Taxonomic notes
"Currently there are upwards of 30 species in the genus Ulnaria, with a number yet to be described (Williams pers. comm.) or still identified as species of Fragilaria Lyngbye (1819: 182) (Lange-Bertalot & Ulrich 2014 named some obvious species of Ulnaria as Fragilaria). Ulnaria is distributed worldwide but there are species and species groups that are restricted to just one area." (Liu, William & Tan 2017: 256). - (23 Nov 2017) - M.D. Guiry
