Mandevilla riparia (Kunth) Woodson, Ann. Missouri Bot. Gard. 19:58. 1932.

Echites riparius Kunth , Nov. Gen. Sp. 3 214.1819. TYPE: COLOMBIA. Magdalena:Tenerife,rÍo Magdalena, May year unknown (fl), A. Humboldt & A.Bonpland 1711 (HOLOTYPE: P-HB barcode #00670891; ISOTYPES: B-W, P barcode #00646658).

Distribution. — Colombia (?) and Perú, at 2000–2900 m.

Discussion. — The type of Echites riparius was supposedly collected in Colombia in a low elevation area (less than 50 m), but all the known specimens have been collected in high elevations in Perú. Mandevilla riparia was cited by Potgieter & Zarucchi (1999), but the voucher specimen and other gatherings with the same name in Ecuadorian herbaria correspond to M.assimilis ( Morales 2005c) .
