Abstract:
The main aim of this research is to fill in the missing taxonomic information on Hedysarum L. for the new edition of “Flora of Uzbekistan”. Currently, one of the main scientific areas of botanical research in Uzbekistan is a fundamental project to prepare a new edition of the Flora of Uzbekistan. More than 50 years after the first edition of the national flora, new volumes of the second edition of the "Flora of Uzbekistan" were published, which continues the best traditions of the classical floras of Central Asia. The previous edition of the “Flora of Uzbekistan” was the first detailed summary of the vascular plant species of the Republic, which in many respects surpassed similar "Flora" of neighboring countries. This fundamental work, once awarded the prestigious scientific prize named after Abu Raykhan Beruni, included information on 4148 plant species of the flora of Uzbekistan (of which 3663 are native and 485 are introduced). Since 2016, the first three volumes of the new flora have been published, which marks the beginning of a new stage in the study of the plant diversity of Uzbekistan. A large international team, including a number of Russian botanists, is involved in the implementation of the fundamental project "Flora of Uzbekistan". At the moment, the revision of some polymorphic families, such as Fabaceae, Apiaceae, Caryophyl-laceae, Brassicaceae, is ongoing, modern abstracts of these families with additions have been compiled, critical processing of a number of genera has been performed, as well as maps of the distribution of individual groups have been compiled on the basis of GIS. Particular attention is paid to the selection of type samples and typification. In the family Fabaceae, along with the polymorphic genera Astragalus L. and Oxytropis DC., critical processing of species of the genus Hedysarum L. is carried out. In the first edition of the Flora of Uzbekistan, E.E. Korotkova listed 19 species of this genus. Subsequent field studies and study of the National Herbarium of Uzbekistan (TASH) collection made it possible to identify 4 species new to Uzbekistan. In 2021, one new species was described. The main collection of TASH contains more than 1080 specimens of the genus Hedysarum belonging to 51 Central Asian species. Their first herbarium samples were collected by Karelin and Kirilov in 1841. And also, most of the herbariums of the genus were collected by M.G. Popov, V.P. Drobov, A.Ya. Butkov, E.P. Korovin, E.E. Korotkova, V.V. Lepeshkin, M.P. Tishchenko, N.P. Gomolitsky, M.M. Arifkhanova, M.M. Nabiev and others from 1915 to 1965. The paper contains an annotated list of type specimens of the genus Hedysarum from the Fabaceae family from Central Asia kept in TASH. For each taxon, the following is given: Latin name with reference to the publication of its original description; category of the type specimen(s); citation of label; citation from protologue; required notes (if any). Additional information and corrections made to the text of the label are given in square brackets. When typifying the names, the recommendations of the International Code of Botanical Nomenclature (ICBN), section “typification of taxa” were taken into account. Information about the types of both names accepted in the “Conspectus Florae Asiae Mediae” and online resources (http://www.worldfloraonline.org, https://powo.science.kew.org), and the names mentioned as synonyms are given. The spelling of the names and abbreviations of the surnames of the authors of the taxa are corrected according to the “IPNI. International Plant Name Index” (http://www.ipni.org). The names and authors indicated on the labels of herbarium specimens are quoted verbatim. Species are listed in alphabetical order. The names we have adopted in the list are in bold italics, while synonyms are in plain italics. During the revision of the genus Hedysarum, 71 type specimens of 27 taxa were identified from the TASH collection. The type specimens are represented by 11 holotypes, 20 isotypes, 20 paratypes, 5 lectotypes, 11 isolectotypes, and 4 specimina aut-entica. Lectotypes of 5 names: Hedysarum drobovii Korotkova (See Fig. 2), H. he-mithamnoides Korotkova (See Fig. 3), H. magnificum Kudr. (See Fig. 4) and H. baldshuanicum Fedtsch. are designated in the Herbarium TASH. In addition, holotypes stored in FRU (Institute for Biology of National Academy of Sci., Bishkek, Kyrgyzstan) for H. cumustchanicum (See Fig. 1) were given, because these holotype specimens were not presented in their initial description. The results of the research were applied in the preparation of a new volume of the Flora of Uzbekistan, dedicated to Fabaceae family.
