- Abstract
This study investigates the genetic differentiation within the Central European Armeria maritima (Mill.) Willd. complex with special reference to the metallicolous populations using AFLP markers. Our sampling comprised all metallicolous (ssp. halleri, hornburgensis, bottendorfensis, eifeliaca, calaminaria), and non-metallicolous taxa (ssp. maritima, elongata, alpina). Geographical and genetic distances between populations were moderately positively correlated. Genetic variability of metallicolous and non-metallicolous populations was not significantly different. Lowland populations were clearly differentiated from the alpine populations. Within the lowland group metallicolous and non-metallicolous populations were not genetically differentiated. All lowland populations show a regional differentiation and close relationships to ssp. elongata. Thus, the metallicolous taxa should not be maintained as subspecies. Likewise, their treatment as varieties of a ssp. halleri s.l. is critical because this taxon cannot be consistently characterized throughout its geographical range and may be an artefact itself. If a taxonomical recognition should be considered necessary it is advisable to treat the microendemics as varieties of ssp. elongata.
