Dr. Forfter in the South Sea iflands. In the other parts
of the world there has as yet been no fpecies difcovered.
Three fpecies only are found on the continent of America,
and the reft in the Caribbean iflands: they feem to
prefer mountainous fituations.
The genera moft allied to Cinchona are Manettia, Ron-
deletia, Macrocnemum, Bellonia, Portlandia, and fome
others ; and thefe feem to connect the laft divifion of the
■ Stellatas of Linnaeus, fuch as CofFea, Ixora, Pavetta, with
the family of Contortae, to which Cinchona, as to the
fruit, is nearly related; but it differs in having the
fruit below the calyx, and in the divifions of the co-
rol not being contorted into a fpiral before their expan-
fion.
The fpecies o f this genus are as follows:
I. Cinchona officinalis. This is the fpecies from which
is taken the genuine Peruvian Bark, and is that which
was firft difcovered: it is the fpecies which has given the
charadter of the genus, and is confequently that which
Linnaeus mentions in the old editions of his Syftema
Naturae, and in the 6th edition of his Genera Planta-
rum.
2. Cinchona pubefcens. So named from the pubefcent
appearance on the backs of the leaves: its native place the
fame as the foregoing. From the fhort and incomplete
defcription
defcription given by Condamine of a fpecies o f Cinchona
growing on the fummits of mountains, and of a whitifh
appearance, it fhould feem to be this.
3- C. macrocarpa. So named from the fuperior fize of
the fruit in comparifon to that of the others. This is the
fpecies difcovered by Mutis in large wqods in Santa Fe in
America: it is undoubtedly this fpecies which Linnseus
defcribes in the twelfth edition of the Syftema Nature,
On comparing Linnaeus’s defcription with that of Condamine,
and the figure given by him of C. officinalis, it is
evident that it by no means agrees with it; but on the contrary
it perfectly accords with my own of the C. macrocarpa
: and of this I am the more convinced, as Mutis never
fent fpecimens into Europe of the C. officinalis, it being
never found at Santa F e ; and daftly, that the fpecimen
preferved in the Linnasan collection is C. macrocarpa, and
not officinalis : its bark is white, and rather more bitter
than that of the officinalis. ? Some years ago a quantity
of it was imported to Madrid, and was tried by feveral
phyficians, who all agreed in declaring it equal to the
Peruvian.
4- C. Caribaea. Defcribed in the Philofophical Tranfac-
tions by a Mr. Wright.
5. C. floribunda, or Quinquina Piton of Monf. Badier.
The bark of thefe two fpecies is found of equal efficacy in
inter
