was tenably published, a conviction which is supported by the following quotation 

 from Winslow's published letter (1. c, 1854) : 



" The name that has been applied to this tree by Professor Lindley, an English 

 botanist, is Wellingtonia gigantea" * * * 



"If the tree be a Taxodium, let it be called Taxodium Washingtonianum. If a new 

 genus, Washing to nia Californica." 



According to Article VI of the Rochester Code of laws adopted for botanical nomen- 

 clature, Winslow's Taxodium Washingtonianum is validly published by reason of his 

 having fulfilled the essential conditions of the following clause of Article VI : " Publi- 

 cation of a species consists * * * (2) in the publishing of a binomial with refer- 

 ence to a previously published species as a type." 



This is a common and expedient method employed by botanists in publishing new 

 names for plants found to have been previously characterized under synonyms, 

 which results in duplicate names in the same genus, and therefore often leaves a 

 plant without a tenable name. The method of referring to the "previously pub- 

 lished species as a type " is usually toprint such species' name and author in connec- 

 tion with the newly proposed name, and in such a way that the two designations 

 are seen to be presented as equivalents, the one to replace the other. 



Now, since Wellingtonia gigantea Lindley is a recognized "previously published 

 species," it would seem undeniable that Winslow's intention was to supplant Lind- 

 ley's name by Taxodium Washingtonianum — entirely, of course, because his American 

 patriotism preferred that an American monster tree should bear the name of an 

 American rather than that of an English general. It is maintained here that Wins- 

 low definitely pointed out the tree he had in mind by stating that Lindley had called 

 it Wellingtonia giganiea (an undisputably published name), and that he effected the 

 publication of Taxodium Washingtonianum for this tree by proposing this name as a 

 substitute for Lindley's name. 



In interpreting the fundamental object of the article cited for the publication of 

 species and applying it to all cases likely to arise, it would seem the duty of the 

 interpreter to abide by the principle involved in the law, and to be influenced rather 

 by the actual meaning of a describer's combined words than by his unfortunate lack 

 of technical procedure in description.
