Rhamnus davurica is a species of flowering plant in the buckthorn family known by the common name Dahurian buckthorn. [1] [2] It is native to China, Korea, Mongolia, eastern Siberia, and Japan. It is present in North America as an introduced species. [3]
This plant is similar to common buckthorn, but the stems are more stout and the leaves are longer. In its native range it may be up to 10 meters tall. It may also reach up to 9 meters in cultivation. The oppositely arranged leaves are up to 13 centimeters long by 6 wide in its native range, and usually smaller where it is introduced. The male flowers are just under a centimeter long and the female flowers are slightly smaller. The fruit is a drupe containing two seeds. [3]
In the United States this is an invasive species, growing in woodlands, forests, and other habitat types. In its native China it occurs in wet places, such as the edges of canals. [3]
Rhamnus is a genus of about 110 accepted species of shrubs or small trees, commonly known as buckthorns, in the family Rhamnaceae. Its species range from 1 to 10 meters (3'-30') tall and are native mainly in east Asia and North America, but found throughout the temperate and subtropical Northern Hemisphere, and also more locally in the subtropical Southern Hemisphere in parts of Africa and South America. One species, the common buckthorn, was able to flourish as an invasive plant in parts of Canada and the U.S.

It is a perennial herb producing an erect stem from a thick taproot, usually measuring 40 to 80 centimeters tall, but known to well exceed one meter. The leaves are up to 30 centimeters long and are generally lance-shaped with curled edges. The inflorescence is an interrupted series of clusters of flowers with 20 to 25 in each cluster, each flower hanging from a pedicel.

It is hairy, the upper hairs glandular, making the plant sticky in texture. The lower leaves are widely lance-shaped, up to 8 centimeters long by 1.5 wide. Upper leaves are smaller. Flowers occur in a terminal cyme at the top of the stem, as well as in some of the leaf axils, where they nod or hang like a bell. Each has a hairy, glandular calyx of fused sepals with ten veins. The calyx is open at the tip, revealing five white, pinkish, or greenish petals each with two rectangular lobes at the tip. The very long stamens and three styles protrude from the flower's center.
