Validation of Prunus hainanensis (Rosaceae)

The name Prunushainanensis (G. A. Fu & Y. S. Lin) W. C. Chen is invalid because only the basionym was cited and without reference. According to the Art. 32.4 of ICBN, Prunus hainanensis (G. A. Fu et Y. S. Lin) H. Yu, N. H. Xia & H. G. Ye is the correct name. This new combination is proposed herein.
