Cinchona pubescens

Cinchona pubescens, also known as Red cinchona and quina ((Spanish) Cascarilla, cinchona; (Portuguese) Quina-do-Amazonas, quineira), is native to Central and South America. It is known as a medicinal plant for its bark's high quinine content- and has similar uses to Cinchona officinalis in the production of quinine, most famously used for treatment of malaria.[1]


Cinchona pubescens has the widest distribution of all Cinchona species, with the native range spanning Costa Rica, Panama, Venezuela, Colombia, Ecuador, Peru, and Bolivia.[2] In Ecuador it is distributed within an altitude from 300–3,900 metres (980–12,800 ft).

Invasive species[edit]

It has become an invasive species where planted outside of its native range, especially on tropical climate islands.[3]

In the Galapagos it has become a dominant species in the formerly shrub dominated Miconia and Fern-Sedge zones [4] on Santa Cruz Island.[5] It has been subject to control in the Galapagos National Park [6] to reduce its impacts using a variety of methods.[7] However, controlling it over its total range on Santa Cruz island would cost several million US dollars according to research done through the Charles Darwin Foundation.[8]

It is also invasive in Hawaii, on Maui and the Big Island [9]
