Monoecious; male flowers are yellow-green, borne in long, drooping slender catkins, 2 to 4 inches long; female flowers are green tinged in red and appear as single, short spikes, both appear shortly after the leaves.

Quite stout, yellow-brown, often with corky ridges; multiple terminal buds are small, round, and may be somewhat pubescent often surrounded by thread-like stipules; laterals are similar, but smaller.

Ashy gray to brown in color and quite scaly, but noticeably ridged vertically on large trees. Form: A large tree that often reaches over 100 feet tall with a long clear bole. In the open it becomes a very wide, spreading tree.
