Amaioua longipedicellata (Rubiaceae, Gardenieae), a new species from the Brazilian Atlantic coast

Abstract : Background – Ongoing studies of Brazilian Rubiaceae revealed an undescribed species of Amaioua endemic to Atlantic Forest (Restinga and Semideciduous forest) of the state of Bahia, which is here described and illustrated, and its morphological characters are discussed and compared with those of similar species. Methods – This study is based on examinations of herbarium specimens, samples preserved in 60% ethanol, field observations, and digital images. Herbarium specimens of the CAY, CEPEC, HBR, IBGE, K, MBM, NY, RB, U, UB, UFG, and US herbaria were directly studied. Additional images of herbarium specimens were studied online. Results – Amaioua longipedicellata Delprete & J.G.Jardim is here described, illustrated and compared with the two most similar species, i.e., A. glomerulata (Lam. ex Poir.) Delprete & C.H.Perss. and A. intermedia Mart. A table comparing the morphological characters of these three species, and an appendix with selected specimens studied of A. glomerulata and A. intermedia are included.
