From Wikipedia, the free encyclopedia
The cultivar 'Berardii' was raised from seeds collected by Simon-Louis from large trees growing on the ramparts at Metz. It made a small tree or shrub, with minute, glabrous leaves 12 mm - 18 mm long, deeply incised by relatively few teeth. As with 'Koopmannii', 'Berardii' is treated in some east European treatises as a cultivar of the Siberian Elm Ulmus pumila. Green, who had examined dried specimens of the plant, also considered it "as possibly a form of U. pumila" [1]. A specimen was once grown at Kew Gardens, obtained from the Späth nursery before the First World War [2], but the tree is not known to remain in cultivation, although similar small-leaved trees have been recorded from the south Essex coast in England to eastern France.
