Abstract
Cytological characters of ten taxa of the genus Lycoris were investigated to illustrate their chromosomal evolution. The fusion theory was more appropriate than the fission theory. From the viewpoint of the fusion theory L. sanguinea group, diploids with R-shaped chromosomes was the most primitive and they might have diverged into two directions, the diploids with V+R shaped chromosomes and the triped with V+R shaped chromosomes via triploids with only R-shaped chromosomes.
