Dear all, We may be beating the proverbial D. H. But all this confusion might be cleared by the addition of one word. : "NOW" I just sent a note to PB labelled "WAS xyz; NOW abc'. Still using two species names might raise eyebrows such as "Was Allium A, Now Allium B" and the reader might still think this was a species name change, not just a subject change. An age of confusion. Best Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd. Kansas City Missouri 64152-2711 USA Ph. 816-746-1949 Zone 5 Record low -23F Summer 100F +
