186 DR. H. A. 'WEDDELL ON THE GEXERTC NAME CASCAKILLA. 



the second, the reason for which he did not adopt it as a generic 

 name, instead of creating a new one, being very probably the same 

 that led me to leave it equally aside for that of Cascarilla, namely 

 the confusion existing between it and Cosmibuena of Euiz and 

 Pavon. On reflection, however, such an error, even when coun- 

 tenanced by Pohl himself, cannot stand against fact ; and the fact 

 is that Buena (typified in -B. hexandra) and Cosmibuena of Buiz 

 . and Pavon are widely distinct, the lobes of the corolla, for in- 

 stance, being strictly valvate in the flower-bud of the first, while 

 in that of the second they are contorted, &c. 



According to law, then, the name of Buena niust supersede that 

 of Cascarilla ; and I propose, in consequence, that all the species 

 I have described under the head of Cascarilla shall be hencefor- 

 ward ranked under that of £uena, as in the subjoined list.
