Opis:
The complex of Salix retusa includes S. retusa s.s., S serpyllifolia and S. kitaibeliana, small, prostrate willows occurring in the subalpine and alpine vegetation belts of the mountains of Central Europe: the Pyrenees, Alps, Apennines, Dynaric Alps, Carpathians and Rila. The systematic positions of these taxa are not fully resolved and are still disputed. The aim of the present study was to biometrically verify differences in leaf characteristics between these taxa. Material was collected from 47 populations, each represented by 25–52 individuals (33 on average). The study was based on 14 leaf morphological characters measured from scans using Win Folia software. The principal component analysis (PCA), Ward’s agglomeration method, the K-means cluster analysis (K-MCA) and Kruskal-Wallis tests were applied to verify the relationships between taxa and their populations. Differences between average leaf characteristics of S. retusa s.s., S. serpyllifolia and S. kitaibeliana were detected. The Pyrenean populations of S. retusa s.s. appeared more similar to S. serpyllifolia. Within the Alpine populations of S. serpyllifolia, several individuals resembling S. retusa s.s. were detected, and vice versa, within populations of S. retusa s.s., and there were also individuals similar to S. serpyllifolia. The controversial S. kitaibeliana was found to be typical of the Tatra Mountains. The results support close taxonomic relations, but also the separate status of S. retusa, S. serpyllifolia and S. kitaibeliana. The differences between them are mainly of a quantitative nature.

Opis:
The relict tree species Zelkova abelicea and Z. sicula (Ulmaceae) occur in Crete and Sicily, respec- tively. Zelkova abelicea grows in approximately 40 localities in the mountains of Crete, while Z. sicula has been found in only two stands in Sicily. We compared 25 morphological characters of the leaves of both species and used statistical methods (Tuk- ey’s test, discrimination analysis, principal component analysis, agglomeration) to reveal the differences between these two species, their relation to Z. carpinifolia (the third Zelkova south-west Eurasian species), and between the leaves from different shoot types. Our study represents the first comparative biometric analysis of the three Zelkova species localized in the western edge of the current geographic range of the genus. We found that the species differed from each other both, in terms of leaf form characters and level of leaf variation. Zelkova carpinifolia was clearly differ- ent from Z. abelicea, while the two populations of Z. sicula, SIB and SIA, were more similar to Z. carpinifolia and Z. abelicea, respectively. The latter finding supports the results of recent molecular studies suggesting the hybrid origin of Z. sicula. Zelkova abelicea, Z. sicula and Z. carpinifolia differ each other in the leaf characteristics and level of phenotypic variation.

Opis:
The putative hybrid character of two Tilia varieties selected as avenue trees (‘Szent Istvan’ and‘K3’) should be clarified for further breeding activities. Their ancestor species should be identified by a genetic comparison with reference material (Tilia cordata, T. platyphyllos, T. dasystyla, T. × euchlora, T. × europaea and others). RAPD marker data were evaluated by UPGMA cluster and neighbour-joining analysis. The genetic comparison of the two selected clones with the collection of reference material offers insights into some systematic relationships within the genus Tilia. It was supplemented by a critical discussion of methods of RAPD data evaluation for taxonomic purposes.
