Stuckey provides a full and well-illustrated account of frontier botanist William Starling Sullivant’s contributions to botany. William Starling Sullivant (1803–1873) is perhaps best known for his contributions to bryology, the study of mosses and liverworts, which he conducted during the latter half of the nineteenth century. A resident of Franklinton and later of Columbus, Ohio, on the frontier of American life in the mid-1800s, Sullivant gained considerable recognition in this country and abroad for his accomplished work on the study of North American bryophytes. His contributions were in the form of exchanges of plant specimens, preparation of sets of exsiccatae, publication of scientific papers and books, and the development of an extensive correspondence with botanists throughout the world.
