Abstract


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.
