Quercus marcocarpa, the bur oak, is the tree featuring the largest acorns of any North American oak species, notes the âNational Audubon Society Field Guide to Trees: Eastern Region.â In comparison to the fruits of other oaks, they are huge.
Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaf with smooth margins. Many deciduous species are marcescent, not dropping dead leaves until spring. In spring, a single oak tree produces both male flowers (in the form of catkins) and small coon flowers. The fruit is a nut called an acorn, borne in a cup-like structure known as a cupule; each acorn contains one seed (rarely two or three) and takes 6â18 months to mature, depending on their species.
