The basionym of Eucladium verticillatum ( Pottiaceae )

Evidence is provided that the first person to validly publish a name for the species that Linnaeus termed “ Bryum verticillatum ” in 1753 was Withering in 1801, and that his name actually constitutes the basionym of the well‐known moss name, correctly cited as Eucladium verticillatum (With.) Bruch & Schimp. ( Bryophyta , Pottiaceae ). “ Weissia verticillata (Hedw.) ex Brid.” of 1801, which has hitherto been considered the basionym of this binomial, is a nomen nudum ; the combination Weissia verticillata was validly published by Bridel in 1806. Bryum verticillatum With. is lectotypified here with a specimen from Cumberland, England, that is preserved at BM.
