 Florida, called by him Mussmda bracteata. Michaux 

 established the genus, dedicated to General Pinckney, a 

 botanist, philosopher and statesman ; it is intermediate 

 betw^een Cinchona and Mussenda. Only one species is 

 known, found from Carolina to Louisiana, along the sea 

 coast, in cool, shady groves and swamps, on the banks 

 ol rivers, &c. It blossoms in June and Jiily, and is very 

 ornamental. The genus Cinchona, producing- the Peru- 

 vian bark, extends no further north than the West In- 

 dies ; this shrub appears to be the representative and 

 substitute of it on the noTth continent, by its near orga- 

 nization and qualities.

 ruvian barks ; the inner bark is bitter, and contains
