The authors' observations on the flower bud differentiation and its development in amaryllis bulbs are summarized as follows:1. Usually the growing point of amaryllis bulb changes into a flower bud after it has formed four leaves, then a new growing point starts from the bottom of the newest leaf. Therefore most bulbs have four leaves between every successive flower buds (72% of the observed cases), but in a few cases one to eleven leaves are counted between the flower buds.2. Ten stages are set up in the course of developmeant of flower bud, from the state of vegetative growing point to the pistil formation stage. (Fig. 2)3. While a flower cluster primordium is developing to complete flowers, the growing point usually differentiates eight new leaves and two new flower buds.
