摘要：

Dactylorhiza traunsteineri sensu lato is a highly variable, tetraploid aggregate of narrow-leaved marsh orchids with a poorly known distribution. The uncertain distribution is due to difficulties in identifying populations, especially in marginal areas. Populations from calcareous fens in the eastern parts of Sweden were analysed. Predictions concerning morphological differentiation and population structure were tested with multivariate discriminant analyses and by comparing individuals within populations in terms of diagnostic characters. Four possible taxa were considered: D. russowii, D. traunsteineri, D. traunsteineri spp. pycnantha and the variety pusilla. It was concluded that all populations investigated in eastern Sweden belong to one variable taxon, D. traunsteineri.
