Rhamnus alnifolia is a species of flowering plant in the buckthorn family known by the common names alderleaf buckthorn,[1] or alder buckthorn. Unlike other "buckthorns", this alder buckthorn does not have thorns.[2] It is native to North America, where it is known mainly from the southern half of Canada and the northern half of the United States and California.[3][4] It can be found in forested habitat.
Description

Rhamnus alnifolia is a spreading shrub usually 50 to 150 cm (20 to 59 in) tall,[5] rarely to 2 m (6 ft 7 in), its thin branches bearing deciduous leaves.[6] The thin, deeply veined leaves have oval blades 4.5 to 11 cm (1+3⁄4 to 4+3⁄8 in) long, pointed at the tip and lightly toothed along the edges.[5] The inflorescence is a solitary flower or umbel of up to three flowers occurring in leaf axils. The tiny flowers are about 1 mm (0.04 in) wide[6] and have five green sepals but no petals.[7] Female flowers produce drupes 6 to 8 mm (0.24 to 0.31 in) wide, each containing three seeds. The drupes darken to black when ripe.[5]
