    Description: Two new species of the genus Lessingianthus (Vernonieae, Asteraceae) from Brazil and Paraguay are described and illustrated. Lessingianthus cipoensis is characterized by the presence of solitary heads disposed in short branches and ovate to elliptical leaves. It has a certain resemblance to L. vestitus, which has more branched inflorescences, with long branches, and lanceolate to obovate-lanceolate leaves. Lessingianthus paraguariensis is closely related to L. asteriflorus and L. mollissimus, but it can be distinguished by the broadly elliptical leaves and the large size of the outer phyllaries.

    Description: The genus Stenocephalum (Vernonieae, Asteraceae) includes six South American species that have cylindrical heads, 4–11 florets by capitula, cymose inflorescences and type ‘C’ pollen. Until now, Stenocephalum monticola has been considered as a synonym of S. apiculatum. However, the analysis of the type material and additional specimens indicate that it is a quite different species, which differs in leaf size, pubescence and capitula arrangement. Stenocephalum monticola has leaves of 9–20 mm long, leaf blades villous at the base and capitula agglomerate at the stems tips, while S. apiculatum presents leaves of 30–60 mm long, leaf blades basally glabrous and heads mostly solitary, arranged in a pseudo-spiciform inflorescence. Consequently, in this paper S. monticola is resurrected from the synonymy of S. apiculatum, re-described and illustrated.

    Description: The genus Stenocephalum (Vernonieae, Asteraceae) includes six South American species that have cylindrical heads, 4\xe2\x80\x9311 florets by capitula, cymose inflorescences and type \xe2\x80\x98C\xe2\x80\x99 pollen. Until now, Stenocephalum monticola has been considered as a synonym of S. apiculatum. However, the analysis of the type material and additional specimens indicate that it is a quite different species, which differs in leaf size, pubescence and capitula arrangement. Stenocephalum monticola has leaves of 9\xe2\x80\x9320 mm long, leaf blades villous at the base and capitula agglomerate at the stems tips, while S. apiculatum presents leaves of 30\xe2\x80\x9360 mm long, leaf blades basally glabrous and heads mostly solitary, arranged in a pseudo-spiciform inflorescence. Consequently, in this paper S. monticola is resurrected from the synonymy of S. apiculatum, re-described and illustrated.
