Cunninghamia lanceolata (Lamb.) Hook.
Cunninghamia is a genus of one or two living species of evergreen coniferous trees in the cypress family Cupressaceae. They are native to China, Taiwan, northern Vietnam and Laos, where they may reach 50 m in height. In vernacular use, it is most often known as Cunninghamia, but is also sometimes called "China-fir" (though it is not a fir). The genus name Cunninghamia honours Dr. James Cunningham, a British doctor who introduced this species into cultivation in 1702 and botanist Allan Cunningham.
The genus is traditionally said to contain two similar species, Cunninghamia lanceolata and C. konishii, often referred to as the China fir and Taiwan fir, respectively. C. lanceolata occurs in mainland China, Vietnam, and Laos, whereas C. konishii is restricted to Taiwan. However, molecular genetic evidence is suggesting that they are the same species, and that C. konishii of Taiwan derive from multiple colonizations from the mainland. As C. lanceolata was the first name published, this name takes priority if the two are combined. In that case, Taiwan fir becomes Cunninghamia lanceolata var. konishii. However, there is no consensus yet as to whether the two species should be combined.
In the past, the genus was usually treated in the family Taxodiaceae, but this family is now included within the Cupressaceae. A few botanists have also treated it in a family of its own, Cunninghamiaceae, but this is not widely followed. In the fossil record, Cunninghamia is also known from America.
