Tsuga longibracteata is one of the rare gymnosperms endemic to China. With the changes in environmentand ecosystems,the total number of individuals has decreased rapidly and it is considered an endangeredplant on the brink of extinction. In this paper, a broad literature has been reviewed concerning its habit,morphology, structure,karyotypes , growth traits and wood properties,geographic distribution,ecologicaland community characteristics. Although controversy still remains about its systematic position,the authors support the conclusion that the plant should be validated as a genus,Nothotsuga,in Pinaceae basedon the features reviewed. Consequently,the reasons for making the plants to the endangered state havebeen analysed and the effective measures have been put forward to conserve the rare species.
