The genus Navicula in ancient basins. I. Two novelties from the Black Sea
Methods – This study is based on both historical and recent samples. Recent sampling was performed along the Ukrainian (Crimea) coast. In addition, samples from the Black Sea, originally collected and studied by Proshkina-Lavrenko in 1948–1951 and only recently rediscovered, have been analyzed. Results are based on light and scanning electron microscopy examination. We compared line drawings of Mereschkowsky's taxon with illustrations of similar taxa focusing especially on Navicula pinnata Pant. and N. pennata A.W.F.Schmidt.
Key results – Comparison of line drawings of Mereschkowsky's taxon revealed no resemblance to N. pinnata. Micrographs of N. pennata illustrated in our paper indicated that any infraspecific relationship between Mereschkowsky's taxon and N. pennata is unlikely. Hence, we propose a new name, Navicula pontica stat. nov. for Mereshkowsky's taxon. In historical samples N. pontica was accompanied by a similar, however, sufficiently different, species, described as new for science: Navicula parapontica sp. nov.
Conclusion – Our study resulted in a status change of a taxon originally described as Navicula pinnata var. pontica. In addition N. parapontica was described as new for science. These results will facilitate future identification of both abundant Black Sea littoral diatoms.

Plant Ecology and Evolution (a continuation of Belgian Journal of Botany, incorporating Systematics and Geography of Plants) is an international journal devoted to ecology, phylogenetics and systematics of all 'plant' groups in the traditional sense (including algae, cyanobacteria, fungi, myxomycetes), also covering related fields such as comparative and developmental morphology, conservation biology, ecophysiology, evolution, phytogeography, pollen and spores, population biology, and vegetation studies. It is published by the Royal Botanical Society of Belgium and the Botanic Garden Meise and contains original research papers, review articles, checklists, short communications and book reviews.
