Abstract

Euphorbia zhongiana (Euphorbiaceae), from Zhejiang Province, eastern China, is described and illustrated as a new species. It is morphologically similar to E. fauriei, however, differs in its winter green habit, whole plant being glabrous; cyathophylls 2, broadly ovate, yellow-greenish; involucre 2.5–3.0 × 2.5–3.0 mm; the surface of ovary usually smooth, rare sparsely microtuberous; styles connate at middle towards base; apex slightly 2–lobed; capsules smooth without tuberculate or conical verrucae, rare sparsely and inconspicuously rugose; seed coat with reticulate wrinkle.
