Baccharis s.l.: infrageneric relationships? ? Given the great diversity and wide geographic distribution of Baccharis, the recognition of smaller and morphologically well-circumscribed infrageneric groups is critical to achieve strong advances in taxonomy

Baccharis s.l.: infrageneric taxonomy Candolle (1836): 8 sections �Followed by Weddel (1855), Baker (1882) and Hoffmann (1890) Gray (1886): 4 informal groups � Influenced Heering (1903, 1904a, 1904b): 5 subgenera, several sections and subsections Cuatrecasas (1967, 1982): circumscription of 24 sections based mainly on Colombian species �Influenced Ariza (1973), Nesom (1988, 1990), Giuliano (2001, 2005) and Giuliano & Nesom (2003) Barroso (1976): 15 informal groups, similar to the sections of Cuatrecasas Müller (2006): 4 subgenera with several informal groups and 3 groups not ascertain to a subgenus Giuliano (2011): followed Müller subgenera, described 15 new sections + 3 new combinations to section level ***several sections and groups are monotypic*** Search for all infrageneric names published Provisional placement into the described subgenera, sections, subsections, series and informal groups for further testing of monophyly of the proposed groups
