cinchona -

Cinchona is a genus of about 25 species of Rubiaceae originating from tropical South America. Members of this genus are large shrubs or perennial green trees that grow to a height of 5-15 meters.

The bark of the tree is the source of many different types of alkaloids, the best known being quinine, an antipyretic compound (antidote for fever) primarily used in the treatment of malaria. Of the many quinine producers, only C. officinalis and C. pubescens (syn C. succirubra) are cultivated in plantations. C. officinalis subsp. ledgeriana which is used as rootstock. Both of these types are known in trade as quinine plants.
