Alnus sieboldiana / Oobayashabushi オオヤシャブシ

Alnus sieboldiana, a small deciduous tree growing to 5-10m in height and 6-10cm in diameter, with gray-brown branches, inhabits hilly regions near seashores, growing well even in poor soils and invading into, for example, landslide scars. Leaves are of alternate phyllotaxis; blades are long ovate, 6-12cm long, 3-6cm wide, tips sharply pointed, bases circular, and left-right asymmetric, with sharp double serrations on margins. Flowers are monoecious and bloom almost simultaneously with the development of the leaves; male inflorescences, now petioles, 4-5cm long, somewhat stout, curve in a bow way, and droop down from axils on previous year's branches. Females, with 1-2cm long petioles, set themselves below the males. Bloom time: March-April.
