Triterpenoid distribution in epicuticular waxes of 20 central Balkan Sedum L. species and four out‐groups of genera: Hylotelephium H. Ohba , Crassula L., Echeveria DC., and Kalanchoe Adans . were investigated for chemotaxonomic purposes. Identification and quantification of wax triterpenoids were performed by GC / MS and GC ‐ FID analyses. Distribution of identified triterpenoids (oleanane, lupane, and taraxerane series), as a pattern in statistical analysis, indicated very good agreement with phylogeny and systematics, except members of series Rupestria Berger , in which case the distribution of triterpenoids did not support known classification in a satisfactory manner. According to the obtained clustering, Kalanchoe is shown as similar to Sedum samples, while the other out‐groups were clearly separated.
