Yellow birch (Betula alleghaniensis)
Large, height 60' to 70'; diameter 24" to 36"; in the open, trunks are usually short and divide into numerous large ascending limbs that form a broad open head; under forest conditions, trunks are tall and clear of limbs.
Yellow gray or straw color; peeling freely into thin papery layers that produce a ragged appearance on the main stem and lower branches; twigs light brown, lustrous, and slightly aromatic with oil of wintergreen.
Simple, alternate on stem, length 3" to 5"; oval to oblong, deeply and finely toothed; dull dark green on upper surface and paler beneath; much larger than paper birch; turns bright yellow in autumn.
Chestnut-brown winged nutlets contained in a cone-shaped catkin about 1" long.
Common in the northern half of the state on better soils where cool, moist conditions prevail; moderately shade tolerant, moderately fast growing.
