  In studying the karyotypes of different varieties of Hyacinthus orientalis which have chromosomes with permanent secondary constrictions, del Mol (1927) found correlation between the number of chromosomes with constrictions and the number of nucleoli.

  I have proposed myself, independently from Delaunay, the same term ‘Karyotype’, but merely for designation of nuclear peculiarities of a given organism or systematical unit.
