Hunst, Graduate Assistant, Department of Plant Pathology and Physiology, Virginia Polytechnic Institute and State University, Blacksburg 24061. Sue A. Tolin, Associate Professor, Department of Plant Pathology and Physiology, Virginia Polytechnic Institute and State University, Blacksburg 24061. Plant Dis. 66:955-958. Accepted for publication 8 May 1982. Copyright 1982 American Phytopathological Society. DOI: 10.1094/PD-66-955.

A potyvirus was isolated from Tahitian bridal veil (Gibasis geniculata) plants exhibiting severe stunting and leaf distortion. Infected cells contained laminated aggregates and crystalline inclusions. The virus reacted strongly with bean yellow mosaic virus and clover yellow vein virus antisera but differed in host range from reported bean yellow mosaic or clover yellow vein virus strains. The bridal veil virus isolate has been designated BYMV-BV.
