Growing in association with Rhus sp., Liatris aspera (white and purple), Juniperus virginiana, Quercus rubra, Quercus macrocarpa, and Schizachyrium scoparium. | Wild material | Specimens at the collection site in nature are represented as very large/old plants, approximately 5.0 meters in height with trunk diameters to 25.0 cm. After 15 years of growth in cultivation in central Iowa, specimens average approximately 3.5 x 3.5 meters. This species is reported to sucker, but all specimens of this accession have shown no signs of suckering while grown in cultivation. Peak fall color tends to occur during the second week in October in central Iowa ranging from reddish-orange; brownish-red, brownish-orange, etc. Acorn production tends to be consistently heavy every year and can initiate production after three years in age. Peak fruiting tends to occur between 5-15 of September in central Iowa, which is approximately 1 week prior to Q. muehlenbergii. Acorns are extremely favored by deer, rabbits, raccoons, turkeys and bluejays. Quercus prinoides in Nebraska is extremely rare. To date (2022), only two counties totalling four localities have recorded this taxa including Richardson County: two areas near Salem; one in Indian Caves State Park and one in Nemaha County described as near Nemaha. Species tends to be restricted to dry rocky upland hills and bluffs. Recent research (Hipp et al., 2019), noted that using the unweighted pair group method with arithmetic mean and non-metric multidimensional scaling ordination did not separate individuals of Q. muehlenbergii and Q. prinoides as distinct species. However, W. M. Keith Jr. (1957) states that "Q. muehlenbergii never spreads vegetatively and acorns are rarely borne until it has attained small tree size whereas Q. prinoides bears at extremely small sizes, usually a foot or so high and spreads vegetatively via rhizomes". Therefore, genetics of this accession most likely represents the hybrid of Q. prinoides x Q. muehlenbergii under the assumption that the true Q. prinoides is represented only by those that clonally spread via rhizomes. Further research is needed to clarify the identity of Q. prinoides. This accession is therefore being listed as Q. hybr. Specimens are clearly "dwarf" or shrubby in growth habit and produce acorns at extremely early ages, but do not spread via rhizomes. | 1543547 | Ames 23752 |

All the plants found in this habitat go through periods of drought during the growing season due to the limited litter/soil layer in which moisture can be held. Elevation: 405 to 430 meters. Slope: 5 to 25 percent. Aspect: various. Geology: The underlying geology of this area is of Silurian origin and comprised of Shawangunk Formation. This formation is primarily light- to dark-gray, fine- to very coarse-grained sandstone and conglomerate containing thin shale interbeds. (Source: USGS Pennsylvania Geologic Map Data). Soils: The surface soil profile of this area is characterized as the Hazleton Series which consists of deep and very deep, well drained soils formed in residuum of acid gray, brown or red sandstone on uplands. The matrix includes a considerable accumulation of thin, flat, coarse fragments of sandstone, limestone, or schist with diameters up to 15 cm. Slope ranges from 0-80%. Permeability is moderately rapid to rapid. (Source: USDA-NRCS Official Soil Series Descriptions). EPA Ecoregion (Level III): Ridge and Valley (67).
