undivided stigma; after we have examined the relation and 
supposed similarity of mixture of Cinchona, Portlandia, Couta- 
rea, Cosmibuena, Pinkneya, Danais, Bonplandia, Cuspa, and the 
Acatamez tree, we pass to the definition of those species of Cin- 
_‘chona which have become an object of great importance in the 
practice of physic and in the intercourse of nations. Without 
the fundamental exposition of the specific characters, and with- 
out adjusting some part of the synonymy, every thing which I 
am going to state respecting the geographical diffusien of the 
Cinchone, and their pbysical relations, would remain indi- 
stinct and dubious, smce (as TP have mentioned above) a pecu- 
liar region has been destined for almost every species, and 
some botanists have, to the great detriment of science, given 
one and the same name to the most heterogeneous species. Thus, 
for instance, Cinchona longiflora, Mut. is “ona different from 
Ce longiflora, Lambert. It is true, they both oot 
eorolla, and Suileng to the Cinchonz which are ford of fda 
and possess fewer medicinal powers. But the first, from New 
Granada, has inclosed stamens, and is probably identical with 
C. grandiflora Flor. Peruv. Ow the other hand, the C. longt- 
flora, Lambert, from French Guiana, belongs to those species 
which have long projecting filaments and very short capsules, 
Cinchona Caribea, Jacq. is totally different from that Cinchona 
Caribea described in the Journal de Physique, Oct. Bic The 
diagnoses which I add are not borrowed from works alrea 
published, but arise — from my own obser vatiol a me PP
