Since this initial visit, McVaugh has been a steadfast supporter of the project, especially in connection with the treatmentforNuevaGalicia(Mickel,1992).Inadditiontobeingquiteknowledgeableaboutferns himself,hehasbeentirelessinthecollectionandidentificationofMexicanpteridophytes.Onthat same 1957 trip, the senior author and McVaugh became acquaintedwithJerzyRzedowski,whose interest and assistance in our collecting and herbarium studies, as well as his abundant fern col- lections, have been invaluable in the completion of this flora. It is with great appreciation and warmaffectionthatwededicatethisbooktothesetwogiantsofMexicanbotanyandfloristics.
