Mandevilla sagittarii Woodson, Ann. Missouri Bot. Gard. 19:72. 1932. TYPE: COLOMBIA. Chocó : entre La Oveja y Quidbó, 1–2 Apr 1931 (fl,fr), W . Archer 1714 (HOLOTYPE: US barcode #00112070; ISOTYPE: COL) .

Mandevilla dodsonii A.H. Gentry, Ann. Missouri Bot. Gard. 68:117–118. 1981. TYPE: ECUADOR. Los RÍos-Pichincha: fila en El Centinela, Montañas de Ila , camino de Patricia Pilar a 24 de Mayo, 600 m, 6 Feb 1979 (fl), C. Dodson, A. Gentry & J.A. 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 ).

barcodes #00646619,#P00646620,#P00646621]).

Distribution. — Endemic to Colombia, at (900) 1200–2200 m.

Discussion. — Based on Holm-Nielsen et al. 26516 (AAU), Potgieter and Zarucchi (1999) reported this species for Ecuador. However, this specimen must be identified as Mandevilla inexperata J.F. Morales , an endemic Ecuadorian species ( Morales 2007b).
