An Araliaceous plant from Subansiri District was found on a critical study to be Merrilliopanax Li, a genus founded on Dendropanax listeri King (in Journ. Asia. Soc. Bengal 67,2: 294,1898) from Assam. In a revision of the Araliaceae of China, Li (Sargentia 2: 62—65, 1942) showed that Dendropanax listeri King, with its paniculate inflorescence, 2-celled ovary, and 2 stylar arms did not fit within the generic characters of Dendropanax Decaisne & Planch, and erected the new genus Merrilliopanax. Apart from the type species M. listeri (King) Li, he described a new species, M. chinensis, from Yunnan, China. The Subansiri plant was found to be distinct from both the earlier described species and is now described as a new species.
