-- Sub-genus Quercus, section Lobatae, Series Erythromexicanae, Group Acutifoliae;
-- The name honors Doctor Jorge Meave del Castillo, Mexican botanist;
-- In the Acutifoliae Group, the species with biennal maturing acorn (Q. skinneri, acutifolia, grahamii, albocincta, xalapensis, furfuracea, uxoris, meavei) are often difficult to distinguish, as they all have hairless or nearly so leaves and aristate teeth, so the presence of acorns is necessary ; concerning Q. meavei, the confusion is possible with Q. xalapensis, Q. skinneri ( but these ones have twigs and petiol glabrous or nearly so, and veins flat adaxially), and with Q. uxoris (which has only 10-14 veins pairs, a cup flattened, an acorn with depressed, tomentose apex); Q. meavei differs from Q. furfuracea which has as well a yellowish tomentum on twigs and petiol, but which has only 6-9 vein pairs, narrower leaves (no more than 5 cm) and shorter teeth (14 mm).
