ABSTRACT

A taxonomic list of Charales in southwest Ukraine (including original and literature data) with synonyms, distribution in Ukraine, and general distribution is given. The list contains 16 species from the genera Chara L. (13), Lamprothamnium J. Groves (1), Nitella C. Agardh (1), and Nitellopsis Hy (1). Recently, ten species have been found in the investigated territory including three new records: Chara connivens Salzm. ex A. Braun, Ch. uzbekistanica Hollerb., and Nitella mucronata (A. Braun) Miq. in H.C. Hall. However, Chara braunii C.C. Gmelin, Ch. contraria A. Braun ex Kütz., Ch. fragilis Desv. in Loisel., Ch. horrida Wahlst., Ch. tenuispina A. Braun, and Ch. schaffneri (A. Braun) Allen known from previous publications have not been found again. The growth areas of Ch. aculeolata Kütz. in Rchb., Lamprothamnium papulosum (Wallr.) J. Groves, Nitellopsis obtusa (Desv. in Loisel.) J. Groves, and Chara canescens Desv. et Loisel. in Loisel. (the Red Book of Ukraine species) have strongly been reduced. Changes in the flora of Charales in southwest Ukraine have probably been caused by anthropogenic impact and a general increase of salinity in inland water bodies of the investigated territory.
