| Nothofagus obliqua (Mirb.) Oerst. |
Nothofagus obliqua, (Roble, Hualle, Coyán) is a deciduous tree from Chile and Argentina. Coyan grows from 33 to 43° South Latitude, in Chile and Argentina. It reaches up to 50 meters (175 ft) in height1 and 2 m (6.5 ft) diameter. Gray-brownish bark.
Its trunk is dark brown, and very often forked into two main branches. 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 therefore inconspicuous.
Wood: White-yellowish color, it has a beautiful engraving, it is valued for its durability and is used in furniture and construction. This tree was introduced to the British Isles in 18492. Material with provenance from different places in its natural environment was tested in cultivation in Scotland. Trees cultivated from material collected from Ñuble, 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 70’s 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 results3. It has also been introduced also to the North Pacific Coast of the United States4.
