The chile cedar ( Austrocedrus chilensis ) is a type of conifer in the cypress family (Cupressaceae). The tree species native to southern South America is the only representative of the Austrocedrus genus .
description
The Chile cedar grows as an evergreen tree and reaches heights of up to 25 m. When young, the tree forms a dense, columnar crown . The bark is gray to reddish brown and finely scaled.
The alternate foliage with shed leaves resembles that of Thuja . The small, flat, fern-like branches are striped bluish underneath.
Small, narrow cones with two pairs of scales are formed. The lower scales are smaller and bent back. The small seeds are two-winged with unequal wings; usually the cone contains four seeds.
The wood of the Chile cedar is reddish.
Distribution and location
The home of this species is in southern Chile and southern Argentina . It grows there in the Andes at altitudes of 900 to 1800 meters. In the north-south direction, the distribution area in Chile extends from latitudes 32 ° 40 'to 43 ° 30' south; This makes it the most northerly occurring of all conifer species in the forests of the Patagonian Andes. Their northernmost locations are at exposed altitudes and are scattered.
Reforestation programs are endangered by fire and introduced herbivores (deer and cattle).
The species is not hardy in Central Europe.
Systematics
The description of the species by the British botanist David Don under the taxon Thuja chilensis was published in 1832. The Austrian botanist Stephan Ladislaus Endlicher assigned the species to the genus Libocedrus under the taxon Libocedrus chilensis . Carl Rudolf Florin and Julius B. Boutelje put the species in its own genus Austrocedrus in 1954 ; however, their description of the species Austrocedrus chilensis contained a formal error, as it only refers to Libocedrus chilensis (D. Don) Endl. but not the real Basionym Thuja chilensis D.Don . This explains why the current description by Rodolfo Emilio Giuseppe Pichi Sermolli and Maria Paola Bizzarri is much more recent, from 1978.
Another synonym for the species is Thuja andina Poepp. et Endl.
use
The reddish, fragrant wood of the Chile cedar is durable and easy to work with. It is used in art and furniture carpentry.
Multiplication
Propagation is possible by seeds or cuttings . The seeds have to be cold- stratified in order to be able to germinate .
