DOI 10.31489/2024bmg2/76-85
Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

In the article a complete list of specimens of species of the genus Suaeda Forssk. ex J.F. Gmel. of the Aral-Balkhash region, stored in the herbarium fund of the Institute of Botany and Phytointroduction (Almaty, Kazakhstan) was provided. Suaeda species are divided into 5 sections (Schanginia C.A. Mey, Lachnostigma Iljin, Conosperma Iljin, Physophora Iljin, Heterosperma Iljin). The aim of the research was to critically study the specimens of species of the genus Suaeda of the Aral-Balkhash region, available in the Herbarium (AA) for further revision of the genus. This territory includes 5 floristic regions (14 — Aral Sea, 15 — Kyzylorda, 16 — Betpakdala, 17 — Muyunkum (Moiynkum) and 18 — Balkhash-Alakul.). During the screening of species of the genus within the study region, 240 herbarium specimens were reviewed, belonging to 15 species. A comparison of the representation of species in the collection fund of the Herbarium with the data of literary sources was carried out. Floristic areas have been identified in which, despite the availability of information about the presence of the studied species on their territory, there is no herbarium material. At the same time, floristic areas are noted in which the presence of certain species of Suaeda was not previously cited in literary sources, but they are present in the collections of the Herbarium. The degree of study of each region was determined for the further compilation of the current expedition route in order to replenish the herbarium fund. The paper presents a synopsis of the studied group of species with an information block of herbarium labels for each taxon. The features of the distribution of Suaeda species of the Aral-Balkhash region in 5 floristic regions with an indication of the number of specimens for each taxon are revealed.
