Abstract
Perrottetia taronensis from the Dulong Jiang valley in northwestern Yunnan Province, China and the Babulongtan mountain range in northern Kachin State, Myanmar is here described as a new species of the Dipentodontaceae. It is the third species of the genus to be recognized for China and the first to be reported for Myanmar. It is similar to P. alpestris s.s. but differs by characters of its leaf margins, inflorescences, and fruit. The three subspecies of P. alpestris recognized by Hou in “Flora Malesiana” are here recognized as three distinct species, i.e., P. alpestris, P. moluccana, and P. philippinensis on the basis of differences in diagnostic characters and distribution. The report in the “Flora of China” of the Taiwan species P. arisanensis from Yunnan is determined to be incorrect due to misidentification of two specimens at KUN.Keywords
