As a complement to morphological research on the genus Isatis (Brassicaceae), an anatomical study was conducted on the fruit, leaf and stem of 18 species and four subspecies of this genus, as well as two species belonging to the genusPachypterygium. Inclusion of the members of the later genus in the study was to clarify the evidences that supported their affinity to the genus Isatis. As a resul...
