The article examines the genetic diversity in 54 populations of 9 Chondrilla species (C. acantholepis, C. ambigua, C. brevirostris, C. canescens, C. graminea, C. juncea, C. laticoronata, C. latifolia, and C. pauciflora) in European Russia. Plastid DNA segments trnT–trnF are selected as markers. Reconstruction of evolutionary networks based on the principle of maximum parsimony reveals that the sample is divided into four groups, where group 1 is C. ambigua, 2 – C. brevirostris, 3 – C. laticoronata, 4 – C. acantholepis, C. canescens, C. graminea, C. juncea, and C. latifolia. The findings show that C. acantholepis, C. canescens, C. graminea, C. juncea and C. latifolia are to be treated as synonyms under the name of C. juncea.
