Wernham's and Sprague's <i>Manettia</i> (Rubiaceae) types

Abstract In the first decades of the twentieth century, Herbert Fuller Wernham and Thomas Archibald Sprague were both interested in the genus Manettia (Rubiaceae) and between them published 44 new Manettia species names, all but two of these in three publications. Wernham's principal publication was divided into two parts, the first third appearing in 1918 and the last two thirds in 1919, so most of his 34 new names appeared in 1918 and require typification. Sprague's 10 new species names and one resurrected specific name appeared in three publications in 1904 and 1905. The typifications of their new names are clarified, and any new typifications needed are made.
