Abstract


Stillingia (Euphorbiaceae) contains ca. 30 species from Latin America, the southern United States, and various islands in the tropical Pacific and in the Indian Ocean. We report here for the first time the occurrence of a member of the genus in China, Stillingia lineata subsp. pacifica. The distribution of the genus in China is apparently narrow, known only from Pingzhou and Wanzhou Islands of the Wanshan Archipelago in the South China Sea, which is close to the Pearl River estuary. This study updates our knowledge on the geographic distribution of the genus, and provides new palynological data as well.
