for the C. glandulifera, Flor. Peruv.; but this latter differs 
corolla solummodo intus lanuginos’, tubo externe glaberrimo, 
foliis inferne villosis.* The inhabitants also enumerate the 
©. glundulifera, which is called (at Chicoplaya) Cascarilla ne- 
_grilla, among the less efficacious species of Cinchona. 
If any one species deserved exclusively the name C. offici- 
nalis, it would be the tree which produces the Cascarilla fina 
de Uritusinga, a bark which has always been held in Spain as 
the most efficacious in tertian agues, and which at present is ga- 
thered only for the Royal Apothecaries’ Hall, and is therefore ne- 
ver met with in trade by lawful channels. Notwithstanding these 
preferences, we have, for several reasons, preferred giving it a 
new name, not derived from its quality or medicinal’ powers. 
1°; Not one species, but all provided with hairy and woolly blos- 
soms, are Cinchon# of the shops, and no species deserves an ab- 
solute preference, since different species are to be applied accord- 
ing to the difference and form of the disease : for instance, in in- 
termittent fevers of long standing, the €. Condaminea and C. lan- 
cifolia, Mut. ; in diseases of the muscles or suppurating ulcers, 
the C. oblongifolia, Mut.; in the after treatment, to prevent 
relapses, the more mild C. cordifolia, Mut. 2°. In botanical 
writings, species of Cinchena totally distinct have been de- 
scribed by the name of C. officinalis. Had we bestowed the 
same name on the Cinchona of Uritusinga, it would have been 
confounded with the yellow @. cordifolia, Mut., the w rite 
(BF macrocarpa, Vahl, or even with the C. nitida, Ruiz, which at 
different periods have been called C- officinalis. — 
_ This latter point, equally important to the botanical synonymy 
and to the materia medica, merits a more circumstantial expla- 
nation. It is asked, What plant did Linnzus, in the 12th edition
