IV. WliiMi tlie iiaiiii» (if a jjiMius, suligemis or sertiou is taken froni tlie nnme of a persoii, 

 it is fiirini'd iii tlie foUowing iiianilfr: 



<0 WliPii the name ends in a vowol. tlif letter a is added (for oxaniple GUizioiia after 

 tilaziou; Bureaim after Bureau), except wlieu the nauie already ends in a. in wliiili ease ca is added 

 (e. g. Col/aea after Colla). 



*) When the nanie ends in a eonsonant, the letters w are added (tims A/agjuisia after 

 Magnus; Ramoiidia after Raniond), excejtt when the name ends in er, in which case a is added 

 (e. g. Kiinera after Kerner). 



■ ) The spelling of the syllables unaffected hy thèse finals is retnined, even whilli the 

 consunants l: and w or with gronpings of vowels which were not nsed in classic latin. Letters 

 which are unknown to botanical latin nnist be transcribed, diacritic signs are suppressed. The gernian 

 U, Ö, ii beconie ae, oe, ne, the French é, t" and ê beconie generally e. 



d) Xanies may be acconipanied by a prefix, or a snffix, or nindified by anagram or 

 ahbreviation. In thèse cases they count as différent words from the original name. E. g. Durvillea 

 and Urvillea, Lapeyrousea and Peyrousea, Englera, EngUiastrum and Engkrella, Botidteu and Cboc/ifa. 

 Cerardia and Graderia, Martia and Martiusia. 



V. Botanists who are pnblisliing generic names show judgement and taste liy attending to 

 the following recommendations: 



a) Not to make names very long or difficnlt to pronounce. 



i) Not to nise again a name which bas already been nsed and bas lapsed into syuonymy 

 (lumuinym). 



c) Not to dedicate gênera to ]iersons who are in ail respects strangers to botany. or at 

 least to natural science, nor to persons quite unknown. 



d) Not to take names froin barbarous tongnes, unless those imnu's are frecpiently ipioted 

 in books of travel, and bave an agreeable form that is readily adaptinl to the latin tonaue and to 

 the longues of civilized countries. 



.) To recall, if possible, by the formation lu- ending of tbi- name, the affinities or the 

 analogies of the genus. 



/) To avoid adjectives nsed as nouns. 



g) Not to give a genus a name whose form is rallier that of a subgenus or section (e. g. 

 Eusideroxylon, a name giveii to a genus of Lauraceae, which, however, being valid, cannot be cbanged). 



h) Not to make names by the comhination of two langn.ages (nomina hybnda). 



VI. Botanists constructing names for snbgenera or sections, will do well to attend to the 

 preceding recommendations and also to tlie foUuwing: 



<;) (iive, wbere possible, to the principal division of a genns, a name which, by sonn- modi- 

 ficatiuu or addition, calls the genus to mind (for instance. Eu placed at the lieginning of the name, 

 when it is of greek origin; -astrum, -ella at the end of the name, when latin, or any otber modi- 

 fication consistent with the grannnar and usages of tlie latin langnagel. 



b) Avoid calling a subgenus or a section by the name of the genus to which it belongs, 

 with tlie final -oïdes or -opsis; on the contrary réserve this ending for a section which resenibles 

 another genus, by adding in that case -oides or -opsis to the name of that other genus, if it is of 

 greek origin, to form the name of tlie section. 



c) Avoid taking as the name of a snbgenus or section a name wbieh is already in use as 

 such in another genus, or which is the iiame of an admitted genns.
