[74] As early as 1790 the calisaya bark was highly prized in Madrid.
[75] The valuable species found in Bolivia and Southern Peru. Dr. Weddell derives the name from the Quichua words colli (red) and saya (form); Poeppig from colla (a remedy) and salla (rocky ground); Van Tschudi from collisara (reddish maize). Dr. Laefdael, the Judge of Caravaya, told me it came from ccali (strong) and sayay (become, or be thou). Calisaya is the name of a family of Indian Caciques in Caravaya, one of whom acted an important part in the revolt of 1780-1. The plant may have been called after him.
[76] The bark of C. Calisaya, known as "yellow bark" in commerce, was at first erroneously believed to come from C. cordifolia, because Mutis had called the bark from that species cascarilla amarilla, or "yellow bark." See p. 28.
