Corylus sieboldiana Betulaceae
They are a deciduous shrub that grows wild in the mountain area. The trunk grows to be about 10 cm wide. Cortex is tinged with pale gray-brown and smooth to touch. They have both rounded lenticel and horizontally long lenticel. The leaves are wide egged-shaped about 3 to 11 cm long with the sharp top as well as with a scraggly finely sawtooth (sawtooth: Kyoshi, serrated edges like a saw- serrated edges at the tip of a leaf). The blossom seasons are about March to May. As they are a monoecious plant, the flowers bloom earlier than the leaves shoot. Spikes of male flowers dangle from the branch that grew the previous year, and the color is yellowish red-brown, about 3 to 13 cm long. Female flowers sprout at the upper branch than male flowers and they blossom with some red flowers gather in cluster. When the flowers wither, female flowers change themselves into rolled shape to hold the seeds with dense aculeus growing entirely. The top is unique long shape extending like beak, about 3 to 5 cm long. In October the seeds get matured to be edible.
