Abstract:
The taxonomic identity of Chrysocoma linearis, C. monantha, and C. opposita (Asteraceae), described in Vellozo's Florae Fluminensis, is reassessed. Based on the analysis of the protologues, original illustrations, and additional taxonomic evidence, we propose two new combinations in Chrysolaena and one in Piptocarpha. Field expeditions conducted between 2021 and 2022 in the municipality of Cunha, state of São Paulo, the locality most likely associated with these names, provided additional material. We designate three lectotypes and three epitypes, propose new synonymies, and provide distribution maps, illustrations, and taxonomic comments for the species involved.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
