description
Betula alba is a deciduous tree of the Betulaceae family that can reach
heights of 50-80 ft. The tree has a slender trunk with white bark that often
has black diamond-shaped marks or larger patches, particularly at the base.
The shoots are rough with small warts and are hairless. The leaves are 1-2
inches long, triangular with a broad base and pointed tip, and have coarsely
double-toothed serrated margins.
The flowers are wind-pollinated catkins,
produced before the leaves in early spring. The small winged seeds ripen
in late summer on pendulous, cylindrical catkins.
common names
& nomenclature
The name is a very ancient one, probably derived from the Sanscrit bhurga,
'a tree whose bark is used for writing upon.' From its uses in boat-building
and roofing it is also connected with the A.S. beorgan, 'to protect or
shelter.'
