SUMMARY A hitherto unrecorded disease of Hedysarum coronarium L. caused by Verticillium dahliae Kleb. is described. The isolate had a marked requirement for biotin, a characteristic it retained even when reisolated from different types of inoculated host plants. Although pathogenicity was readily established in preliminary pot experiments, difficulties were encountered in later years in inducing infection. The most successful method of inoculation was by dipping the roots into a spore suspension of the isolate in water. Variations in a range of soil conditions appeared to have no effect upon the incidence of disease. The isolate induced wilt in garden pea, sweet pea, and sainfoin, caused dark‐brown discoloration of the vascular tissue of apparently healthy broad bean, runner bean, lupin and Brussels sprouts, but had no apparent effect upon lucerne, potato, antirrhinum, chrysanthemum and tomato.
