Nowe i rzadkie dla flory Polski gatunki okrzemek
Abstract
Taxonomic and ecological analysis of 21 diatom species was carried out. 13 of
them have not been recorded in Poland until the present study; they are: Amphora montana
Krasske, Navícula erifuga Lange-Bertalot, N. goeppertiana (Bleisch) H. L. Smith, N.joubaudii
Germain, N. libonensis Schoeman, N. oppugnata Hustedt, N. novaesiberica Lange-Bertalot,
N. recens (Lange-Bertalot) Lange-Bertalot, N. stroemii Hustedt, Neídíum bisculatum var. subamplialum
Krammer, Pinnularia ignobilis (Krasske) Cleve-Euler, Stauroneis lauenburgiana Hustedt,
St. wislouchii Poretzky & Anisimowa. 11 of these taxa (underlined) as well as Caloneis latiuscula
(Kützing) Cleve and C. molaris (Grun.) Krammer are rare species for Polish and world diatom
floras. 6 taxa have been described due to changes in their nomenclature introduced by Lange-Bertalot (1986, 1993), and new localities of their occurence in Poland are also given. These
species are: Caloneis alpestris (Grun.) Cl., N. laterostrata Hust., N. rynchocephala Kütz.,
N. rynchotella Lange-Bertalot, N. subminuscula Manguin and Pinnularia stomatophora (Grun.) Cl.
