For many years have been researching the conservation biology，horticiultural science and characteristics of Rhododendron plants in South west China both in the literature and in the field. Even today, this complex group of plants is poorly understood, Needed are systematic DNA research with carefully chosen samples, other cytological and chemical research (e.g., flavonoids, etc.), more ploidy and hybridization research, and more field research (distribution, habitat, population analyses, pollination, etc.).
