<SO GENERIC RULES. 



and in remote places ; Avhere they happen occa- 

 sionally to clash by applying similar names to 

 distinct Genera, either discovered or reformed : 

 While they may also give different names to a 

 single Genus. 



Else Me may have double and triple names for 

 similar Genera, as was the case with those of 

 Aublet, changed by Necker and Schreber. It 

 is not yet perfectly settled which are to prevail, 

 many of Aublet were barbarous ; but others 

 quite good and easily latinized. This difficulty 

 will always occur, unless we stand by the rule 

 of always admiting the previous name, if good 

 or even tolerable. 



The names of some Botanists happen some- 

 times to be given to several Genera, because 

 many wish to reward their labors: while others 

 are left unrequitted for years. I was very prone 

 to dedicate such Genera ; but now always add 

 a second name as a substitute in case of pre- 

 vious application. 



There have been for instance, 4 Genera call- 

 ed Scopolia, the first in time of Jaquin was found 

 to be a Hyosciamus. The second of Linneus 

 jun. has since been united to Daphne, altho' it 

 has capitate flowers with a perianthe or invo- 

 lucre, and must at least form a subgenus. 

 Forster made the .3d, but deeming since the 2d 

 good, he changed his to Griselinia. The 4th 

 was made by Smith, by changing the good name 

 Todalia of Jussieu ; a very improper change, 

 yet imitated by Schreber who made it Cranizia, 

 but there was a previous Qrantzia of Swartz! 

 Todalia is better than Coffea of Linneus and 

 must be preserved as previous. Thus Scopolia 

 has been multiplied and made doubtful, unless 

 we restore it to the 2d as a genus or subgenus.
