632 Ulmus minor Mill.

Syn.: int. al. U. carpinifolia Gled.

This species occurs in Europe and adjacent areas towards the south and southeast. In some parts of the range, it may be difficult to decide whether a population is native or cultivated. Thus, the maps of this tree (as of many other ornamental trees) vary in several respects. Cf. also Meusel et al. 1965, map p. 123.
