Charles was horn in Angoulome, 

 4th September 1789, and died in Paris, 16th January, 1854. 

 He was a "Pharmacien de la le Classe de la Marine," and 

 professor of botany. He accompanied the present expedition 

 as pharmacien-botaniste. 



The official botanical publications of this expedition 

 already referred to are an important contribution to science, 

 while his other works include "M'moire sur les Cycadees " 

 (1821-5), "Notice sur les genre Adriana " (1825). Most of 

 his papers are, however, on physiology or morphology. 

 Biographical accounts of him will be found in (2), (3), (i).
