GENERAL SYSTEMATIC BACTERIOLOGY 127 



b. When the name ends in a consonant, the letters ii are added (thus Magnitsii 

 from Magnxis: Ramondii from Ramond), except when the word ends in er when i 

 is added (ex. Kerneri, from Kerner). 



c. Syllables which are not modified by these endings retain their original spell- 

 ing, even in the case of the consonants k and w or groupings of vowels which are 

 not used in classic Latin. Letters foreign to the Latin of botanists should be 

 transcribed, and diacritic signs suppressed. The German a, 6, ii, become ae, oe, 

 ue, the French e, e and e become, in general, e. 



d. When specific names taken from the name of a person have an adjectival 

 form a similar plan is adopted {Geranium Roberiianum, Car ex Holler ana, Ranun- 

 culus Bureauanus, etc.). 



Xn. The same applies to the names of women. These are written in the 

 feminine when they have a substantival form. 



Example: Cypripedium Hookerae, Rosa Beatricis, Scabiosa Olgae, Omphalodes 

 Luciliae. 



XIII. In the formation of specific names composed of two or several roots and 

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

 connecting vowel, in Latin i, in Greek o; thus we write menthifolia, salviifolia, not 

 menthaefolia, salviaefolia. When the second root begins with a vowel and 

 euphony demands, the connecting vowel is eliminated (e.g., calliantha, lepidan- 

 tha). The connecting ae is legitimate only when etymology demands (e.g., 

 caricaeformis from Carica, may be retained along with cariciformis from Carex). 



XIV. In forming specific names, botanists will do well to note the following 

 recommendations : 



a. Avoid very long names and those which are difficult to pronounce. 



Comments. A few specific names vi^hich have been applied to bacteria 

 seem to transcend good usage, but this of course does not invaHdatethem. 

 Among such long specific names which have been applied may be noted 

 the following: saccharobutyricus, heminecrobiophilus, diphtheriae-colum- 

 horum, viridi-pallescens, endoparagocicum, melanoglassophorus. 



b. Avoid names which express a character common to all or nearly ail the 

 species of a genus. 



Comment. Among such names are the followiag: Streptococcus 

 sphericus and Albococcus albus. These names ane, of course, valid. 



c. Avoid names taken from little known or very restricted localities, unless 

 the species be very local. 



Comment. Azotobacter vinelandii named after a locality in New 

 Jersey is scarcely in conformity with this recommendation, but is, of 

 course, not invalidated by this fact. 



d. Avoid, in the same genus, names which are very much alike, especially 

 those which differ only in their last letters.
