Art. 41. An altération of the constituent cliaracters oi- of the circumscription 

 of a group does not warrant the quotation of another author than the one who first 

 pulilished the name or combination of names.

 pro parte, or excl. gen., excl. sp., excl. var., or some other abridged indication, are 

 added after the citation of the original author, according to the nature of the changes 

 that hâve been made, and of the group in question.

 liiria cordifolia L. excl. var. /?. ; etc. 



Art. 42. When a manuscript name lias been published and referred to its

Recommendations. 



XXV. Aulbcirs' names put after names of jilants are abbreviated, unless they are very short. 



For this jniqjose preliminary partiales or letters that do not, strictly speaking, form part 

 iif tlie name, are suppressed, and the first letters are given without any omission. If a name of one 

 syllable is long enough to make it worth while to abridge it, the first consonants only are given 

 (Br. for Brown); if the name bas two or more syllahles, the first syllable and the first letter of the 

 following one are taken, or the two first when both are consonants (Juss. for Jussieu; Rieh, for 

 Richard). WTien it is necessary to give more of a name to avoid confusion between names beginning 

 with the same syllaliles, the same System is to be followed. For instance two syllahles are given 

 together with the one or two first consonants of the third; or one of the last characteristic consonants 

 of the name is added (Bertol. for Bertoloni, to distinguish from Bertero; Michx for Michaux, to 

 distinguish from Micheli). Christian names or accessory désignations, serving to distinguish two 

 botanists of the same name, are abridged in the same way (Adr. Juss. for Adrien de Jussieu, Gaerln. 

 fil. or Gaertn. f. for Gaertner filius).
