Nothofagus obliqua


Nothofagus obliqua, (Roble or roble beech (usually found in north america), Hualle, Coyan) is a deciduous tree from Chile and Argentina. It grows from 33 to 43 South Latitude, in Chile and Argentina. The northern extent of this tree's range in Chile is considered to be the Vizcachas Mountains and La Campana National Park.

Description

N. obliqua reaches a height of 50 meters (175 ft). and 2 m (6.5 ft) diameter.

It has gray-brownish or dark brown bark. The trunk is often forked. It has alternate leaves somewhat curled between the veins and the serrated margin. It has separate male and female flowers, both are small and are surrounded by green colored bracts, and rather inconspicuous.

The wood is white, somewhat yellowish. It has a good figure, is valued for its durability, and is used in furniture and construction.

Cultivation

The tree was introduced to the British Isles in 1849. Material with provenance from different places in its natural environment was tested in cultivation in Scotland. Trees cultivated from material collected from Nuble, which is the provenance closest place to the Equator, were the most damaged by frosts. Unfortunately seeds of that provenance were supplied to many commercial growers in the 70s in the United Kingdom. Seeds sourced from Neuquen in Argentina proved the hardiest. A selection from Malleco, Chile, which is the provenance the first trees planted in the British Isles also gave good hardiness results. It has also been planted also in the North Pacific Coast of the United States.
