in the corolla, which are from 10 to 15 in the florets of the circum- 

 ference, and 10 in those of the disk. These vessels are generally 

 of the same thickness, and all originate from the base ; but in 

 the exterior lip of the centre florets, where they are eight in 

 number, the alternate ones are more slender, and disappear 

 before they reach the apex of the laciniae. The number of 

 vessels is uniform in the nine species here enumerated, and 

 there is every probability of its being general throughout the 

 rest of the genus. This character and the pubescent seta? of 

 the antherae show an intimate affinity between Mutisia and 

 Bichenia, before described.
