A novel phylogenetic infrageneric classification of Baccharis (Asteraceae: Astereae), a highly diversified American genusWe present the hitherto most comprehensive phylogenetic hypothesis for Baccharis. Our results confirm that subtribe Baccharidinae is a monogeneric group and support a broad circumscription of Baccharis as monophyletic with the inclusion of all genera that have been previously segregated from it (Baccharidastrum, Baccharidiopsis, Heterothalamulopsis, Heterothalamus, Lanugothamnus). We provide comprehensive...

New circumscription, morphology and synopsis of Chamaecrista sect. Chamaecrista ser. Coriaceae (Leguminosae)A new circumscription of Chamaecrista sect. Chamaecrista ser. Coriaceae is presented based on the results of molecular and morphological analyses. The series is monophyletic upon exclusion of three species that were included within it by Irwin and Barneby. Morphological variation within the series is discussed. Characters previously neglected, such as...
