摘要
Taraxacum pieninicum Pawl. (Asteraceae) 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 achene pericarp. Pollen grains of this species were of medium size, echino-lophate and 3-zonocolporate. The external surface of the achene body was of scale sculpture, covered with the spikes. Pappus hairs were not branched, built of a few tubular cells, with acute, protruding ends.
