Brome mosaic virus (BMV) was isolated from Commelina communis, C. diffusa, and five Gramineae species growing in a lawn. Three isolates, designated BMV-1, BMV-2, and BMV-3, were readily distinguished by their reaction in Datura stramonium. The isolates were serologically identical to each other and to the type isolate. The chrysomelid beetle Lema sexpunctata transmitted BMV-1 to C. communis.
