Fischer’s "Echinops dauricus" of 1812, a nomen nudum, was published twice independently in the same year, by Hornemann with the spelling "davuricus" and by Treviranus (Ind. Sem. Hort. Bot. Wratislav., App. 1: 2. 1819) as "dahuricus." We treat these two names as published simultaneously and give precedence to the former.
