An isometric virus isolated from Passiflora edulis in Peru had typical properties of a nepovirus. It infected a wide range of dicotyledonous plants, inducing mainly chlorotic and / or necrotic spots and rings. In Chenopodium species, it caused apical necrosis. It was not transmitted by aphids. Its coat protein had a molecular weight of about 56,000. In the serological agar gel double-diffusion test, it could not be distinguished from the tobacco strain of tomato ringspot virus. Unlike the type strain of this virus, however, it did not infect tomato systemically.
