regard to the variability of these rusts is the comparative constancy, 
in spite of wide distribution, of the several rusts upon the related 
genera Epilobium and Chamaenerion. This fact, with others, it 
seems to the writer, indicates that the variability of the rusts upon 
the Onagraceae, as similarly noted by Dr. Arthur with the rusts upon 
the Rosaceae, reflects the variability of the hosts themselves. Indeed, 
the evolution of these hosts and their rusts would appear to present 
many parallelisms.
