RULES OF NOMENCLATURE 59 



(b) When the name ends in a consonant, the letters ii are added (thus Magnusii 



from Magnus, Ramondii from Ramond), except when the name ends in 

 -er when i is added (thus Kerneri from Kerner) . 



(c) The syllables which are not modified by these endings retain their original 



spelling, even with the consonants korwor with groupings of vowels which 

 were not used in classical Latin. Letters foreign to botanical Latin should 

 be transcribed and diacritic signs suppressed. The Germanic d, o, u be- 

 come ae, oe, ou, the French e, e, e become generally e. The diaeresis sign 

 should be used where required. 



(d) When epithets taken from the name of a person have an adjectival form they 



are formed in a similar way (e.g. Geranium Robertianum, Verbena 

 Hasslerana) . 

 XLI. The same provisions apply to epithets formed from the names of women. 

 When these have a substantival form they are given a feminine termination (e.g. 

 Cypripedium Hookerae, Rosa Beatricis, Scabiosa Olgae, Omphalodes luciliae). 



XLII. The specific (or other) epithets should be written in conformity with the 

 original spelling of the words from which they are derived and in accordance with 

 the rules of Latin and latinization. 



Examples: silvestris (not sylvestris) sinensis (not chinensis). 



XLIII. Specific (or other) epithets should be written with a small initial letter, 

 except those which are derived from names of persons (substantives or adjectives), or 

 are taken from generic "or vernacular" names (substantives or adjectives). 

 (Emended Amsterdam Botanical Congress, 1935. See page 61 for actions taken by 

 Second International Microbiological Congress, London, 1936 governing Bacteriolog- 

 ical Nomenclature.) 



XLIV. In the formation of specific (or other) epithets composed of two or several 

 roots taken from Latin or Greek, the vowel placed between the two roots becomes a 

 connecting vowel, in Latin i, in Greek o; thus menthifolia, salvifolia, not menthae folia, 

 salviafolia. When the second root begins with a vowel and euphony requires, the 

 connecting vowel should be eliminated (e.g. lepidantha). The connecting vowels ae 

 should be retained only where this is required for etymological reasons (e.g. caricae- 

 formis from Carica, in order to avoid confusion with cariciformis from Carex). In 

 certain compounds of Greek words no connecting vowel is required, e.g. brachycarpus 

 and glycylphyllus . 



Section 14. Gender of Generic Names 

 Art. 72. The gender of generic names is governed by the following regulations: — 



(1) "A Greek or a Latin word adopted as a generic name retains its classical 



gender. In cases where the classical gender varies, the author has the 

 right of choice between the alternative genders. In doubtful cases, general 

 usage should be followed." "The following names, however, whose classi- 

 cal gender is masculine, are treated as feminine in accordance with historic 

 usage: Adonis, Orchis, Slachys, Diospyros, Strychnos. Hemerocallis (m. in 

 Sp. PL: Lat. and Gr. hemercalles n.) is also treated as feminine to bring it 

 into conformity with all other generic names ending in is." (Emended 

 Amsterdam Botanical Congress, 1935.) See Van Eseltine, Jour. Bact., S6, 

 1933, 569, for discussion of the gender of generic names used for bacteria. 



(2) Generic names which are modern compounds formed from two or more Greek 



or Latin words take the gender from the last. If the ending is altered, 

 however, the gender will follow it, 



(3) Arbitrarily formed generic names or vernacular names used as generic names 



take the gender assigned to them by their authors. Where the original
