Cathaya argyrophylla (Yin Shan) Chun & Kuang 1962
vulnerable plant species in the pinaceae family
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 characters.

Zenia insignis Chun 1946
plant species in the fabaceae family
Zenia is a genus of plants in the family Fabaceae. It belongs to the subfamily Dialioideae. It contains a single species, Zenia insignis. The Fabaceae family is known for their extraordinary ability to be efficient in symbiotic nitrogen-fixation. The Papilionoidea and Caesalpinioideae subfamilies have been found to be the two sister families that the Z. insignis seemed to diverge from, through the evidence of fossil calibration points. Based on genetic research, the Z. insignis appears to have lost the genes relating to key-nodulation during its evolution. This results in the tree's inability
