Habitat. — In the declivities and rugged portions of the 
mountains, at an altitude of 1500 to 1800 m., and in the 
woods of the hottest vallies of Bolivia and southern Peru, 
between 13° and 16° 30' S. L.,and 68° and 72° West Long, 
in the provinces of Bolivia, called Enquisivi, Yungas, Lare- 
caja and Caupolican, and in the Peruvian province Cara- 
baya. It flowers in April and May. 
The bark is commonly called indiscriminately by the 
Spaniards and Indians Cascarilla Colisaya, Calisaya or 
Culi say a. 
The varieties consist in the bark and leaves being more 
delicate, in the panicle being sub-diffused, and in the 
flowers being smaller, (vulg. Calisaya blanca.)
