Carpinus betulus GSB formal planting. John Rawlings, 26 Sep 2005

Carpinus, a name that presumably means small-fruited, receives honorable mention by classical Latin authors, for example by Vitruvius, who extols the wood’s durability and strength, features that favor its use for hammer and chisel handles today. Until recently it was also used widely to make gear wheels and other machine parts benefiting from impact resistance. The smooth bark is light gray. The finely-toothed leaves resemble birch and alder leaves but the conspicuous catkins, though similar in plan, are distinguished by large papery three-lobed bracts whose dominant central lobes may be almost as long as the leaves.

There are 18 of variety ‘Fastigiata’ in the formal planting of Knight Plaza (between the Graduate School of Business and the Knight building) and many more at the Cantor Center.
