ASTERACEAE

Phylogenetic investigations on the Coreopsideae (Kim et al., 1999; Crawford et al., 2001, 2009; Kimball & Crawford, 2004; Crawford & Mort, 2005; Mort et al., 2008) highlighted several genera, including Coreopsis L. and Cosmos Cav., within which Bidens L. is evidently nested, making it clear that we can not keep them separate. Both Bidens [1753] and Coreopsis [1753] have the same priority over remaining genera needing to opt for Bidens as that chosen by Baillon (1886), who first united them (Art. 11.5. of ICN). Concerning the Euro+Med area, two new names and eight combinations are shown below: four of the last already exist, the other are proposed here as new.
