Abstract: In this study chromosome numbers of several individuals of Honckenya peploides from Surtsey and other locations across the northern hemisphere were obtained. Metaphase chromosomes were extracted from meristem tissue in root tips, stained with a fluorochrome and counted from photos that were taken at 1000x magnification. Some plants from this study displayed the formerly recorded somatic chromosome number of 2n = 68, while many specimens appeared to have lower chromosome numbers. This would indicate the presence of lower ploidys within the species, which seems possible and likely for a pioneer plant, with great dispersal abilities and genetic variety, such as H. peploides.
