eontains Cinchonia alone; C. oblongifolia contains both 
Cinchonia and Quina; and C. cordifolia Quina alone. 
Great uncertainty prevails with regard to the exact species 
from which the various kinds of Peruvian bark are procur- 
ed; and other genera besides Cinchona are bitter and fe~ 
Wrifuge. C. Condaminea, C. ovalifolia, C. micrantha, C. 
nitida, C. lucumefolia, C. lanceolata, C. rotundifolia, C. 
glandulifera, C. hirsuta, C. magnifolia, C. purpurea, furnish 
good bark, and much of what is brought to this country, be- 
sides the species mentioned above. Exostema caribeum and 
E. floribundum are febrifuge, and called false Cinchonas, 
but do not contain either Quina or Cinchonia. Several 
others furnish a kind of false bark. A bitter and very as-_ 
tringent matter, called Gambeer, is obtained from the leaves 
of the Nauclea Gambir (Uncaria G.); this is said to be the 
Kino of druggists, while others say that Catechu is got 
from it. 
Ipecacuan root is obtained from Cephelis Ipecacuanha 
[Giilicvoca Z). It contains an active principle, of a peculiar 
nature, called Emetine. Psychotria emetica furnishes the 
root: called Black or Striated Ipecacuan. The roots of 
; ia scabra, R. emetica, Spermacoce poaia, S. Fer- 
ruginea, and Manettia cordifolia, are also emetic. Chiococea 
anguifuga and C. densifolia are drastic purgatives, and much 
used in Brazil.
