Аннотация: The problem of cryptic species is well known in taxonomy of different groups of organisms,including plants, and their recognition can contribute to the assessment of global biodiversity andthe development of conservation methods. Analyses of Lotus glareosus and related taxa from theIberian Peninsula based on various types of data (i.e. sequences of nuclear ribosomal ITS-1-2,5’ETS and cpDNA trnL-F, seven loci of nuclear microsatellites) revealed that the material earlierdetermined as ‘L. glareosus’ is subdivided into two genetically distant groups: L. carpetanus, relatedto L. conimbricensis, and L. glareosus, included in the L. corniculatus complex. Though only slightmorphological distinctions were found between them, significant genetic differences comparable tothose between sections of the genus Lotus (p-distance 0.07– 0.08 in ITS, 0.060 – 0.067 in ETS and0.010 – 0.013 in trnL-F; substitution number 43 – 47 bp in ITS, 22–24 bp in ETS and 12–14 bpin trnL-F) and no evidence of genetic exchange suggest that these groups may represent two deeplydiverged lineages that should be treated as two separate species. This example corresponds to theconcept of cryptic species. Based on molecular study of type specimens of L. carpetanus, we proposeto reestablish this name, previously synonymized with L. glareosus.
