The section  Multicaulia  is the largest clade in the genus  Hedysarum  L. (Fabaceae). Representatives of the sect.  Multicaulia  are valuable plants used for medicinal and fodder purposes. The taxonomy and phylogeny of the sect.  Multicaulia  are still ambiguous. To clarify the species relationships within sect.  Multicaulia , we, for the first time, explored repeatomes of  H. grandiflorum  Pall.,  H. zundukii  Peschkova, and  H. dahuricum  Turcz. using next-generation sequencing technologies and a subsequent bioinformatic analysis by RepeatExplorer/TAREAN pipelines. The comparative repeatome analysis showed that mobile elements made up 20–24% (Class I) and about 2–2.5% (Class II) of their repetitive DNAs. The amount of ribosomal DNA varied from 1 to 2.6%, and the content of satellite DNA ranged from 2.7 to 5.1%. For each species, five high confident putative tandem DNA repeats and 5–10 low confident putative DNA repeats were identified. According to BLAST, these repeats demonstrated high sequence similarity within the studied species. FISH-based mapping of 35S rDNA, 5S rDNA, and satDNAs made it possible to detect new effective molecular chromosome markers for  Hedysarum  species and construct the species karyograms. Comparison of the patterns of satDNA localization on chromosomes of the studied species allowed us to assess genome diversity within the sect.  Multicaulia . In all studied species, we revealed intra- and interspecific variabilities in patterns of the chromosomal distribution of molecular chromosome markers. In  H. gmelinii  Ledeb. and  H. setigerum  Turcz. ex Fisch. et Meyer, similar subgenomes were detected, which confirmed the polyploid status of their genomes. Our findings demonstrated a close genomic relationship among six studied species indicating their common origin and confirmed the taxonomic status of  H. setigerum  as a subspecies of  H. gmelinii  as well as the validity of combining the sect.  Multicaulia  and  Subacaulia  into one sect.  Multicaulia .
