Abstract
Abstract. The chromosome numbers of nine species of shrubs and trees from the Bulgarian flora are reported: Acer negundo, Corothamnus procumbens, Cotoneaster nebrodensis, Fraxinus excelsior, F. oxycarpa, Lembotropis nigricans, Pyrus pyraster, Ulmus laevis, and Viburnum lantana. For seven species, the chromosome numbers are reported for the first time from Bulgarian populations. For the species F. oxycarpa, this is the first record of the chromosome number; for L. nigricans and V. lantana, the chromosome numbers reported here confirm the earlier reports of Bulgarian origin.
