-- Sub-genus Quercus, section Lobatae, Series Erythromexicanae, Group Acutifoliae;
-- The name honors Doctor Jorge Meave del Castillo, Mexican botanist;
-- Threatened (IUCN Red List Category : VU).

-- 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).
