Resumen:
The genus Stenocephalum (Vernonieae, Asteraceae) includes six South American species that have cylindrical heads, 4-11 forets by capitula, cymose inforescences 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 inforescence. Consequently, in this paper S. monticola is resurrected from the synonymy of S. apiculatum, re-described and illustrated.
