SUMMARY Clusters of isometric virus‐like particles c. 22 nm in diameter, embedded in amorphous electron‐dense material, were found in the phloem tissue of Anthriscus cerefolium (chervil) plants infected with the semi‐persistent aphid‐borne virus, anthriscus yellows (AYV). The particles resembled those seen previously in thin sections of AYV‐transmitting aphids (Cavariella aegopodii). The particles were found only in the central vascular bundle of the petiole and its continuation in the leaf midrib. They were also found in extracts made by grinding petiole and midrib tissue in 10 % sucrose using Carborundum. These results confirm earlier studies which suggest that AYV is confined to deeper‐lying tissues.
