Technical Abstract: <i>Ammi majus</i>, also known as false Queen Anne’s lace or bishop’s flower, is an annual in the Apiaceae. <i>A. majus</i> is native to the Mediterranean but it is cultivated in major growing areas including Holland, Israel, the UK, and the US and is frequently used in the floral trade to add a lacy look to bouquets. <i>A. majus</i> is frequently confused with roadside Queen Anne’s lace, <i>Daucus carota</i>, which is a common weed in the US. Virus-like symptoms including mosaic, generalized chlorosis, vein clearing, interveinal chlorosis, leaf deformities, and leaf rugosity were observed in two cut-flower production fields in south Florida in March 2005. Cylindrical inclusions typical of a potyvirus infection and testing with a commercially-available enzyme-linked immunosorbent assay for multiple potyvirus species indicated the presence of a potyvirus. An additional inclusion body in <i>A. majus</i> and symptoms on mechanically inoculated <i>Chenopodium quinoa</i> indicated that a second virus may also be present. There are no prior reports of a virus infecting <i>A. majus</i> in Florida. Elsewhere, Anthriscus latent virus, Caraway latent virus, <i>Celery mosaic virus</i>, Parsley green mottle virus, and Parsnip leafcurl virus have been reported.
