SUMMARY
A virus inducing vein clearing and a slight mottle of Malva parviflora was found at Campinas, Brazil. Samples prepared by the exsudate or dipping methods from diseased and healthy control plants were examined in the electronmicroscope.
Elongated virus particles with a normal length of 830 mμ and a diameter of 15 mμ were found in all preparations from diseased plants and not in those from control plants.
According to its particle morphology and other characteristics, the malva vein clearing virus represents a new group and the writers propose that it be included as group 11a between groups 11 and 12 of Brandes and Wetter's classification.
