SUMMARY The term antithetic is suggested for viruses which are usually associated and which are physiologically antagonistic. Tulip breaking results from the interaction of Tulip Virus I which inhibits flower and leaf colour and Tulip Virus II which adds flower colour but has no visible effect on chlorophyll distribution. The established commercial broken tulips contain physiologically balanced mixtures of these two viruses.
