2D83EB6C6941588F80ADBE885B40586F.taxon	diagnosis	Diagnosis Adenocalymma darwinii resembles A. hirtum (Mart. ex DC.) Bureau & K. Schum. and A. salmoneum J. C. Gomes. It shares with A. hirtum the hirsute indumentum on the branches, petioles, petiolules, major veins of the leaflets, inflorescence axis, bracts, bracteoles, and calyx. However, it can be differentiated by the presence of slightly gibbous corolla with narrow aperture, and exserted anthers and stigma. It shares with A. salmoneum the slightly gibbous corolla with narrow aperture, cupular trichomes at the apex of the corolla, and exserted anthers and stigma. However, it can be differentiated by the scandent shrub-like habit (vs lianescent), the hirsute indumentum on the branches, petioles, petiolules, major veins of the leaflets, inflorescence axis, bracts, bracteoles, and calyx (vs glabrous), linear bracts (vs elliptic), yellow corolla (vs orange), and the anthers and stigma exserted or at the corolla mouth (vs included in the corolla tube).	en	Fonseca, Luiz Henrique M., da Silva Ribeiro, Ricardo (2026): Taxonomic novelties in Adenocalymma (Bignonieae, Bignoniaceae) endemic to the Atlantic Forest.

2D83EB6C6941588F80ADBE885B40586F.taxon	etymology	Etymology We are describing Adenocalymma darwinii to celebrate the great British naturalist, Dr Charles Darwin. Known as one of the fathers of the theory of evolution by natural selection and the author of the book On the Origin of Species. His discoveries and insights inaugurated a new perspective on how biodiversity is perceived and understood. This tribute is also a reminder of the importance of his ideas and how influential they remain.	en	Fonseca, Luiz Henrique M., da Silva Ribeiro, Ricardo (2026): Taxonomic novelties in Adenocalymma (Bignonieae, Bignoniaceae) endemic to the Atlantic Forest.
