S ummary1 The production by the cells of Protea cynaroídes of a bacteriolysin against the organism which produces a leaf‐spot disease, suggested in a former paper, has not been confirmed. 2 The bacteria enter the leaf by way of the stomata; the local lesions produced are prevented from spreading by the development of wound cork. 3 The causal organism succumbs very readily to the desiccation to which it is subjected owing to the cells which it attacks being cut off by the wound cork from their water supply.
