Ilex latifolia |
Ilex latifolia (tarajo holly or tarajo; Japanese: 多羅葉 (たらよう, tarayō), Chinese: 大叶冬青 dà yè dōngqīng) is a species of holly, native to southern Japan ( Shizuoka Prefecture south to Kyūshū) and eastern and southern China ( Jiangsu south to Fujian and west to Yunnan), growing in broadleaf forests at altitudes of 200–1,500 m. [1] [2] [3] [4]
It is a small to medium-sized evergreen tree growing to 10–20 m tall with a trunk up to 60 cm diameter. The bark is dark brown, with a rough surface. The leaves are alternate, broad lanceolate to ovate-oblong, 8–24 cm long and 4–8 cm broad (among the largest of any species of holly), glossy dark green above, paler below, with a thick, leathery texture and serrated (but not spiny) margins. The flowers are yellowish-green, with a four-lobed corolla, produced in late spring; it is dioecious, with male and female flowers on separate trees. The fruit is a drupe 7 mm diameter, ripening orange-red to dark red in winter, and containing four seeds; they are often produced in dense clusters on the stems. [2] [3] [5] [6] [7]
It is cultivated as an ornamental tree in parks and temple gardens. [3] The leaves may be infused to make tea ("bitter nail tea" kǔ dīng chá). [8]
