Brassaiopsis producta (Dunn) C.-B. Shang, a new record of Araliaceae from Vietnam

Brassaiopsis producta (Dunn) C.-B. Shang (Araliaceae) is herein reported to occur in Ha Giang, Lang Son and Son La provinces, Vietnam. The taxon was previously known only from China (Guangxi, Guizhou, and Yunnan provinces). It is similar to the widespread B. glomerulata in the prickly stems and palmately compound leaves, but is easily distinguished from the latter by B. producta's evergreen and subcoriaceous leaves and its 5- or rarely 4-locular ovaries.
