THE AMERICAN WHITE BIRCH [Betula popuUjoUa) 



The narrow, taper-pointed, triangular leaves are very glutinous when they unfold. They tremble like aspen leaves, atd 

 form a thin foliage mass. The long, pendulous staminate catkin shown has a slim green pistillate one above it. The floweis 

 appear in April before the leaves are half-grown. The narrow, oblong cone has scales with two spreading side lobes. I* 

 wings are broader than the seed. The bark is dirty white and marked with a conspicuous black triangle or an inverted V undfr 

 ^ach branch. The bark can with difficulty be stripped horizontally. It is not easily separable into thin sheets. The bases - 

 old trunks become dark and furrowed
