For the first time, the n ‐alkane distribution and variability of the epicuticular waxes within 22 Sedum taxa was reported with focus on the chemotaxonomy of native Sedum representatives from the central Balkan Peninsula, compared to their relations with four other species of the Crassulaceae family. By GC/MS and GC‐FID identification and quantification, it was established that n ‐alkanes C 27 , C 29 , C 31 , C 33 , and C 35 were the dominant constituents of the examined epicuticular wax samples. Applying multivariate statistical analyses including agglomerative hierarchical clustering (AHC) and principal component analysis (PCA), the relation according to the n ‐alkane composition between the examined samples was established. It was shown that the n ‐alkane variability of the central Balkan Sedum species was considerable and that n ‐alkanes might not be very reliable taxonomic markers for these species.
