The author observed an undescribed bacterial disease of pot marigold (Calendula officinalis L.) last year near Hokuoka and a study on its pathogene was undertaken. The disaese is very destructive in rainy period in autumn, specially in thick stand. When the plants are attacked the midribs of the leaves turn dark brown or black and large spots may appear on the blades resulting in the distortion of stem and leaves. On examination many bacteria were found in the diseased tissure and pure cultures were easily obtained. Its pathogenicity was proved by inoculations with spraying or rubbing. On agar plate the organism forms circular dirty white growth. And it is considered to be one hitherto undescribed. Therefore the name Bacterium Calendulae is porposed with following description.
