Myrciaria dubia

Myrciaria dubia, commonly known as camu camu, camucamu, cacari, or camocamo, is a small bushy riverside tree from the Amazon rainforest in Peru and Brazil, which grows to a height of 3–5 m (9.8–16.4 ft) and bears a red/purple cherry-like fruit. It is a close relative of the jabuticaba (Myrciaria cauliflora) and the guavaberry or rumberry (Myrciaria floribunda). As much as 2-3% 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)m in length and 1–2 cm (0.39–0.79 in) wide. The current range of camu camu consists of the Amazonian lowlands of Colombia, Ecuador, Peru, Bolivia, and Brazil. Its distribution extends from the center of Pará state, Brazil, along the mid and upper Amazon River to the eastern part of Peru; in the north, it appears in the Casiquiare and the upper and middle Orinoco River. In Brazil, it is found in Rondônia along the Maçangana and Urupa Rivers and in Amazonas, in the municipalities of Manaus and Manacapuru and along the Javarí, Madeira, and Negro Rivers. Long used by native peoples, wild camu camu fruit is harvested directly into canoes. The fruit has only recently come into large-scale cultivation and sale to the world market, with Japan being the major buyer. The tree is relatively easy to cultivate within certain growing conditions. It survives best in hot, damp, tropical climates, but will grow in the subtropics, surviving temperatures down to just above freezing. It requires copious water. Fair trade is present in low-land production from the Association of Camu Camu Producers of the Peruvian Amazon.
