ж Phyllitis being under the “Vienna Rules" and the “ Brussels Amendments” the 
legal name for. the genus of ferns usually known as Scolopendrium, Nordstedt has (loc. 
cit.) decided that Ilea, i nus of Ulvaceae, should be taken up for the 
genus of brown algae currently known as аз Phyllitis. This procedure, in spite of the 
confusion m it would entail, may be justifiable under the prevailing European rules 
of nomenclature, but the earlier use of Пеа in an entirely different sense happily 
forbids it under the “rejection of homonyms” principle of the “American Code.”
