1. From the observation for several years on many varieties of tulips, authors are led to conclude that the types of dropper of tulip bulbs can be classified into the following four groups: mono-dropper type, di-dropper type, poly-dropper type, and branching dropper type (Fig. 1, 2, 3). 2. The formation of dropper was conspicuously different with the varieties. It was seldom to find the dropper in such varieties as Peach Blossom, Boldnage, Capri, etc., while in Kansas, Mozart, Eriford Keizerskroon and Inglescombe Yellow, they were apt to form the dropper. However it was difficult to find the correlation between the formation of dropper and the horticultural families, or earliness of flowering, and the formation of dropper was also not related to the content of soluble matter in bulbs or the number of root.
