Abstract
Illicium nymphiiflorum Q. Lin & Y.M. Shui sp. nova (Schisandraceae) is described from China. It especially resembles I. viridiflorum from South Vietnam in being cauliflorous and in having similar greenish-white flowers and single-seriate stamens. It differs, e.g., in leaf shape (obovate vs. elliptic), apex of the innermost petals (acute vs. obtuse), arrangement of stamens (vertical vs. horizontal) and number of follicles (12–14 vs. 4–8). It also resembles I. stapfii, from which it differs in several floral characters. According to IUCN categories and criteria, I. nymphiiflorum is assessed as Critically Endangered (CR).
