“…Pollen morphological data for taxa within the Stryphnodendron clade and outgroups were collected from herbarium specimens (CEN, ESA, and SPSC; acronyms following Thiers, [continuously updated]) and literature sources (Braga et al, 2012;Buril et al, 2010;Caccavari, 2002;de Freitas Cruz et al, 2018;El Ghazali et al, 1997;Flores-Cruz et al, 2006;Irian et al, 2013;Jumah, 1991;Kenrick and Knox, 1982;Lima et al, 2008;Luz et al, 2013;Medina-Acosta et al, 2019;Ribeiro et al, 2018;Santos-Silva et al, 2013;Barth and Yoneshigue, 1966;Barth, 1973Barth, , 1974Bauermann et al, 2009). We also collected data from Guinet and Caccavari (1992), who clustered species together in 'pollen types' according to their pollen traits.…”
