Kinds of Timber
Birch
Birch is the name of any tree of the genus Betula, in the family Betulaceae, closely related to the beech/oak family, Fagaceae. These are generally small to medium-size trees or shrubs, mostly of northern temperate climates. The bark of all birches is characteristically marked with long horizontal lenticels, and often separates into thin papery plates, especially upon the Paper Birch. It is practically imperishable, due to the resinous oil which it contains. Its decided color gives the common names Red, White, Black, and Yellow to different species.
Beech
(Fagus) is a genus of ten species of deciduous trees in the family Fagaceae, native to temperate Europe, Asia, and North America. The leaves are entire or sparsely toothed, from 5-15 cm long and 4-10 cm broad. The flowers are small single-sex, wind-pollinated catkins, produced in spring shortly after the new leaves appear. The fruit is a small, sharply 3-angled nut 10-15 mm long, borne in pairs in soft-spined husks 1.5-2.5 cm long, known as cupules. The nuts are edible, though bitter with a high tannin content, and can be called beechmast.
