Rhamnus imeretina Kirchn.

Modern name

Rhamnus imeretina Booth, Petz. & Kirchn.

A deciduous shrub up to 10 ft high, with very sturdy shoots sparsely downy when young. Leaves oblong or oval, rounded or slightly heart-shaped at the base, taper-pointed, finely toothed, 4 to 10 in. long, 2 to 4 in. wide, veins parallel in fifteen to twenty-nine pairs, upper surface dark green and soon glabrous, except in the sunken midrib and veins; lower surface downy, especially on the veins; stalk 12 to 34 in. long, downy. Flowers green, in small, axillary clusters. Fruits 25 in. long. Bot. Mag., t. 6721.

Native of the western Caucasus up to 8,500 ft, and of N.E. Anatolia; introduced to western Europe in the 1850s by the nurseryman James Booth of Flottbeck near Hamburg. He apparently listed it as R. imeretina in his catalogue but the name was first validated by Kirchner in Arboretum Muscaviense (1864), a descriptive catalogue of the trees and shrubs growing in the Muskau Arboretum, Germany. It was introduced to Britain in 1879 and at first confused with R. libanotica (see below).

R. imeretina is a very handsome, large-leaved, quite hardy shrub – the finest of all the buckthorns. The leaves may occasionally be as much as 14 in. long and 6 in. wide. The leaves die off a deep bronzy purple in the autumn.

R. libanotica Boiss. – This closely allied species is distinguished from

R. imeretina by its smaller leaves with only fifteen or fewer pairs of veins. Native of Lebanon, the Latakia area of Syria, and S. Anatolia.
