Nothofagus fusca is arepresentative of the false beeches ( Nothofagus ) that occursonly in New Zealand .

features

Nothofagus fusca is a tree and reaches heights of up to 30 m. The trunk can reach a diameter of 2 m or more, it is often spongy .

The leaves are rather thin and leathery. They are 20 - 40 × 15 - 25 mm in size. The petiole is up to 4 mm long. The leaf blade is glabrous, with the exception of the nerves on the underside of the leaf. The blade is broad-oval to oval-elongated. The leaf margin is coarse and rather deep and sharply serrated, with 6 to 8 pairs of teeth. There are one or two domatia in the basal nerve axils . Young plants usually have thinner and more toothed leaves.

The male inflorescences stand alone up to eight on the branches. The inflorescence stalks are glabrous and up to 4 mm long. They have one to three, rarely five flowers. The perigone is 5 mm long, bell-shaped and flat truncated five-lobed. It is barely to densely hairy. There are 8 to 11 stamens . The anthers are 2 mm long, red, yellow or straw yellow. The female inflorescences are up to five on the branch, are sessile, egg-shaped to spherical, 3 mm long, glabrous and usually consist of three flowers. The lateral flowers are threefold, the terminal one is twofold. The scars are tongue-shaped and clearly bilobed. The cupula is hairy and four-part. The nuts are 7 mm long, triangular or flat. The wings are wide and wedge-shaped at the base.

The wood is fresh, dark red. The bark is you, dark, furrowed with large scales.

Distribution and locations

Nothofagus fusca occurs on both main islands of New Zealand, from the 37th parallel south. However, it is missing on Mount Egmont . It grows in lowland and mountain forests.

It prefers hilly and valley floors inland, especially where the soils are fertile and well drained. A mycorrhizal partner of the species is the mushroom boletopsis nothofagi .

Taxonomy

Nothofagus fusca was first described as Fagus fusca by Joseph Dalton Hooker in 1844 . The first description appeared in the seventh edition of Icones Plantarum by his father William Jackson Hooker . The type document is in the Royal Botanic Gardens, Kew and was collected by the Reverend William Colenso .

In 1873 the species was transferred from Ørsted to the genus Nothofagus .
