56 Amendment and completion of 



[The very great number of descriptions published in languages 

 other than Latin prior to 1908, the manifest indisposition of many 

 authors to regard Article 36 as desirable, and the progressive dis- 

 use of Latin in educational institutions and scientific literature, 

 make this amendment necessary,] 



5. Motion to amend Article 39 by omitting the words : ** On 

 and after January ist, 1908, the date of publication of the latin 

 diagnosis only can be taken into account in questions of priority/' 



[The remarks under Article 36 apply to Article 39 as well.j 



6, Motion to amend Article ^S so that it shall read : 



A genus or any other group of higher rank than a species is 



effectively published when its name has been printed and distributed 

 (i) with a generic or specific description (or in paleobotany a fig- 

 ure) and a binomial specific name, or (2) with a generic name and 

 the citation of a previously published description, or (3) with a ref- 

 erence to a specific description which is associable by citation with 

 a previously published binomial species. 



' Examples. — Hydrodictyon Roth, Tent. Fl. Germ. 3 : 531 (1800), is published 

 with a generic and specific description and a binomial specific name; Odontoschisma 

 Diimort. Rec, Obs. Jung. 19 (1835) is published with a generic description and a 

 binomial specific name ; B7'asenia Schreb. ex GmeL Syst. 2 : 853 (1791) is published 

 with a generic description and a binomial specific name ; Poacites Schloth. Petrefact. 

 416. pL 26, fu 7", 2 (i820)j a fossil genus, is published with figures and a binomial 

 specific name, but without a description ; Nyssa L. Sp. PL 1058 (1753) is published 

 with a generic and specific name and the citation of previously published descriptions ; 

 Acetabulum Ludwig, Def. Gen. PI, 504 (1760), a genus adopted from Tournefort, is 

 published with a reference to a specific description associable by citation with the pre- 

 viously published Madrepora Acetabulum L. Syst. Nat. 793 (1758), inasmuch as both 

 Ludwig and Linnaeus cite Acetabulum of Tournefort ; Dryopteru Adans, Fam. PL 2 : 

 20 (1763) IS published with a reference to a specific description associable by citatioa 

 with the previously published Polypodium Filix-mas L. Sp. PL 1090 (1753), ^"^s- 

 much as both Adanson and Linnaeus cite Filix ?nas of Fuchs.

out a generic description, should not be extended to subsequent 

 authors. These genera, if typified, are just as definite as pages 

 of generic descriptions would make them. Philosophically, a 

 genus is a group of one or more species rather than a description. 

 There are a great many published descriptions of genera, unac-
