Nothotsuga
Nothotsuga is a genus of coniferous trees in the family Pinaceae endemic to China. "Nothotsuga" contains only one species, Nothotsuga longibracteata, commonly known as the bristlecone hemlock, which is found in southeastern China, in southern Fujian, northern Guangdong, northeast Guangxi, northeast Guizhou, and southwest Hunan. Description. "N. longibracteata" is an evergreen tree reaching tall. The leaves are flat, needle-like, long and broad, very similar to those of "Tsuga". The cones are very similar to those of "Keteleeria", but smaller, long, erect, and mature in about 6–8 months after pollination. Taxonomy. In many respects, "Nothotsuga" is intermediate between the  genera "Keteleeria" and "Tsuga". It was discovered in 1932, and at first treated as "Tsuga longibracteata", being classified in its own genus in 1989 when new research indicated how distinct it is from other species of "Tsuga" - by the larger, erect cones with exserted bracts, and (like "Keteleeria") male cones in umbels, and from "Keteleeria" by the shorter leaves and smaller cones. Conservation. It is a very rare tree listed as a near-threatened species by the International Union for Conservation of Nature due to historical deforestation, though it is now protected.
