Recent studies using molecular data showed that the species traditionally treated as Viguiera Kunth in South America should be transferred to Aldama La Llave. After carrying out a taxonomic study of the 35 Brazilian species of Aldama, we propose three new combinations for binomials and two for varieties, plus a new variety, 20 new synonyms and 25 lectotypifications.
