Cathaya argyrophylla

Cathaya is a genus in the pine family, Pinaceae, with one known living species, Cathaya argyrophylla. In foliage and cone morphology, Cathaya has been considered a member of the subfamily Laricoideae, closely related to Pseudotsuga and Larix, but more recent genetic studies have suggested a closer relationship to Pinus and Picea in the subfamily Pinoideae. A second species, C. nanchuanensis, is now treated as a synonym, as it does not differ from C. argyrophylla in any characteristics.
