Broussonetia papyrifera, a deciduous tree, has long
been cultivated for its materials in traditional Japanese paper and
grows wild in fields and mountains, characterized by its gray-brown
bark and yellow-brown lenticels. Current branches have dense,
velvety hairs. Leaves are opposite; blades measure 10-20cm long,
7-14cm wide, ovate, right-side and left-side irregular, varying from
no cuts to 3-5 deep cuts, with obtuse serrations on margins.
Surfaces have sparse, short hairs, and backsides have dense, velvety
hairs. Flowers are dioecious; male inflorescences and female ones
occur from the new branch's axils. Fruit (multiple) is spherical,
2-3cm in diameter, and matures orange-red in July-August. Bloom
time: May-June. |
