The author of a name is not part of the name of a taxon, and its citation is optional in most types of publications. Author names should be used in a formal taxonomic publication for family and lower taxonomic levels. Omit the authors of names in texts for a general audience.
Author names at family level and lower are included in IPNI; they are represented, and often abbreviated, in a standardised format that is also available in IPNI. When citing the author name, do not use punctuation between the plant name and the author’s name. Represent the names exactly as they occur in IPNI:
Lissanthe R.Br.
[No spaces between the elements of the author’s name.]
Lissanthe scabra Crayn & E.A.Br.
[Do not replace the & with and; et can be used instead of &.]
Lissanthe rubicunda (F.Muell.) J.M.Powell, Crayn & E.A.Br.
[Cyathodes rubicunda F.Muell. was transferred to Lissanthe by Powell, Crayn and Brown; author of original name is retained in parentheses, and author of new name is added.]
Astroloma microdonta F.Muell. ex Benth.
[Mueller proposed the name but Bentham validly published it; set ‘ex’ in roman.]
