Supporting Material: Character tables for families of the non-arboreal, spring-flowering flora of the eastern Piedmont of North Carolina

A multi-access key (MAK) is a data set in which each taxon is evaluated for each character in the key. MAKs can facilitate plant identification because they allow users to select characters for identifications. A recent study found that inexperienced users did not benefit from the character choice feature of a MAK but suggested that more experienced users might benefit. All of the tables of the MAK to the spring-flowering, non-arboreal flora of the eastern Piedmont in North Carolina used in the study were not previously published due to space constraints in the printed journal (J. North Carolina Acad. Sci.). The purpose of the current article is to present an alphabetical list of all sixty-six plant families in the MAK, explanations of all characters and character states, a list of character states, each of which occurs in few families, and the thirteen character tables.
