Excerpt from Vascular Plants of the Black Hills of South Dakota and Adjacent Wyoming Taxa are arranged alphabetically by genera, and then alphabetically by species within genera. Varieties or subspecies follow species. For each taxon the appropriate alphabetical plant symbol is given, followed by the scientific name of the genera and species and the author ity; an alphabetical symbol for the scientific name of the family (and tribe for the Graminae and Compositae); and a life-form symbol. Alphabetical symbols have been determined as follows: For genera, the first five letters of the generic name; for species, the first two letters of the genus name and the first two letters of the species name (subspecies and varieties are indicated by including the first letter of the subspecific or varietal name in the symbol); for family, _ the first six letters of the family name (tribes are indicated by the parenthetical insertion of a three - letter symbol composed of the first three letters of the tribal name after the family symbol). Where symbols are duplicated, a number (starting with 2) is used as part of the symbol. Only capital letters are used for symbols.
