Duke 7523 (HOLOTYPE: MO; ISOTYPE: SEL barcode #001171). Syn. nov. Distribution. — Panamá, Colombia, and Ecuador, 0–1250 m. Discussion. — Type collections of Mandevilla sagittarii and M. dodsonii exhibit no noteworthy differences (Morales, 2011). Gentry (1981) cited M. dodsonii being related to M.hirsuta, differing by its corolla tube shape, but no relationship or inference with M. sagittarii was made. Some gatherings identified as M. dodsonii reported white or cream flowers instead of the yellow corolla typically found in M. sagittarii. However, the same variation is found in some other species of the exothostemon group (e.g, M. hirsuta).
