Abstract:Hoya tetrantha J. F. Zhang, Y. H. Tong & N. H. Xia (Apocynaceae, Asclepiadoideae), a new species from Yunnan Province, China, is described and illustrated. This species is similar to H. dickasoniana P. T. Li in being an epiphytic shrub with annual terminal inflorescences and small leaves, but can be different from the latter by its ovate to broadly ovate leaf blades with an acute and mucronate apex, usually 4-flowered inflorescences and flowers with longer linear sepals.
