Opis:: A morphometric study of the three species of Lepidium L. sect. Dileptium DC. is presented. Multivariate methods (cluster analysis and canonical discriminant analysis) were employed to investigate phenetic relations between examined individuals. As a result a set of quantitative characters useful in species determination was proposed and discussed.

Opis:: Erysimum pieninicum (Zapał.) Pawł. (Brassicaceae) is an endemic species, growing only in Pieniny Mts. The aim of the presented work was to investigate its pollen morphology as well as its ultrastructural traits of pericarp and seed-coat. Pollen grains of this species were of small size, 3-zonocolpate with reticulate ornamentation. The external siliqua surface was of rugose sculpture, covered by numerous, stellate hairs. The internal surface of the fruit was naked and characterized by striate sculpture. The seed-coat ornamentation of E. pieninicum was of blister type.

Opis:: Cochlearia polonica Fröhl. (Brassicaceae) is one of the rarest species in the Polish and European flora and a taxon endemic to a very small area in southern Poland. Due to industrial activities and subsequent transformation of habitats it was extinct in all natural localities around 1994. The persistence of the species was ensured thanks to the active protection efforts including a series of transplantations based on the material from the last and decreasing natural population. The history of conservation efforts of C. polonica provides a model example of successful active protection in the European flora. Here, we provide a complete review comprising the following aims: (i) outline of the discovery and taxonomic conceptions on C. polonica, (ii) review of conservation efforts aimed at preserving its populations, (iii) description of the existing population resources, and (iv) analysis of the genetic structure of all existing populations based on previously published data and new, supplementary results.
