New combinations or new names for two sections ， 28 species and the infraspecific taxa taxa are proposed under the conserved generic name Ch η santhemum L. The genus is cir- cumscribed cumscribed here almost as identical with Dendranthema of Kitamura (1 978) including Ajα nia ，Arctanthemum ， Dendranthema and Ph αeostigm αin the sense of Bremer and Humphries Humphries (1993). A list of the Japanese species of Chrysanthemum is provided.

Key words: Asia ，Chrysanthemum ，Dendranthema ，new combinations ，new names.

The generic name Chrysanthemum L. is of Dendranthema as (A. pacifica conserved conserved with a conserved type C. indicum (N akai) K. Bremer & Humphries and A. L. L.
