Summary. The bulb rot disease, or ring disease, of Narcissus is due to the attack of an eelworm, Tylenchus devastatrix. These eelworms are of constant occurrence in the diseased bulbs, and the disease can be produced by infecting healthy plants with the eelworm. A description is given of the symptoms and course of the disease as it appears in nature, and certain precautionary measures are suggested. I have great pleasure in expressing my thanks to Mr J. W. Barr (Messrs Barr and Sons), Mr Hales (Chelsea Physic Gardens), Mr Leake (The Floral Farms, Wisbech), Mr Pearson (Messrs J. E. Pearson and Sons), and Mr J. Walker (Walker Bros.) without whose cordial cooperation and generous help the work could not have been carried out. I am also indebted to Mr J. C. Fryer for help and suggestions with regard to treatment. I should also like to take this opportunity of thanking both Professor V. H. Blackman and Professor J. B. Farmer for their stimulating and helpful criticism.
