Show Wild Cinchona Trees Found in Costa Rica CHICAGO. Cinchona trees, the source of quinine, have been found growing wild in the Central Cen-tral American republic of Costa Rica. Specimens of this unique discovery discov-ery have been received at the Field Museum of Natural history here. Wild cinchona trees have not hitherto hith-erto been known outside their ancient an-cient home in the Andean highlands of South America. The world's supply of quinine is at present derived from plantation trees in the East Indies. The old South American cinchona forests, mercilessly exploited, were practically practi-cally wiped out many years ago. |
