Camu camu

Myrciaria dubia, commonly known as camu-camu, caçari, araçá-d'água, or camocamo, is a species of plant in the family Myrtaceae. It is a small bushy riverside tree from the Amazon rainforest in Peru and Brazil, which grows to a height of 3–5 m and bears a red/purple cherry-like fruit. It is a close relative of the false jaboticaba (Myrciaria vexator) and the guavaberry or rumberry (Myrciaria floribunda). As much as 2 to 3% of the fresh fruit by weight is vitamin C. Camu-camu has small flowers with waxy white petals and a sweet-smelling aroma. It has bushy, feathery foliage. The evergreen, opposite leaves are lanceolate to elliptic. Individual leaves are 3–20 cm (1.2–7.9 in) in length and 1–2 cm (0.39–0.79 in) wide.
