Nothotsuga is a genus of coniferous trees in the family Pinaceae endemic to China.

Nothotsuga contains only one living species, Nothotsuga longibracteata, commonly known as the bristlecone hemlock or chang bao tie shan (长苞铁杉),[3] which is found in southeastern China, in southern Fujian, northern Guangdong, northeast Guangxi, northeast Guizhou, and southwest Hunan.

The leaves are flat, needle-like, 1.2–4 cm (0.5–1.6 in) long and 1–2 mm (0.04–0.08 in) broad, very similar to those of Tsuga.

The cones are very similar to those of Keteleeria, but smaller, 2.5–5 cm (1–2 in) long, erect, and mature in about 6–8 months after pollination.

[citation needed] 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.
