Samples of commercially grown Impatiens holstii from several sources in Minnesota contained a carlavirus which serologically was closely related, if not identical with Helenium virus S described earlier in Germany. The two viruses have similar experimental host ranges and caused similar cytopathogenic effects. After mechanical transmission the Impatiens isolate produced less severe symptoms in Impatiens than the Helenium isolate. Only the latter isolate was transmitted by Myzus persicae in the non‐persistent manner.
