Scientific names should be given the Latin names of each species in full, together with the source for its name, at first mention of the name in the main text. Subsequently, the genus name may be abbreviated, except at the beginning of a sentence. If there are many species, cite a Flora or provide a checklist which may be consulted when needed instead of listing them in the text. Do not give authorities for species cited from published references. Give priority to scientific names in the text (with colloquial names in parentheses, if desired).
