Bpecies of Goffea, and as these species are shown to be parasitic on 
several other rubiaceous plants belonging to different genera, which 
have an extended geographical range, their distribution should 
be carefully studied by those interested in the culture of coffee. 
The establishment of a coffee plantation in a ■ I istrict where those 
species of Hemileia capable of infecting coffee are present on 
indigenous vegetation, would be tempting providence, and i>r< >ba I »] v 
result in disaster.
