Gomortega keule (syn. G. nitida; Spanish names keule, queule, and hualhual) is a tree native to Chile. It is the sole species of the genus Gomortega and, according to the APG IV system of 2016 (unchanged from the APG systems of 2009, 2003 and 1998), of the monotypic family Gomortegaceae, assigned to the order Laurales in the clade magnoliids.^[3]

Description[]

Fruits of G. keule

Evergreen trees, aromatic, gray bark with shallow longitudinal fissures. The leaves are petiolate, simple, entire, obovate to lanceolate, coriaceous. The stems have unilacunar nodes and with two foliar traces. The branches are quadrangular.

The edible fruit is a uni or trilocular yellow drupe, usually with 1 (-2) seeds, fleshy mesocarp, pleasant, stony endocarp. There are 1-2 seeds per fruit, with abundant, oily endosperm, large embryo, dicotyledonous.

The chromosome number is n = 21, 2n = 42.

Distribution[]

Gomortega keule grows only in a very narrow habitat range in coastal Central Chile, including the Maulino forest^[4] and parts of the Chilean matorral.^[5] It is a characterisc tree species of the Maulino forest alongside Nothofagus glauca, Nothofagus leonii and Nothofagus alessandri.^[4]

The species is endangered of extinction due to overharvesting, clearing the forests where it is found for agriculture and silviculture.^{[dubious – discuss]}

Gomortega keule produces a yellow edible sweet fruit about 34–45 millimetres (1.3–1.8 in) in diameter, harvested for making a kind of marmalade.
