A mosaic virus of cowpea from Puerto Rico was found to be closely related serologically to cowpea mosaic viruses from Arkansas and Trinidad. This was demonstrated both by gel-diffusion and tube precipitin tests with partially purified preparations of the virus. The passive hemagglutination test again proved to be a highly sensitive method for detection of plant virus antigens. The virus content of directly inoculated leaves was proven serologically to be higher than the virus content of systemically infected leaves.
