The competing names for this well-known naturalised British 

 plant have often been discussed, but there still remains something 

 to be said. Veronica Buxhaumii Ten. is the only one of these names 

 the meaning of which is absolutely indisputable. In vol. xlii. of this 

 Journal (1894) p. 253 its claims were defended by F. N. Williams 

 against those of V. Touryiefortii Gmel. and V. persica Poir. Unfor- 

 tunately his argument is based on the untenable premiss that both 

 the latter names refer to V.filiformis Sm., a totally different species 

 from Asia Minor which is never found naturalised in western Europe. 

 In what follows I shall attempt to prove that V. Tournefortii Gmel. 

 is a hopeless muddle of contradictory characters drawn partly from 

 earlier descriptions of V. Jiliformis and partly from V. Buxhaiimii. 

 The name is therefore inadmissible for either species and must be 

 rejected altogether in conformity with Art. 51 clause 4 of the inter- 

 national rules : " Everyone should refuse to admit a name when the 

 group which it designates embraces elements altogether incoherent, 

 or when it becomes a permanent source of confusion or error." This 

 rule is just as cogent as that enjoining the use of the earliest published
