"Genus Cathaya" refers to a group of coniferous trees that grow in China and Vietnam. This genus was named after the Chinese botanist, Hu Xiansu, who discovered the tree in 1955. The Cathaya tree has been described as a less-known, but majestic tree with tall slender trunks and dense, bushy foliage. Some synonyms for "Genus Cathaya" include Cathay fir, Chinese fir, and Keteleeria. These trees are known for their unique beauty and the valuable timber that they produce. Due to over-harvesting and habitat destruction, the Cathaya trees are now considered endangered, making their conservation a critical issue.
