Metternichia. 



This genus was proposed by Dr. Mikan for a beautiful 

 shrub, with*large white flowers from the neighbourhood of 

 Rio de Janeiro, and by him dedicated to Prince Metternich, 

 the liberal patron of the many scientific expeditions that 

 have so greatly extended our knowledge of the Natural 

 History of Brazil. It comprises only a single species, ot 

 which a very good figure was published by Dr. Mikan in his 

 Delect. Flor. et Faun. Braz. 3, tab. 1, but as that work 

 is extremely scarce, and the details of the seeds not quite 

 perfect, I offer the results of my own observations.
