A viroid was detected from coleus (Coleus blumei Benth.) in Japan, which was 1 nucleotide larger (249nt) than coleus blumei viroid 1 (CbVd1) and coleus yellow viroid (CYVd), indicating that the viroid was an isolate of CbVd1. Four species of plants in Labiatae (Mentha spicata, Mentha arvensis var. piperascens, Ocimum basilicum and Melissa officinalis), in addition to coleus, were first found to be infected with the CbVd1 without showing any detectable disease symptoms.
