--><p>On the Edwards Plateau of Texas, <i>Quercus laceyi</i> occurs mostly at 350-600 m elevation; in Coahuila and Nuevo León, it occurs at 1500-2200 m. This species is sometimes associated with remnant mesic forests, which include Acer grandidentatum Nuttall, <i>Tilia</i> species, <i>Quercus</i> muhlenbergii Engelmann, and various pine and other oak species. The leaves are shallowly lobed or entire, although occasional specimens on moist sites are deeply lobed and resemble the leaves of <i>Q. alba</i> in outline.</p>
