The Chinese cornel ( Cornus chinensis Wangerin ) is a shrub or small tree belonging to the dogwood genus . It looks similar to the European cornel ( Cornus mas ), but comes from southern China. The Chinese name is 川 鄂 山茱萸 (chuān è shān zhū yú). Sometimes Cornus kousa var. Chinensis is inaccurately referred to as C. chinensis .
description
This species is about four to eight meters high, often grows as a small tree with a single stem, with sufficient sunlight also multi-stemmed and with an extended crown. The bark on the trunk and thicker branches is dark brown.
The oval, full-margined leaves are about six to eleven centimeters long, as in many other dogwoods , the five to six side nerves next to the midrib are bent forward. The underside of the leaf is lighter in color, there are gray hairs in the armpits of the lateral nerves. The Chinese cornel is deciduous.
The flowers appear in spring, before the leaves shoot. They are combined into small lateral umbels , two of which are opposite each other on the branch, the terminal bud only leaves leaves. Each umbel is framed by four inconspicuous bracts . The petals are yellow. The flowers develop elongated, about one centimeter in size, dark red to black drupes by autumn . The fruits are eaten by numerous birds and mammals, which thus ensure the spread ( zoochory ).
The number of chromosomes is 2n = 18.
