| dc.description | Lessingianthus Robinson (1988a: 939) is one of the largest genera of tribe Vernonieae Cassini (1819: 203), with 133 species distributed in South America including Argentina, Bolivia, Brazil, Colombia, Paraguay, Peru, Uruguay and Venezuela (Robinson 1999). The species are perennial herbs or shrubs with xylopodia, having medium or largesized heads and seriate-cymose synflorescences (Robinson 1999). The genus comprises the species initially placed in Vernonia sect. Lepidaploa (Cassini 1817: 66) Candolle (1836: 26) subsect. Macrocephalae Bentham (1873: 229). Lessingianthus can be distinguished from the remaining genera of the tribe by its apical anther appendages without glands, styles without basal node, cubic crystals on the ovary wall, and pollen type B (Dematteis 2006, Robinson 2007, Angulo & Dematteis 2010, 2014). The basic chromosome number of the genus is x=16, and the genus has the greatest number of polyploid species and the highest ploidy level within the tribe (Angulo & Dematteis 2012). Since the description of Lessingianthus (Robinson 1988a), there have been a few problems in its generic limits. The single modification carried out by Dematteis (2007) has been the transfer of Lessingianthus subgen. Oligocephalus Robinson (1988a: 949) to the genus Chrysolaena Robinson (1988b: 956). After that, taxonomic studies carried out in this genus have focused on the description of new species and the resolution of nomenclatural specific problems (Dematteis 2006, 2008, Borges & Dematteis 2008, Dematteis & Angulo 2010, 2012). Nevertheless, several species still included in Vernonia have not been examined and, consequently, their taxonomic positions remain uncertain. In this paper, after the intense herbarium revision of species still included in Vernonia, we conclude that an accepted species name, V. oxyodonta Malme (1932: 19), should be placed to the synonymy of L. glabratus (Lessing 1829: 294) Robinson (1988a: 943) because the type material of V. oxyodonta is morphologically referable to L. glabratus. All the other specimens recognized as V. oxyodonta constitute a separate species and, therefore, should be formally described as a new species. Additionally, one taxon previously placed in Vernonia as V. pseudoincana (Hieronymus 1897: 689) Cabrera (1999: 110) is transferred to Lessingianthus. | - |
