Liriodendron tulipifera (Tulip tree) Magnoliaceae (Magnolia family)
		Tree growing against the east wall of the Human Nutrition building, across the lawn from the water feature at the south entrance to MacKay Hall.
	Liriodendrons are not related to true poplar trees (Populus) and there are only two species of liriodendrons in the world. Occasionally planted as an ornamental tree in central Iowa, the tulip poplar is not reliably hardy further north. Flowers appear in spring as large, tulip-shaped, solitary blooms at the ends of the branchlets. The greenish-yellow, cup-like flowers have a surprising band of bright orange on the inside and a central, cone-shaped axis bearing the sexual structures.
