Abstract: The dividing line of geographic distribution and morphological differences between Pinus henryi Mast. and Pinus tabulaeformis Carr. were studied by means of numerical analysis. Data were taken from 24 morphological trails of cones, seeds and needles in natural stands, which included the entire range of Pinus henryi Mast. and the southern part of the range of Pinus tabulaeformis Carr. The results show that the morphological differences between Pinus henryi Mast. and Pinus tabulaeformis Carr. are highly significant. It was confirmed that Pinus henryi Mast. and Pinus tabulaeformis Carr. Are indeed two separate species, and the dividing line of geographic distribution between them is located in the Mi-Cang Mountain to the Da-Ba Mountain.
