This dataset contains the digitized treatments in Plazi based on the original journal article Fonseca, Luiz Henrique M., da Silva Ribeiro, Ricardo (2026): Taxonomic novelties in Adenocalymma (Bignonieae, Bignoniaceae) endemic to the Atlantic Forest. Plant Ecology and Evolution 159 (1): 3-11, DOI: 10.5091/plecevo.172513
Abstract
Background and aims – During ongoing morphological studies of Adenocalymma, we realized that nomenclatural updates are necessary in the genus. Here, we propose a new circumscription of A. acutissimum and the description of the new species A. darwinii.
Material and methods – Morphological and phylogenetic evidence support the new circumscription of A. acutissimum, while the new species is recognized based on morphological grounds and compared to A hirtum and A. salmoneum.
Key results – We removed the taxa A. comosum, A. comosum var. lanceolatum, and A. nitidum as synonyms of A. acutissimum. We also presented a detailed description for A. darwinii sp. nov., an illustration, and information on its distribution, habitat, phenology, and extinction risk. A map showing the occurrence of both A. comosum and A. darwinii sp. nov. is shown.
Conclusion – These results emphasize once again the importance of taxonomic studies in the Brazilian Atlantic Forest and highlight conservation concerns for its flora.
