The first record of the species for the West Indies. The two 

 collections show an abundance of uredinia, the spores of which 

 measure slightly smaller than do the urediniospores on Evolvulus 

 pilosus from the central United States. The difference is un- 

 doubtedly due to the influence of the host, E. pilosus being a 

 strong, thick-leaved plant, while E. nummularius is a delicate thin- 

 leaved plant with slender wiry stems. The species heretofore has 

 been known only from Kansas to the Mexican border in the 

 United States. The specific name of the rust was given under 

 a misapprehension regarding the identity of the type collection.
