Baccharis caprariifolia DC. and B. erioclada DC., popularly known as “vassoura” [broom], occur in Southern Brazil and their external morphology is very similar. The leaf and stem pharmacobotanical characters were investigated by employing the usual light and scanning electron microscopy, as a means of differentiating the taxa. Although the species studied have a similar morphological characterization, a few anatomical characteristics can be considered diagnostic are as follows: the occurrence of stomata in the leaves and non-glandular trichome types.

Baccharis bre-vifolia DC., B. microdonta DC., B. pauciflosculosa DC., and B. trilobata A.S. Oliveira & Marchiori, which are popularly known in Brazil as " vassouras " (" broom "), are all found in Southern Brazil. The anatomical features of the leaf and stem were investigated by employing the usual light and scanning electron microtechniques, as a means of differentiating the taxa. The following anatomical characteristics can be considered to be diagnostic: the occurrence and type of stomata, midrib, stem and crystal shapes, and the presence of the petiole.
