We present an information about new findings of 11 vascular plant species on the Khamar-Daban Range (south of Eastern Siberia). Among them, three species (Festuca arundinacea, Neottia nidus-avis, Ranunculus grandifolius) are registered in Baikal Siberia for the first time. One species (Poa compressa) is recorded on the ridge for the first time. For other seven species (Botrychium anthemoides, Daphne mezereum, Fragaria x ananassa, Galium triflorum, Poa remota, P. x intricata, P. trivialis) new findings within the range are presented.
