A Nomenclator of Diplostephium (Asteraceae: Astereae): A List of Species with Their Synonyms and Distribution by Country

Abstract

Since the description of Diplostephium by Kunth in 1820, more than 200 Diplostephium taxa have been described. In the absence of a recent revision of the genus, a nomenclator of Diplostephium is provided based on an extensive review of the taxonomic literature, herbarium material, and databases. Here, 111 species recognized in the literature are listed along with their reference citations, types, synonyms, subspecific divisions, and distributions by country. In addition, a list of doubtful names and Diplostephium names now considered to be associated with other taxa is provided.
