Epidemics of the obligate biotrophic fungus Puccinia lagenophorae might be used to control populations of the annual plant, groundsel, Senecio vulgaris. The study of ecological interactions both at the individual plant and at the population level between Senecio vulgaris (common groundsel) and the rust fungus Puccinia lagenophora has been a major focus of our research during the past 15 years. The first true leaves of seedlings have shallow teeth, may be purple on the underside, and are attached to the stem with a short petiole. Variously circumscribed taxonomically, the genus Senecio is one of the largest genera of flowering plants.
