This paper reviewed the distribution patterns, diversity hotspots, research status and protection of rare species related to chrysanthemum. The survival and protection status of Chrysanthemum, Ajania and other rare or endemic Asteraceae species in China was reported. Then, the research progress and proposed protection levels of a number of rare germplasm resources were put forward, mainly including C. rhombifolium, C. zhuozishanense, A. sericea, Opisthopappus taihangensis, Formania mekongensis, Leucomeris decora and Nouelia insignis. In addition, we systematically expounded the research progress of rare species protection from two aspects: habitats investigation and endangered mechanism research. Finally, from the perspectives of advanced monitoring technology system excavation and interdisciplinary analysis, the research methods and future prospects for the protection of chrysanthemum related wild germplasm resources were suggested.
