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 lacinie. 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 sete of 
the anthere. show an intimate affinity between Mutisia and 
Bichenia, before described.
