In the Netherlands two morphologically distinct groups of plants occur in the section Pilosellina of the genus Hieracium. The diploids and (very rarely occurring) triploids are restricted (as far as is known up till now) to the Isle of Terschelling and belong to the species Hieracium peleterianum Merat, whereas the tetra- and pentaploids belong to the species H. pilosella. This is the first record of Hieracium peleterianum for the Netherlands.
