Not to be confused with
Birch. Beech (Fagus) is a genus of ten
species of
deciduous trees in the family
Fagaceae, native to temperate
Europe,
Asia, and
North America. Beech was a late entrant to Britain after the last glaciation, and may have been restricted to basic soils in the south of England. Today, beech is widely planted for hedging and in deciduous woodlands, and mature, regenerating stands occur throughout mainland Britain below about 650m. 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 bark is smooth and light gray. 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 are called beechmast.
