Popis:	There are still controversies regarding differentiation between Baccharis species (sect. Caulopterae). In the present work, we compare three species: Baccharis articulata, Baccharis gaudichaudiana and Baccharis trimera, emphasising the importance of anatomy, polypeptide profiles and ultraviolet–visible spectrophotometry as taxonomic characters, utilizing multivariate analysis. Seventy-two populations of the three species were examined. The first two principal components of morphoanatomical data gathered relevant information to classify species (61% of the total variability), with the largest contribution from the stomata density variable (2.105). PCoorA based on protein analysis enabled separation of the species with the first two principal coordinates (67.20% of the total variability). Regarding spectrophotometrical data, the second and third principal components only separated B. trimera from the rest (22.7% of total variability).
