| Popis: | Robert E. Regel was the first to comprehensively analyze the diversity of cultivated barley in Russia and identify more than fifty new subvarieties. Some of them he published in two articles: «Barleys with smooth awns» (1908) and «The most important varieties and races of barleys in Russia» (1910). The present study was carried out because no one has yet conducted a search for authentic herbarium specimens and lectotypified the Hordeum taxa described by R.E. Regel. We have found that the main collection of the Herbarium of cultivated plants of the world, their wild relatives and weeds (WIR) contains the authentic herbarium specimens of nine barley taxa described by R.E. Regel, namely Hordeum distichon var. erectum subvar. anglicum R. Regel, H. distichon var. nigricans subvar. vilmorenianum R. Regel, H. distichon var. nutans subvar. europeicum R. Regel, H. distichon var. nutans subvar. turkestanicum R. Regel, H. distichon var. nutans subvar. сolchicum R. Regel, H. vulgare var. nigrum subvar. taganrocense R. Regel, H. vulgare var. pallidum. subvar. Lapponicum R. Regel, H. vulgare var. pallidum subvar. praecox R. Regel, and H. vulgare var. ricotense subvar. kiarchanum R. Regel. Since the available herbarium sheets contain later reproductions of the collection specimens cited in the protolog, these herbarium specimens were chosen by us as neotypes. |
