Examples: Rosaceae (from Rosa), Salicaceae (from Salix), Caryophyllaceae (from Dianthus 

 Caryophylltis), etc. 



Art. 22. The following names, owing to long usage, are an exception to the 

 rule: Palmae, Gramineae, Cruciferae, Leguminosae , Guttiferae, Umbelliferae, 

 Laliatae, Compositae. 



Art. 23. Names of subfamilies {suhfamiliaè) are taken from the name of one 

 of the genera in the group, with the ending -oideae. The same holds for the tribes 

 {tribus) with the ending -eae, and for the subtribes {subtribus) with the ending -inae. 



Examples of subfamilies: Asphodeloideae (from Asphodelm), Rumicoideae (from Rumex)\ 

 tribes: Asclepiadeae (from Asclepias), Phyllantheae (from Phyllanthus)\ subtribes: Metastelmatinae (from 

 Metastelmd), Madiinae (from Madia). 



§ 3. Names of genera and divisions of genera. 



Art. 24. Genera receive names, substantives (or adjectives used as substan- 

 tives) in the singular number and written with a capital letter, which may be com- 

 pared with our own family names. These names may be taken from any source 

 whatever and may even be composed in an absolutely arbitrary manner. 



Examples: Rosa, Convolvulus,Hedysarum,Bartramia,Liquidambar, Gloriosa, Impatiens, Manihot. 



Art. 25. Subgenera and sections also receive names, usually substantives and 

 resembling the names of genera. Names of subsections and other lower subdivisions 

 of genera are preferably adjectives in the plural number and written with a capital 

 letter, or their place may be taken by an ordinal number or a letter. 



Examples. — Substantives: Fraxinaster, Trifoliastrum, Adenoscilla, Euhermannia, Archie- 

 racium, Micromelilotus, Pseudinga, Heterodraba, Gymnocimum, Neoplantago, Stachyotyptis. Adjectives: 

 Pleiostylae, Fimbriati, Bibracteolata, Pachycladae.

IV. When the name of a genus, subgenus or section is taken from the name of a person,^ 

 ti is formed in the following manner: 



a) When the name ends in a vowel, tiie letter a is added (for example Boutehua after 

 Boutelou; Ottoa after Otto; Sloanea after Sloan e), except when the name already ends in a, in which 

 case ea is added (e. g. Collaea after Colla). 



b) When the name ends in a consonant, the letters ia are added (thus Magnusia after 

 Magnus; Ramondia after Ramend), except when the name ends in er, in which case a is added 

 (e. g. Kernera after Kerner). 



c) The spelling of the syllables unaffected by these finals is retained, even with the 

 consonants k and w or with groupings of vowels which were not used in classic latin. Letters 

 which are unknown to botanical latin must be transcribed, diacritic signs are suppressed. The german 

 ä, Ö, Ü become ae oe, ue, the French é, è and ê become generally e. 



d) Names may be accompanied by a prefix, or a suffix, or modified by anagram or 

 abbreviation. In these cases they count as different words from the original name. E. g. Durvillea 

 and Urvillea, Lapeyrotisea and Peyrousea, Englera, Englerastrum and Englerella, Bouchea and Ubochea, 

 Gerardia and Graderia, Martia and Martiusia. 



V. Botanists who are publishing generic names show judgement and taste by attending 

 to the following recommendations: 



a) Not to maKC names very long or difficult to pronounce.
