Abstract
More than twenty years ago the senior author found Camellia japónica trees in Opatija (Croatia) with colour breaking on the petals and symptoms of virus infection on the leaves. At that time it was known that this viral disease was transmissible by grafting but not mechanically.
During recent investigation on Camellia from Opatija we found viral symptoms again on leaves in the form of variegation, ringspots and necrotic rings, and on red petals in the form white spots. We performed electron microscopic investigations of infected tissues and in the young petals of Camellia we found bacilliform particles with dimensions of 30X150 nm. This virus had the same form and similar dimensions as the virus described by Hiruki (1985). In the virus, a helicoidal structure was observed which stretched all along the elongated particle. This virus was named Camellia infectious variegation virus (CIW) by Hiruki.
