24 LAWS OF NOMENCLATURE. 



Art. 23. The names of suborders (subordmes, sub- 

 familice) are derived from the name of one of the 

 genera that form part of them, with the final -ecB. 



Art. 24. The names of tribes and subtribes are 

 taken from that of one of the genera included in the 

 group, with the final -ece or -inece. 



§ 4. Names of Genera and of Divisions of Genera. 



Art. 25. Genera, subgenera, and sections, receive 

 names, commonly substantive, which may be compared 

 to our own. proper family names. 



These names may be derived from any source what- 

 soever, and may even be arbitrarily imposed, under 

 the restrictions mentioned farther on. 



Art. 26. A name may be given to subsections, as 

 well as to inferior generic subdivisions ; or these may 

 simply be indicated by a number, or by a letter. 



Art. 27. When the name of a genus, subgenus, or 

 section is taken from the name of a person, it is com- 

 posed in the following manner : — 



The name cleared of titles or of any accessory par- 

 ticle, takes the final -a or -ia. 



The spelling of the syllables unaffected by this final, 

 is preserved without alteration, even with letters or 

 diphthongs now employed in certain languages, but 

 not in Latin. Nevertheless «, o, and u, of the German 

 language become <?, «, and ue, whilst e and e of the 

 French language become e. 



/^RT. 28. Botanists who have generic names to pub- 

 lish show judgment and taste by attending to the fol- 

 lowing recommendations : — 



, (1.) Not to make names too long or difficult to pro- 

 nounce. 



(2.) To give the etymology of each name.
