HISTORY OF BOTANY. 65 



12. A generic name, to which is prefixed one or more 

 syllables, so as to alter its signification, and render it 

 applicable to other plants is not admissible; as Bulho- 

 castanum, Cynocrsimbe, ChamcBnenum. 



13. Generic names ending in " oides " are to be rejected ; 

 as kgrimonoides, Asteroides, &c. 



14. Generic names formed of other generic names, with 

 the addition of some final syllable, are disagreeable, as 

 Aceiosella, Balsamic, 'R2i]}istrum, &c. 



15. Generic names sounding alike lead to confusion. 



16. No generic names can be admitted except such as are 

 derived from either the Greek or Latin languages. 



17. Generic names appertaining previously to Zoology, 

 or other Sciences, are to be cancelled, if subsequently 

 applied in Botany. 



18. Generic names at variance with the characters of any 

 of the species are bad. 



19. Generic names the same as those of the class or order 

 cannot be tolerated. 



20. Adjective generic names are not so good as substantive 

 ones, but may be admitted. 



21. Generic names ought not to be misapplied to gaining 

 the goodwill or favour of saints or persons celebrated in 

 other Sciences ; they are the only reward that the botanist 

 can expect, and are intended for him alone. 



22. Nevertheless, ancient poetical names of deities or of 

 great promoters of the Science are worthy of being retained. 



23. Generic names that express the essential character or 

 habit of a plant are the best of all. 



24. The ancient names of the classics are to be respected. 



25. We have no right to alter an ancient generic 

 name to one more modern, even though it may be for the 

 better : this would in the first place be an endless labour, 

 and in the next place would tend to inextricable confusion.
