Dutch material of Ornithogalum umbellalum L. sensu lato was cytologically investigated. Two cytotypes appeared to occur, with the chromosome numbers 2n = 27 and 2n = 54. A description of the triploid and hexaploid plants is given. The triploids should be assigned to O. umbellatum, the hexaploids may be assigned provisionally to O. divergens Bor. The taxonomic status of the latter species is discussed. Further research is required for the solution of the taxonomic problems.
