Fagus grandifolia this is not considered distinct in the Flora of North America. The Mexican beech ("Fagus mexicana"), native to the mountains of central Mexico, is closely related, and is sometimes treated as a subspecies of American beech, but more often as a distinct species. The only "Fagus" species found in the Western Hemisphere (assuming "F. mexicana" is treated as a subspecies), "F. grandifolia" is believed to have spanned the width of the North American continent all the way to the Pacific coast before the last ice age.

Cepaea sylvatica these snails is smaller than that of grove snails; the brown area is continuous; and the spire of the shell is blunt. Cepaea sylvatica " Cepaea sylvatica" is a medium-sized species of air-breathing dextral land snail, a terrestrial pulmonate gastropod mollusc in the family Helicidae. It is a close relative of the grove snail ("Cepaea nemoralis"). This species lives in many of the same habitats as "Cepaea nemoralis", such as woods, dunes and grassland, however "C. sylvatica" tolerates wetter and colder areas than the grove snail can tolerate. "Cepaea sylvatica" is generally similar in appearance to "C. nemoralis", although the
