TUE NOMEffCLATUllE OF PLANT FAMILIES 71 



The case o£ JtoxhurglnacecG versus Sfcmonacecs is even clearer. 

 The family Roxhuri/hiaccce was published by Wallich in 1832, and 

 it was not until 1879 that the name was changed to Stemouacecd. 

 Similarly GhailletiacecG antedates Dlchapcfalacew by many vears, 

 whether priority is reckoned from ])ublication with the suffix -cce or 

 with -acecB ; and GaRellacecc has priority over Wi)iteranacea\

The case of FlcoidacecE versus Tetragoniacece and AizoacecB is 

 not quite so simple. Ficoides Tourn. is a synonym of 3fesemhrya)i- 

 themum, and Ficdidea Dill, is Aizoon. Jussieu's name Flcdidew 

 was derived from the former : the French form was " les Ficoides," 

 and " Ficoide " was the vernacular name of Mesemhri/anthemuni 

 (Gen. 317). If family names endmg in -ece are accepted for purposes 

 of priority, then the family should be called Ficoidacew ; if, on the 

 other hand, the earliest family name in -acece is adopted, then it 

 becomes TetragoniacecB. AizoacecB is a synonj^ra in any case.
