2025
Řepka, Radomír | Řepka, Jan
The article presents three Carex nothospecies new to the flora of the Czech Republic found in 2024 directly in the field and through revision of specimens in the larger Czech herbaria. We found Carex x felixii (= C. acutiformis x C. elata) at two localities and five more records by revising herbarium specimens. Carex x prahliana (= C. lasiocarpa x C. rostrata) was found at three sites, and Carex x viadrina (= C. buekii x C. cespitosa) is now also known from three localities. In addition, we publish here six more records of Carex x alluvialis, a hitherto missing hybrid in the Czech Republic, which we found at two localities, while the other records are the result of a revision of herbarium specimens. The text of the article is accompanied by photographs of plants found in the field.
