Rhamnus davurica Pall.

Modern name

Rhamnus davurica Pall.

A deciduous shrub or small tree, ultimately 30 ft high; young branchlets glabrous; lateral twigs sometimes thorn-tipped. Leaves alternate or often nearly opposite, oblong or oval, tapering at the base, slender-pointed, finely toothed, 112 to 4 in. long, 34 to 112 in. wide, glabrous or somewhat downy beneath; veins in four to six pairs, converging towards the apex; stalk slender, 14 to 1 in. long. Flowers produced from the lower joints of the young shoots in June, forming dense clusters. Fruits black, about 14 in. in diameter.

Native of W. Siberia, the Russian Far East, N. China, and Mongolia, and with a variety in Japan (not treated here). It is very closely allied to R. carthartica and does not differ from that species in flower or fruit, but its leaves are longer, uniformly wedge-shaped at the base and with one or two more pairs of veins. Of little garden value except in rough shrubberies.
