\"Ward<\/a>Thomas Walter and His Plants: The Life and Work of a Pioneer American Botanist<\/a>, <\/em>a new book from The New York Botanical Garden Press, documents how Walter named, for the first time, many native plants in North America in his Flora Caroliniana<\/em>, published in 1788. Part history, but mostly scientific, Thomas Walter and His Plants <\/em>will be of interest to botanists, bibliophiles, and history-of-science enthusiasts.<\/p>\n

Flora Caroliniana<\/a> <\/em>was the first flora written in America that used Carl Linnaeus’ classification system and binomial nomenclature. In terms of modern taxonomy, this is a very big deal. The way that plants are still named today has its basis in Linnaeus works, specifically his Species Plantarum<\/em><\/a>, published in 1753. After this publication, binomial nomenclature<\/a> became the standard for naming plants. Very simply, binomial nomenclature is a system of giving plants (and other living things) a Latin name containing two parts\u2014a genus (which is a capitalized noun) and a specific epithet (which is a lower-cased modifying adjective, often descriptive or commemorative). (Read more about taxonomic ranks, including genera and species here<\/a>.) 
\n
\nBotanical nomenclature can be quite complicated, but the general idea behind the system is to provide stable names by giving priority to the earliest, validly published name.<\/p>\n

Thomas Walter was often the first person to apply binomial names to certain species, which means that Walter\u2019s names often have priority over more recent names applied to the same species by later botanists. The big catch is that Walter didn\u2019t leave behind plant specimens as representations of the species he was naming. When scientists find a new plant in the wild and want to give it a name\u2014naming a species new to science\u2014they should also collect that plant and preserve it as the physical evidence of what exact <\/em>plant they were looking at when they described the species. These are called type specimens. Because Walter didn\u2019t leave us a collection of type specimens, it\u2019s extraordinarily difficult to know with absolute certainty what exact species he was looking at when he was writing his descriptions and assigning names.<\/p>\n

For a taxonomist\u2014a botanist who groups plant species into categories, or higher ranks\u2014working with Walter\u2019s species names is a great opportunity to solve mysteries related to plant names in North America. The author of Thomas Walter and His Plants<\/em>, Dan Ward, was doing just that. Ward died before this book was published and before he had completed all the taxonomic work he had planned with Walter\u2019s names. However, Thomas Walter and His Plants <\/em>includes information about what species Ward believes Walter was naming, laying the foundation for future botanists to continue this taxonomic work.<\/p>\n

Anyone interested in the accurate naming of plants of the southeastern United States should read this book, as Ward has drawn a very careful roadmap with signs pointing to some of the taxonomic issues that have to be addressed. Perhaps a reader will even be inspired to continue his work.<\/p>\n
