dentata: A deciduous tree that inhabits poor or gravelly soil in fields and mountains and grows as tall as 15m and 60cm across. Leaves are alternate; blades measure 7-12cm long, 3-5cm wide, obovate-like long oblong, and leathery, with sharply pointed tips, broadly cuneate bases, big-sized serrations on half above, and glossy surfaces. Dioecious: Lower parts of new branches hang 5-10cm long male inflorescences with dense vellus hairs on the axis. Female inflorescences erect themselves at the sides of the upper part's new branches with 3-5 female flowers. Nuts are 1.5-2cm long, oosphere-shaped, and mature in the current year's autumn. Bloom time: April-May.
