Abstract:

Based on the morphological and anatomical characteristics of vegetative or-

gans,as well as the ecology and geography, Zhao Guang-yi et al. have reported

the occurrence of siberian pine(Pinus sibirica) in the Da Hinggan Mountains

continuously since 1981, that arouses disputing, The pine cones of the disputing

pine were collected in the Mangui Forestry Bureau in the Da Hinggan Mountains,

Northeast China, in autumn of 1989. By comparing it with those of Pinus sibirica

and P. koraiensis it is proved that the disputing pine in the Da Hinggan Mountains

is P. sibirica, but not P. koraiensis. And the 30-year old wrong name of “Mohe

Korean Pine” has been corrected. A map showing the distribution of the P.

koraiensis and P. sibirica in the DaHinggan Mountains and its adjacent regions

was drawn according to the 10-year investigation.

Key words: Da Hinggan Mountains, P. sibirica, New distribution
