Yes, it is, but only for Shasta and Oxeye daisies. Other plants once called chrysanthemums are either still classified as Chrysanthemum or have been moved to other genera (Dendranthema, Arctanthemum, Rhodanthemum, etc.). If you browse by genus and look up Chrysanthemum, you'll find plants with lots of different genus names.
