Arthur: Uredinales of Porto Rico 
229 
Mona Island, although a specially thorough phanerogamic survey 
of the island has been made, the scanty material submitted by 
Dr. Stevens was gone over by Dr. Britton and Mr. Nash of the 
New York Botanical Garden, and again reviewed by Prof. Hitch- 
cock. Prof. Hitchcock writes, Feb. i8, 1915: “I have reex- 
amined it, and from the specimen itself I am inclined to think 
it may be Cenchrus viridis, but from the evidence which you 
present and the fragmentary condition of the specimen I think 
it best to let it stand as Cenchrus echinatus. The two species are 
closely allied, and one could not state with certainty from the 
fragmentary material that the specimen might not be a small 
fruited form of Cenchrus echinatus.” 
The species has also been found in Cuba and in Bahamas on 
C. echinatus, by E. W. D. Holway.
