Mandevilla sanderi, the Brazilian jasmine, is a vine belonging to the genus Mandevilla. Grown as an ornamental plant, the species is endemic to the State of Rio de Janeiro in Brazil.
Mandevilla sanderi is a shrub with a naturally bushy habit, 2–3 meters high, or 4.5 meters (15 feet) if the climate is warm. It is able to develop long, woody stems based on lignin and climbs by twining around some support. This twining growth is characterized by long internodes, small leaves and a stem rarely carrying flowers. The plant contains a white latex, which is viscous, toxic, and can be irritating. In addition to fine roots, it has large tuberous roots that contain starch and a reserve of water, allowing it to withstand drought. The evergreen, petiolate, thick, leathery, dark green leaves are opposite, and grow to 6 cm (2.5 in) long. The blade is ovate-elliptical, 5–6 cm long, with a glossy upper surface and a thick epidermis. The apex is shortly acuminate.
