Abstract
This electron microscopy study of Achnanthes brevipes from mineralized tributaries (Solyanka, Chernavka, Khara) of the hyperhaline Lake Elton (Volgograd Region) provides new data on the variability of quantitative diagnostic characteristics (valve length, number of striae and areolae in 10 μm). Based on the original and published data, a refined diagnosis of A. brevipes is proposed. It is very similar to A. longipes in valve shape and quantitative characteristics, but striae are multi-row in the latter species and single-row in A. brevipes. A short note about the nomenclature status of A. brevipes is given.
期刊介绍：
The Journal is one of the scientific periodicals of the Komarov Botanical Institute (at present belonging to the Russian Academy of Sciences), founded as the garden of medicinal plants by Peter the Great in February 1714. The Journal under the name Novosti sistematiki nizshikh rastenii was founded in 1964 by the botanists of the Komarov Botanical Institute, St. Petersburg (formerly Leningrad). It represents a continuation of Botanicheskie materialy Instituta Sporovykh Rastenii Glavnogo Botanicheskogo Sada RS FSR, Petrograd, vol. 1–4(7), 1922–1926; Botanicheskie materialy otdela sporovyh rastenii Botanicheskogo Instituta imeni V. L. Komarova Akademii Nauk SSSR, Moscow, Leningrad, vol. 5(4/6)–5(10/12), 1940–1945; vol. 6(7/12)–16, 1950–1963, preceded by Botanicheskie materialy Otdela sporvykh rastenii Botanicheskogo Instituta Akademii Nauk SSSR, Moscow, Leningrad vol. 6(1/6), 1949. The Journal publishes original papers on taxonomy, systematics and biodiversity of algae, fungi, lichens and bryophytes.
