Abstract: Two new species of Araliaceae from China are described based on material examined while preparing a treatment of the family for the Flora of China. Brassaiopsis pseudoficifolia Lowry & C. B. Shang, primarily found in Yunnan with a single collection known from adjacent Guangxi, most closely resembles B. ficifolia Dunn, but differs in having more numerously lobed leaves, more umbels per inflorescence, and prickles on the inflorescence axes and the stems. Schefflera zhuana Lowry & C. B. Shang, restricted to Mêdog County in southeastern Xizang, resembles S. leucantha R. Vig., but is distinguished by its ovaries with more carpels, an evident calyx forming a rim, a flat to depressed nectar disc, and thin leaf texture. Three previously recognized species (Brassaiopsis gaussenii Bui, Schefflera tenuis H. L. Li, and S. glomerulata H. L. Li) are formally placed in synonymy under currently recognized taxa.

Key words: Brassaiopsis, Schefflera, Brassaiopsis pseudoficifolia Lowry & C. B. Shang, Schefflera zhuana Lowry & C. B. Shang, Araliaceae, new species, new synonymy, China.
