| 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 (164 ft) height[1] and 2 m (6.5 ft) diameter. Gray-brownish bark.
Its trunk is dark brown and very often fork in two main branches. It has alternate leaves with curlings between nervation and serrated margin. Having male and female flowers, both are small and are surrounded by green colored bract, and therefore little visible.
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 in the British Islands in 1849[2]. Provenance from different places from its natural environment was tested in cultivation in Scotland. Trees recollected from Ñuble , which is the closest place to the Equator line, which are the most damaged by frosts, unfortunately seeds from that place were supplied to a lot of commercial growers in the 70’s in the United Kingdom. Provenance sources from Neuquen in Argentina were the hardiest. Selection from Malleco, Chile, which is the place from first trees were planted in the British Islands gave good hardiness results[3]. And it has been introduced also to the North Pacific Coast of the United States[4].
