Nothotsuga longibracteata

It is an evergreen tree reaching 30 m tall. The leaves are flat, needle-like, 1.2-4 cm long and 1-2 mm broad, very similar to those of Tsuga. The cones are very similar to those of Keteleeria but smaller, 2.5-5 cm long, erect, and mature in about 6-8 months after pollination.

Nothotsuga longibracteata, Tsuga mertensiana, and Tsuga canadensis on all three gene phylogenies provides evidence against previous hypotheses of intergeneric hybrid origins of N. longibracteata and T. mertensiana. Divergence times of the genera were estimated based on sequence divergence of the matK gene, and they correspond well with the fossil record.
