The work presents the results from the studies on the morphological and anatomical differentiation of Primula veris seeds from the natural localities and from the cultivation. On the basis of the biometrical analysis the very little inter-population variability and no distinct seasonal variability was stated. The increase of the seed’s size, the endosperm’s thickness and the embryo’s breadth in seeds from the cultivated plants was observed.
Occurrence requirements and spatial organisation of cowslip (Primula veris L.) natural populations from the Wielkopolska region were examined. On three chosen localities of P. veris the permanent plots were established in 1996 and 1997. The chemical analyses of the soil samples were made and the participation of different species in the examined populations was determined. On the basis of cartographic documentation and the value of the dispersion coefficient, the type of the spatial structure was determined.
The cowslip plants (Primula veris L.) in three natural populations in Wielkopolska flowered on 37.03% to 75.00% of individuals. In all the examined populations most of the cowslip plants had only one generative shoot. The mutual proportion of individuals with pin and thrum flowers was different. The fructifying intensity was rather low, and the real seed production (RSP) varied from 35.80 to 43.81 seeds in one capsule.
Primulic acid, reparil and lignocaine were comparative analysed in consideration of acute toxicity, influence on circulation and local anaesthetic activity. High cell membrane activity of primulic acid has been shown.

Poddano farmakologicznej analizie porównawczej kwas prymulowy, reparil i lignokainę w zakresie toksyczności ostrej, działania krążeniowego oraz aktywności miejscowo znieczulającej, wykazując wysoką aktywność błonową kwasu prymulowego.
The cowslip plants (Primula veris L.) in two natural populations in Wielkopolska set fruits in 80% on plants with one generative shoot. Mean number of fruits by a rosette varied from 4.7–9.0. In both populations the mean number of fruits by a scape and the value of a real seed production by a single capsule was higher for rosettes with one scape than for plants with two generative shoots.
