Tulip-tree (Liriodendron tulipifera)
Tulip-tree (Liriodendron tulipifera) is a fast-growing forest tree. Its flowers look somewhat like tulips (no relation though).
Quack, quack. The terminal bud of tulip tree is elongate, with valvate scales (i.e., in pairs meeting end-to-end) looking quite like a duck’s bill. Quack-quack.
Oooh, ooh. Stipule scars! These stipule scars completely encircle the twig.
Tulip tree has an unusual pith type; it’s “diaphragmed.” Filled throughout the inner cylinder, AND there are cross walls. Yippee!
