Cultivated on the Nilgiris and other hills of South India, at the plantations of 

 Rangbi and Poomong in Sikkim, on the hills east of Toungoo in Burma and in parts 

 of the Satpura Range in Central India. This species thrives at a lower elevation 

 than the others, but is comparatively poor in quinine, though rich in cinchonine and 

 cinchonidine. From this species is chiefly derived the "Cinchona Alkaloid," which is 

 now largely manufactured at the Government Plantation of Rangbi.
