In 1923 five tubers and some seeds of Dahlia variabilis were obtained from Professor WEEVERS, from his garden in Ouddorp (Zeeland), the flower colour of which, according to his gardener, changed from red to white. The investigation begun with these was interrupted several times by circumstances for a shorter or longer period. The cultivation was, however, kept up, at any rate partially, by taking up the tubers every autumn, storing them in a frostproof house, and planting them in the spring. In the meantime several detailed studies on Dahlia variabilis (1-4, 6) by LAWRENCE and LAWRENCE with ROSE SCOTT--MONCRIEFF have appeared. We have, however, thought fit to publish the investigation as it does not refer to the genetic analysis of the colour factors, but confines itself to the loss of colour. The plants obtained in the following years from the five tubers and by vegetative propagation all show a great variation in the flower colour. All these plants will in the following invariably be referred to as W. The ray florets of some of the capitula are all vermilion-coloured, with a magnificent gloss, those of others are all white, whilst in the same flower both vermilion and white ray florets occur. The white, however, is not a pure white; it will therefore be indicated below by white. In most cases the white ray florets have a vermilion-
