Quercus macrocarpa x (Q. macrocarpa x turbinella) | Davis
Here is how Shields Grove records tree names, in this case, one of many Cottam hybrids that survive in the Grove. It's fascinating to compare these oaks to similar oaks found at the University of Utah. The trees are the same age, and, in many cases, siblings. But the vastly deeper soils of Davis, and the much longer growing season, have produced much, much larger trees in Davis.
