Two-year-old cones were collected from 388 dwarf mountain pine (Pinus mugo Turra) plants of ten populations of this species from the Tatra Mts. - five of them from calcareous and five from calcium-free undersoil. Their 14 morphological traits are described. The data served for performing multivariate analysis of variance and testing of statistical hypotheses, for discriminate analysis. for calculating Mahalanobis distances between populations and plotting a dendrite based on the shortest Mahalanobis distances and for agglomerative clustering by the method of nearest neighbourhood. Wide differences in the populations were found as regards all the studied traits and the existence of two groups in the population, which, do not, however, correlate with the substrate type. The "calcareous and calcium-free" populations show statistically significant differences in six of the 14 studied traits
