Buxus microphylla var. insularis / Chousenhimetsuge チョウセンヒメツゲ

Buxus microphylla var. insularis, an evergreen shrub or small tree, 0.3-1m in height, prefers to grow in limestone areas in hilly districts. Leaves are opposite, each leathery and glossy, in the shape of an oval or broad oblong, 1-1.5cm in length. Inflorescences emerge from the branch tops' axils, in which many small yellow flowers bloom; female flowers come in the center, and males surround them. Bloom time: March-April.
