About Nothofagus glauca (Phil.) Krasser
Nothofagus glauca (Phil.) Krasser grows up to 30 meters (100 feet) tall and up to 2 meters (6.5 feet) in diameter, with a straight, cylindrical trunk. Its bark is gray-reddish and rough. This species grows in locations with long periods of drought. It is very useful for reforesting areas with highly sloped terrain and long dry summer seasons. It is currently threatened by habitat loss.
Its leaves grow in an alternate arrangement; leaf petioles are 2–7 mm long. Leaves are ovate, with a subcordate base. Glands are present on both leaf surfaces, giving the leaves a harsh texture; the upper leaf surface is glaucous. Leaf margins are undulate and irregularly serrate. The twisted leaf blade is 5–9 cm long, with prominent pinnate venation.
Flowers are unisexual and small. Male flowers are solitary, grow on pedicels up to 1 cm long, and bear 50 stamens. Female flowers are arranged in groups of three within each inflorescence. The fruit is a cupule with 4 narrow valves, holding three yellowish, pilose nuts that are 12–20 mm long. The two lower nuts are triangular and tri-winged, while the internal nut is flat and bi-winged.
