|Keteleeria evelyniana leaves|
The genus name Keteleeria honours J.B. Keteleer (1813–1903), a French nurseryman. The group is related to the genera Nothotsuga and Pseudolarix. It is distinguished from Nothotsuga by the much larger cones, and from Pseudolarix by the evergreen leaves and the cones not disintegrating readily at maturity. All three genera share the unusual feature of male cones produced in umbels of several together from a single bud, and also in their ability, very rare in the Pinaceae, of being able to coppice.
They are evergreen trees reaching 35 m (115 ft) tall. The leaves are flat, needle-like, 1.5–7 cm (9⁄16–2 3⁄4 in) long and 2–4 cm (13⁄16–1 9⁄16 in) broad. The cones are erect, 6–22 cm (2 3⁄8–8 11⁄16 in) long, and mature in about 6–8 months after pollination; cone size and scale shape is very variable within all three species.
The variability of the cones has led in the past to the description of several additional species (up to 16 'species' have been named), but most authorities now only accept three species. Flora of China, however, recognized five.

Fossil pollen of Keteleeria caucasica have been recovered from strata of the Late Miocene in Georgia in the Caucasus region. Keteleeria sp. fossils are also known from the early Pleistocene of southern Portugal.
