Abstract
THE discovery of a tetraploid form of Primula farinosa on the Baltic island of Gotland during the summer of 1950 was somewhat unexpected, as hitherto this plant has seemed a well-defined diploid species (n = 9), at least in Central and Northern Europe. This tetraploid form revealed n = 18 at meiosis (Fig. 1), and the plant appeared morphologically distinct from the British Primula, with more elongated spatulate leaves (Fig. 4).
