摘　　要：描述了产自云南的球兰属一新种四花球兰(Hoya tetrantha J.F.Zhang,Y.H.Tong&N.H.Xia)。该种为附生灌木,具有一年生的顶生花序和小型叶片,而与产自缅甸的狄克森球兰(H.dickasoniana P.T.Li)相似,但该种叶片卵形至阔卵形,先端锐尖,具短尖头,花序通常具4朵花,萼片线形且较长而与后者区别。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.
