Why would it n«t be a godd time while you are abandoning the Kew Bule 

 taking up the "double headed citations" as Watson used to call them, 

 to wave one more flag of truce and take up pi?yopteris instead of the 

 much later Nephrodim which was not properly published in that Oarda- 

 ening list ( Hort.Mod, etc) anyway^and must date as a first publication 

 from the melange in the Pl.Bor, Am. ? In this way you would not only 

 be in line with the rest of American usage except Clute--in whose com- 

 pany no one who has over had him in employ would care to have too much 



d« with but you would also be in harmony with present Berlin 



usage{as seen in UPban's Flora of Puerto Ric#) and CJhristensen's 

 index Pilicum which is to supplant the syn<>p^^^^ 



usage among the ferns tho it is no P
