The author of the monographs, Joannes Lehmann (1792-1860), was professor at Hamburg University from 1818 and director of the botanical garden. The books are inscribed by the author to his respected peer, Professor Fredrik Wahlberg (1800-1877), a Swedish botanist, pupil of Carl Thunberg and member of the Swedish Academy of Sciences. Wahlberg was appointed professor of natural history and Materia Medica at the Karolinska Institute. A neat manuscript note by Wahlberg listing species is loosely inserted.
