Malpighia emarginata is a tropical fruit-bearing shrub or small tree in the family Malpighiaceae. Common names include acerola cherry, Brazilian Portuguese, European Portuguese, Barbados cherry, West Indian cherry, wild crepe myrtle and seriz.
Acerola is an evergreen shrub or small tree with spreading branches on a short trunk. It is usually 2–3 m (6.6–9.8 ft) tall, but sometimes reaches 6 m (20 ft) in height. The leaves are simple ovate-lanceolate, 2–8 cm (0.79–3.15 in) long, 1–4 cm (0.39–1.57 in), and are attached to short petioles. They are opposite, ovate to elliptic-lanceolate, and have entire or undulating margins with small hairs, which can irritate skin. The fruit of acerola is edible and widely consumed in the species' native area, and is cultivated elsewhere for its high vitamin C content.
